Journal of research in Biology (2011) 2: 148-152
Abstract:
Air pollution tolerance index (APTI) has been determined by pooling the at-tributes viz., total chlorophyll, ascorbic acid and moisture content of leaves and leaf extract pH for certain locally available tree species in and around Kothagiri Municipal Town, the Nilgiris. Of the 24 species analyzed 6 tree species such as Alnus nepalensis, Callistemon lanceolata, Eucalyptus ficifolia, Ficus elastica, Michelia champaca and Toona ciliate recorded higher APTI values. Hence, it is suggested that these tree spe-cies can be given priority for plantation programme in and around industrial com-plexes, road sides and also new urbanized areas in Kotagiri so as to reduce the effect of air pollution and makes the environment clean.
Phytoremediation potential of native plant species for gaseous pollution from...Innspub Net
In developing countries, brick kilns are not well regulated by government agencies. As a result most of the time they are installed near to the cities to reduce transport cost. They use coal, waste plastic, scrap tires, etc as fuel. Brick kiln produces number of toxic pollutant like CO2, SOx, NOx, HF, etc. They produce tons of gaseous pollution which effect near and far settled human population. Phytoremediation is considered the most suitable option for developing countries because of low cost, eco-friendliness and easily manageable. In current study, the purpose was to identify tolerant plant species near the brick kilns by measuring air pollution tolerance index (APTI). Species of trees including Mangifera indica, Morus alba, Acacia nilotica, Eucalyptus globulus, Dalbergia sissoo and Moringa oleifera were selected for sampling. Samples were collected during July and December at 100m, 300m, 500m and 700m distance around the brick kilns from two selected sampling sites. Moringa oleifera (APTI=17.60) was identified as tolerant and a sink of hydrogen fluoride (HF). Whereas, Eucalyptus globules (APTI=9.91) was found sensitive, so it can be used as bio-indicator of HF. This study recommends the plantation of Moringa oleifera around brick kiln for HF phytoremediation.

ABSTRACT- For every life form, water is an essential natural element. Ever increasing growth of population, especially
in developing country like India, have affected not only surface but also ground water quality and is main cause for
environmental pollution. The most possible sources of soil, water and plant pollutions are sewage sludge, residues of
industrial factories and intensive fertilization. Increased organic matter (from the sewage) breaking down in the river
reduces the amount of dissolved oxygen in the water body as the decomposition process uses up the available dissolved
oxygen. Microbial pathogens introduced by sewage into surface or groundwater can threaten public health, as well as
affect ecosystem health and function. Today as demand for fresh water intensifies, the use of municipal or sewage
wastewater as alternative source of water for irrigation purpose is also a common practice. The present study was
conducted to assess the physicochemical parameters of the Rispana river where sewage is dumped and also effect of this
sewage wastewater on selected plant Vigna radiata. The findings of the study indicated a direct influence of sewage
wastewater on the plantlets and decrease in overall growth of plant with increase in concentration of wastewater.

— The present study was conducted to evaluate the plant growth, physiological and biochemical changes of neem under different salinity levels (4, 8, 10 and 12 dS/m) which have multipurpose use in agroforestry. Growth parameters, photosynthetic pigments, carbohydrate, proline and total phenol were investigated 30, 60, 90 and 120 days after treatment imposition. The results revealed that salinity caused significant differences in all the growth parameters and the maximum reduction were observed when plants were exposed to high salinity (12 dS/m) level and minimum were in control treatments. It was found that total dry matter and relative water content were reduced 72% and 40% in 12 dS/m compared to control plants at 120 DATI, respectively. By increasing saliniy 0 to 12 dS/m, the chlorophyll (the photosynthetic pigment) and carbohydrate (the photosynthetic product) content decreased, but increased the level of proline (an amino acid) and total phenol content (an antioxidant) in different days. The highest accumulation of free proline and total phenol content was recorded in 10 dS/m treatment and it was 77% and 59% greater than control plant, respectively. These findings suggest that though growth and biochemical parameters of neem were affected by salt stress, but all the plants survived in different salinity levels. Among all different salinity levels, neem can performed better up to 10 dS/m salinity level could be due to better antioxidant system of neem to cope up with oxidative damage to stressed plants.
Removal of Heavy Metals from Waste Water Using Water HyacinthIDES Editor
Water pollution has become one of the most serious
problems of today’s civilization. In the last few years
considerable amount of research has been done on the
potential of aquatic macrophytes for pollutant removal or even
as bio-indicators for heavy metals in aquatic ecosystems. Water
hyacinth is one of the aquatic plant species successfully used
for wastewater treatment. It is very efficient in removing
pollutants like suspended solids, BOD, organic matter, heavy
metals and pathogens. This paper mainly focuses on the
treatment of waste water using the plant ‘water hyacinth’ and
has given emphasis to the removal of heavy metals by the
plant. Water hyacinth’ could grow in sewage; they absorb and
digest the pollutants in wastewater, thus converting sewage
effluents to relatively clean water. Thus, the plants hold
promise as a natural water purification system, which could
be established at a fraction of the cost of a conventional sewage
treatment facility. The study conducted in this regard revealed
how efficiently wastewater could be treated using the plant
‘Water hyacinth’.

Assessment of Heavy Metal Contamination in Vegetables Grown in and Around Nas...IOSR Journals
The study was conducted to find out the content of lead (Pb), cadmium (Cd), arsenic (As) and copper (Cu) in some selected vegetables grown in and around Nashik city, Maharashtra state (India). Vegetable samples from four different sites were collected and digested by using tri-acid digestion method. Concentrations of heavy metals were analyzed by using atomic absorption spectrophotometer. The results of this study showed that there was wide variation in the concentration of these metals in vegetables collected from different sites. Vegetables grown in the vicinity of an industrial area were most contaminated while vegetables grown in rural area were least contaminated. Analytical results indicated that the concentration of lead in 35% vegetable samples collected from industrial area were more than maximum permitted limit. The high concentration of cadmium was found in onion and coriander, while lead content was recorded high in spinach and cauliflower. Arsenic concentration in 25% samples collected from industrial area was more than maximum permitted limit. Copper concentration in most of the vegetable sample was within permissible limit; only two out of forty samples have high concentration of copper. The results of the study showed that consumers are at greater risk of purchasing these fresh vegetables with high levels of heavy metals beyond permissible limits as defined by the Indian Prevention of Food Adulteration Act, 1954.

The study examined the concentration of heavy metals
in water, soil and vegetables growing wildly on cement-polluted
soil of Rewa city, India. Accumulation of HMs in vegetables
occurs by various sources but soil is considered the major one. In
this study, soil to vegetable transfer factor (TF) for various HMs
were also calculated and data showed that TF values differed
significantly between soil and vegetable, the difference in TF
values among different vegetables may be attributed to
differences in element uptake by different vegetables. However
TF values obtained for all vegetables were below (1) at all sites.
TF were computed to quantify relative differences in
bioavailability of metals to vegetables to identify the efficiency of
a vegetables species to accumulate a HM(s). These factors were
based on roots uptake of metals and discount the foliar
absorption of atmospheric metal deposits. However TF does not
present the risk associated with the metal in any form.

Impact of Compost Prepared from Invasive Alien Species in Alleviating Water S...YogeshIJTSRD
Invasive alien plant species are major thread to biodiversity, climate change and environmental sustainability. Management of these invasive alien plant species become a typical task at global level. Composting can be an efficient and environment friendly solution for management of these invasive alien species. The aim of present study was to evaluate the effect of compost prepared from three invasive alien species Cuscutareflexa, Eupatorium adenophorum and Lantana camaraon the tomato plant vigour, antioxidant and nutrient content under water deficit and irrigated well watered conditions. The results revealed that Cuscutareflexa CR compost treatment gave highest shoot length 23.0 , 23.7 , root length 30.0 , 21.4 , shoot fresh weight 47.9 , 52.2 , shoot dry weight 71.0 , 49.4 and root dry weight 66.7 , 51.5 , under water stressand irrigated conditions, respectively. The application of compostCR under water stress has enhanced chlorophyll and prolinecontent over control. Similarly, antioxidant enzymes analysis showed the increased superoxide dismutase 1.33 2.17fold , peroxidase 1.38 1.82fold and catalase 1.06 1.73fold activity under water deficit condition. Nutrient content such as nitrogen, phosphorus, potassium and sodiumin tomato leaf were higher under both water stress and irrigated conditions compared to their respective control. It can be concluded from above outcomes that compost prepared from invasive alien species have potential to ameliorate the negative effects of water stress and enhance the tomato growth.

Estimation of Air Pollution Tolerance Index of Plants Across the Industrial Z...IJAEMSJORNAL
One of the world's most serious issues today is air pollution caused by vehicle emissions, which poses a serious threat to both the environment and the health of living things (plants, humans, animals, microorganisms). The most severely impacted plants arVe those growing along side roadsides because they are the ones most frequently exposed to various air pollutants and exhibit a range of tolerance and sensitivity. In light of this, the current study's foundation was an evaluation of seasonal variation in the air pollution tolerance index (APTI). One of the most important sources of air pollution is vehicle emissions. The 11th most highly populated city in India is Kanpur. The parameter used to evaluate the sensitivity and tolerance level of plants based on Air Pollution Tolerance Index (APTI). This study aims to calculate the resistance and sensitivity of various plant species to air pollution. In the majority of developing countries, one of the causes of air pollution is vehicular emissions. Planting along the side of the road is a significant method of reducing the pollution that cars emit. The plants' APTI value is calculated using the pH, relative water content (RWC), total chlorophyll (Tch), and ascorbic acid (Asc) content of the leaves. The leaves of plants were collected from industrial zones Northen railway colony.Based on APTI values, In the industrial area, the most tolerant plant Ficus benghalensis (38.40) and Azadirachta indica (31.16), while lowest APTI value plants species Alstonia scholoaris( 9.5) and Adina cordifolia (11.6.0) in the industrial zone.
Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well as anionic (ethyl orange, metanil yellow, acid blue 113), and phenols (phenol, 2-chlorophenol, 4-chlorophenol and 2,4-dichlorophenol) fruitfully from water. The column type continuous flow operations were used to obtain the breakthrough curves. The breakthrough capacity, exhaustion capacity and degree of column utilization were evaluated from the plots. The results shows that the degree of column utilization for dyes lies in the range 60 to 76% while for phenols was in the range 53-58%. The exhaustion capacities were quite high as compared to the breakthrough capacities and were found to be 217, 211, 104, 126, 233, 248, 267 mg/g for meldola blue, crystal violet, chrysoidine G, methylene blue, ethyl orange, metanil yellow, acid blue 113, respectively and 25.6, 72.2, 82.2 and 197.3 mg/g for phenol, 2-chlorophenol, 4-chlorophenol and 2,4-dichlorophenol, respectively

Particulate matter effect on biometric and biochemical attributes of fruiting...GJESM Publication
Dust accumulation capacity of Ficus carica L. and Psidium guajava L. was investigated from eight
different sites of Multan, Pakistan. Leaves of both plants were used for analyzing biometric (leaf area, fresh and dry
weights) and biochemical attributes (chlorophyll contents, carotenoids and ascorbic acid). Maximum dust accumulation was occurred in the plants growing near road sites, while, minimum dust accumulation occurred in the plants of Bahauddin Zakariya University. Most of the biometric and biochemical attributes of F. carica showed significant response towards dust but it had not significant influence on some attributes of P. guajava. Biochemical traits of P. guajava appeared to be more prone than foliage ones. A positive correlation was found between dust accumulation and foliage attributes in F. carica. On the other hand, in P. guajava opposite was observed, however, the reverse was true for leaf biomass. Biochemical contents had shown an inconsistency as chlorophylls (a, b & total), carotenoid contents declined but ascorbic acid increased with an increase in dust accumulation in both species.

EVALUATION OF INDUSTRIAL EFFLUENTS AND SOIL PROPERTIES NEAR PHARMACEUTICAL CO...IAEME Publication
There has been an increase in number of pharmaceutical companies in the present
time. A large number of them are located in Himachal Pradesh. The effluents from
these industries contaminate the nearby soil and water bodies. Here we analyses the
treated waste water and soil from nearby areas for their physical, chemical and
biological parameters. The samples were analyzed using standard methods according
to WHO & APHA-AWWA-WPCF norms. The results showed a high amount of
contamination. The pHs of the water samples showed contrasting features one being
slightly alkaline while other highly acidic. The microbial activity was quiet low in the
treated waste water while optimum amounts of bacterial and fungal activity was
found in the soil samples near the industries. The presence of high amount of sodium
and salinity was also observed. This could damage the crop productivity and soil
fertility. There is an urgent need to propose strict restrictions on discharge of harmful
effluents in the environment.
The present study investigates the growth and developmental changes of Pearlmillet [(Pennisetum glaucum (L.) R.Br.)] and Ragi [Eleusine coracana (Gaertn )] under pot culture experiments with different concentrations of aqueous leaf extracts (5, 10, 20, 30 and 50g/l) of Teak. Teak leaf extracts showed an inhibitory and stimulatory effects on germination, seedling length, biomass, pigments and biochemical constituents of pearl millet and ragi. The 5g/l concentration of extract stimulated the seed germination, seedling growth and biochemical constituents of pearl millet and ragi.. The higher concentrations (10, 20, 30and 50g/l) showed an inhibitory effects in all the parameters studied in the two economically important cereals. The degree of retardation was dependent on the concentration of the Teak leaf extracts. Root length, Shoot length, Biomass and Biochemical constituents of ragi seedlings were highly reduced at 50g/l concentrations of aqueous leaf
extracts of Teak. Between pearl millet and ragi seedlings, more allelopathic influence was observed in ragi than pearl millet seedlings.

Field experiment was conducted during 2013/2014 and 2015 seasons was aimed to evaluate productivity of Rhodes and Blue panic grasses as well as Alfalfa under sprinkler irrigation with foliar application of potassium nitrate that enable plants to cope with water stress. Each two forage grasses beside alfalfa were conducted in separate experiments. Irrigation every 10 days surpassed in total chlorophyll, leaf area, plant height, number of stems/m 2 , forage green yield/fed and forage dry matter yield/fed than those irrigated every 20 days. Highest percentages of water use efficiency, crude fiber and nitrogen free extract as well as yield/fed of crude protein, crude fiber, ether extract, ash and nitrogen free extract were produced from irrigation every 7 days. However, highest percentages of crude protein, ether extract and ash were produced from irrigation every 14 days. Forage species significantly differed on total chlorophyll, leaf area/plant, plant height, average of number of stem/cm 2 , forage green yield/fed and forage dry matter yield/fed. A significant effect due to forage species on percentages of water use efficiency, crude protein and fiber, extracting ether, ash and nitrogen free extract and nitrogen free extract as well as crude fiber, extracting ether, ash and nitrogen free extract yield/fed. Sown Rhodes grass produced maximum forage green and forage dry matter yield/fed and its quality compared with other studied forage crops. Foliar spraying of potassium nitrate at 15 ppm significantly increased total chlorophyll, leaf area, plant height, number of stems/m 2 , forage green and forage dry matter yield/fed. The results showed that highest percentages of water use efficiency, crude protein, crude fiber and ether extract, and nitrogen free extract and nitrogen free extract as well as crude fiber, extracting ether, ash and nitrogen free extract yield/fed.

Physiological stress indicates the environmental pressures which affect the
plant physiology and change it. The experiment was conducted as split plot in
randomized complete block design with three replications on safflower (Carthamus
tinctorius) from 2015 to 2016. Treatments were: 1) Irrigation: without stress (irrigation
after 70 mm evaporation from evaporation pan class A) and drought stress (irrigation
after 150 mm evaporation from pan class A) was considered as the main factor and
the concentration of salicylic acid with three levels (0.100 and 200 mg L-1) as the first
sub-factor. The second sub-factor includes the concentrations of three levels of
potassium sulphate (0.05 and 1 mg L-1). The interaction between drought stress and
potassium sulphate and also potassium sulphate and salicylic acid were significant on
the induction of plant height. With regard to this, the comparison between salicylic
acid and potassium sulphate interaction on the safflower plant height and the highest
plant height (107.3 cm) was obtained by using 200 mg salicylic acid plus 1 mg L-1 of
potassium sulphate. The combined analysis of data indicated that interaction between
potassium sulphate × salicylic acid on the grain yield was significant. The highest grain
yield (1550 kg ha-1) belonged to the foliar application of 100 mg salicylic acid and 0.5
mg L-1 of potassium sulphate interaction. The interaction of salicylic acid and
potassium sulphate was significant on the biological yield, and the highest biological
yield was obtained with 200 mg L-1 of salicylic acid and 0.5 mg L-1 of potassium
sulphate. Therefore, in order to compensate for some of the harmful effects of stress
and enable the plant to return to normal growing conditions after re-watering, foliar
application of such chemical compounds on plant can be effective and plays an
important role on the resistance of plant to drought.
ABSTRACT- Laccase is multicopper oxidases that are widely distributed among plants, insects, fungi and bacteria. Pollution increased with the
time day by day, laccase is an oxido-reductase which plays a significant role in remediation. These enzyme catalyze and one-electron oxidation of a
wide variety of organic and inorganic substrate including mono-, di-, and poly-phenols, amino-phenols, metho-oxyphenols, aromatic amines, and

Considering the effects of chemical herbicide application, biomarkers have
now become more widely considered for controlling weeds. Allelopathy demonstrates
the potential for this through the release of trace elements from decomposable plant
leaves, seeds, stems and strains. In order to investigate the effects of aqueous extract
of sunflower on the germination and morphological characteristics of Rumex acetosa,
Lepidium draba and Convolvulus arvensis seedlings as three common weeds in sugar
beet fields, a research experiment was carried out in the laboratory of Islamic Azad
University, Neishabour, in 2016 as a factorial in the form of completely randomized
design with four replications. The experimental treatments were aqueous extract of
sunflower (zero, 25%, 50%, 75% and 100%), the type of weed in three levels (Rumex
acetosa, Lepidium draba and Convolvulus arvensis), respectively. The results showed
that the highest percentage and rate of germination were observed in non-use of
sunflower extract (irrigation with distilled water), which in Rumex acetosa 97 and 33
percent were higher respectively, in comparison to Lepidium draba and Convolvulus
arvensis. In the study of stem fresh weight, fresh and dry weight of roots, it showed
that the field bindweed plant was more resistant compared to Rumex acetosa,
Lepidium draba. The lowest germination and seedling traits were obtained in 100% of
sunflower aqueous extract, which affected the weeds of the Ivy and Blacks, and the
sorrel was more resistant. According to the results, sunflower extract as a strong
combination for weed control can have promising results for sustainable agriculture.
In order to have data on the consumption of okra in Ivory Coast, a survey was
carried out in a school in the town of Adjamé among young people aged between 15
and 35 years. The survey showed that all respondents knew okra 57.80% of
respondents appreciate okra fresh, 39.20% dry and 03% do not appreciate at all the
okra. It also showed that 18.60% of respondents appreciate the sauce gombo, 20.80%
gouagouassou the sauce, the 13.80% Kopé sauce, 39.20% djoumblé the sauce, sauces
made 0.8% made from sheets of okra. 06.80% do not like these sauces. All people
surveyed know the varieties of "Gombo baoule" and "Gombo dioula." In conclusion,
the existing prejudices about fresh okra are the dried okra is more popular among
young people in Côte d'Ivoire.
Five diets (diets incorporated with folic acid, vitamin B, vitamin C, vitamin/
mineral mix and control) were used to determine their effects on survival, digestive
enzyme activity, protein profiling and growth of striped snakehead Channa striatus
fingerlings. All vitamin diets showed significant difference in enzyme activity like
protease, amylase and lipase, when compared to that of control. The fingerlings fed
with vitamin C diet showed significantly (P<0.05) better performance in terms of
survival rate, weight gain and Specific Growth Rate (SGR) when compared to the rest
of the four diets. The electrophoretic studies revealed that high molecular weight
fractions were added up in muscle tissue of C. striatus fed with vitamin and mineral
supplemented diets.
Mining is considered as a difficult and harmful job as it is done in a very
difficult physical and environmental condition. In addition to that, miners are exposed
to the dangers, damages and even death because of the bad condition of mines. The
dangers of mines are different in accordance with the kind of mine which may be
underground or surfaces. The dangers may be a bit different in different cities and
mines. Main harmful factors in mining are the physical damages, hyperthermia,
hearing loss, lung diseases, musculoskeletal diseases and facing with dangerous gases
and beams. The purpose of this essay is to examine the effect of physical, chemical
and biological harmful factor on miners. This survey has adopted descriptive method
and data are collected by library method. The results showed that the exposure of
chemical factors such as dust, methane and silica, and physical factors such as noise,
radiation, and biological factors may have great danger for miners.
The intensive study was conuducted for the prevalence and distribution of
Armigeres obturbans for the first time in the rural area surrounding Rajkot City. Seven
villages were identified for the study species identification, larval density, adult
density and distribution of breeding sites of the species. Results showed that adult
density of Ar. obturbans during monsoon was highest and post monsoon period was
most favourable for the species. Also the breeding sites of the species were recorded
more during this period. While during winter season majority of temporary breeding
sites dries out because of temperature decrease. Therefore, the temperature and
rainfall are the two variables that showed major effect on the breeding activities of
this species.
In order to assess the Myxosporeans fauna of Cameroon fresh water fishes so
as to find the fight strategies, 655 specimens (350 Oreochromis niloticus and 305
Barbus callipterus) were sampled in Mapé river (Sanaga basin) and examined.
Standard methods were used for the sampling of fishes, conservation and microscopy.
Morphometric characteristics of the spores were used for species identification. Two
new species belonging to the genus Myxobolus Büstchli, 1882 were described namely
Myxobolus tchoumbouei n. sp in Barbus callipterus which formed cysts within various
organs (fins, skin and operculum); Myxobolus mapei n. sp parasite of kidneys and liver
in Oreochromis niloticus and Barbus callipterus. Myxobolus tchoumbouei exhibited
very long spores (19.19 x 8.89 μm), pear-shaped with rounded anterior end
sometimes flattened. Polar capsules were dissymmetrical. They measured 7.60 x 3.00
μm for the bigger and 7.06 x 2.62 μm for the smaller. Myxobolus mapei n. sp had
ellipsoidal spores (13.50 x 6.83 μm) with unequal polar capsules. The larger polar
capsule (6.44 X 2.88 μm) was about 1.5 times longer than the smaller one (4.13 X 1.61
μm) and filled half of the spiral cavity. The awareness about these parasites is useful
to find fighting strategies.
Hyaluronic acid (HA) is also known by the name hyaluronan. The necessity for
using this fabulous material lead to investigate non-pathogenic strains which produce
this material. The most non-pathogenic strain is S. thermophilus. The lack of literature
on microbial production of this substance by the strain prompted us to examine the
microbial production of HA from it and also to examine optimization of culture
conditions where HA is produced. The bacteria Streptococcus salivarius sub.
thermophilus was obtained from the Bank of Scientific and Industrial Research of Iran
(PTCC 1738). To separate S. thermophilus strains from yogurts, three types of yogurts
were used. They were cultured by pour-plate and surface methods on STA medium. To
identify the isolated strains, biochemical tests and Polymerase Chain Reaction (PCR)
were used. Bacterial strains isolated from yoghurts were identified as S. thermophilus
MN-BM-A02, S. thermophilus JIM8232 and S. thermophilus MN-ZLW-002. To separate
the capsule strains, each strain was cultured on STB medium and then they were
centrifuged. In order to purify the samples, ethanol and charcoal were used. To
optimize production, variety of sources of carbon, nitrogen, temperature and pH were
studied.
The qualitative and quantitative dynamics of the copepod community in
Hendijan harbor was studied through zooplankton samples collected seasonally in
summer 2010 (July- August), autumn 2010 (October), winter 2011 (December-
February) and spring 2011(April). The copepods community was represented by 27
species, belonging to calanoida (16 species), cyclopoida (5 species), Poecilostomatoida
(3 species) and harpacticoida (3 species). The highest abundance of copepods was in
summer (14402±3352 Ind/m3) while the lowest was in winter (852±155 ind/m3). Of
the adult forms, Acartiella faoensis was the most abundant species, forming 19% of
the total copepods, followed by Paracalanus parvus (17%), Corycaeus andrewsi (13%)
and Clausocalanus arcuicornis (8%). Most of copepod species displayed distinct
seasonal occurrence relative to environmental conditions. The spearman’s correlation
revealed that temperature and salinity were the most important factor controlling the
size of copepods density in Hendijan harbor. The cluster analysis demonstrated
different types of association between copepods species. The highest value of
Shannon’s diversity index, Margalef index and Pielou’s evenness was noticed in
summer. These results revealed that the summer is different from other seasons of
the year and in this season the ecological situation is better and more stable than
other seasons in Hendijan shores waters.
The main purpose of this research was to investigate the women pregnancy healthy status and behaviors in Eastern-Azerbaijan province referred to the treatment health centers in 2012. The present study was a cross-section study. So 30
married women between 15-49 years old have been taken up randomly for family adjustment and mother health and pregnancy care. A questionnaire including the demographic features and other questions about the status and behavior of the
pregnancy health affairs were used to collect the results. The obtained data of these questionnaires were analyzed by SPSS software. The results that showed 63.8% had itching or the vaginal stimuli and 34.9% (52 ones) had bad-smelling secretions and
36.9% (55 ones) had intense pain around the abdominal area. The investigation of these infectious diseases through sexual path showed that about 0.5% (3 ones) are challenging with these mentioned disorders. The results of the barrenness showed that about 8.7% (52 ones) tried to get pregnant but they did not get pregnant.
To evaluate the effect of humic acid fertilizer on potato tubers in 2010, trials were conducted in the Province of Iran. The experiment was conducted on a split plot with randomized complete block design having three replications. Main plots consisted of four levels of humic acid (0, 1, 2, 3 times) solution in water irrigation and sub-factor consisted of three varieties of potato (Marfona, Satina, and Born). During planting the application of humic acid at the rate of nine liters per hectare per load at the beginning and start of creating tuber formation respectively were done. Analysis of variance showed that the smallest and largest tuber weight, number of tubers per plant and yield per plant were not significant. Effect of humic acid on the smallest mean tumor weight at 1% and the number of tubers and yield per plant showed significant difference at 5% level. The largest tuber weight was also not significantly different. Interaction of humic acid fertilizer in any of the measured parameters showed no significant difference in potatoes. Comparison by Duncan test showed that the application of humic acid in all the three stages of growth had shown great impact on tuber weight. The highest number of tubers per plant has been associated with the use of humic acid (27 l/ha). The number of tubers per hectare with the application of 18 litres of humic acid showed no significant difference. The amount of humic acid applied were 18 and 27 litres per hectare, and increased performance is in the range of 13 and 29% respectively.
The purpose of this research was to investigate the students' attitude and consciousness degree regarding the pregnancy health in 2013 in Eastern-Azerbaijan Province. So, 300 students in different semesters have been taken up as accidentally from Tabriz, Marand, Bonab, Maragheh and Ahar have been taken up in this study. The WHO illustrative questionnaire for interview-questionnaire designed by John Cleland surveys with young people has been applied in this study. The statistical data has been completed by the help of SPSS software and descriptive and t-test statistical cases. The results showed the attitude score from the family adjustment is significantly higher than the determined degree positively. The results showed the sexual diseases are significantly higher than the fixed determined degree positively. Also it showed there is no observed any significant difference between the degree of the conscious and the students' attitude based on their marital status The results did not show any significant difference regarding the degree of the attitude among students.
The main purpose of the present study was to determine the effect of regular home visits on the developmental indices of low birth weight infants. The present study was an on-site clinical investigation. 90 infants ranging between 1500 to 2500g born in Razi Hospital of Marand town having the entrance criteria to the present study were taken into consideration through the available sampling method and then they were divided into two intervention and control groups. The intervention group has received the whole routine cares since the first to fourth week and then they were visited at home for 45 minutes a week. The control group received the routine cares. The evolutionary indices of both groups were also completed monthly for three months by referring homes. The related data gathering tool was also subjected to the demographic information through registration list and the Persian version of the Low Weight Infant Inventory (LWII) (2 months) that have been completed by the researcher on the birthday, first, second and third months of the birth through the interview. SPSS-15 software and the application of the inferential and descriptive statistical tests (K2 and T-tests) were also applied in order to analyze the related data in this study. The significance level was considered as p<0.05.
More than half of these related research units of both groups had experience (61.5%) and control (55.8%) regarding all women in this study; the mean score of the low weight infants on the first month had not shown any statistical significant difference; but on the second months (p=0.04) and the third months (p=0.001), they had shown statistical significant difference progressively. The healthcare based on home-visit had influence on the recovery indices of the low weight infants. Hence, nurses and other health monitors of the infants should apply for the healthcare programs based on home-visit particularly in caring infants.
Protein was extracted from muscles of Channa striatus and attempts were
made to evaluate in vitro antibacterial activity against clinical bacterial isolates. The
higher concentration of protein (100μg/ml) extracts exhibited a pronounced activity
against Pseudomonas aeruginosa (21 mm), Proteus vulgaris (19 mm), Citrobacter sp
(19 mm), Klebsiella pneumoniae (18 mm), Micrococcus sp (17 mm), Bacillus subtilis (16
mm), Staphylococcus aureus (15 mm), E. coli (14 mm) and Serratia marcescens (5
mm). The minimum inhibitory concentration and minimum bactericidal concentration
were found to be 20-40 μg/ml and 80-100 μg/ml respectively for the extracts of
Channa striatus protein against test organisms. This study confirms that C. striatus fish
protein extracts possess antibacterial activity against a wide range of microbes and
justified that it could be used in the traditional medicine as a remedy for the
treatment of bacterial diseases.
Food security in a growing population with limited natural resources is one of
the most important issues of the world. Accumulation of heavy metals in food and
their concentrations increase and reaching to a risk limit can threaten human health.
The purpose of this study, is to study the heavy metals lead and cadmium in
vegetables, cultured on spinach and watercress at 10 Gardens of Ardabil. This study is
cross-sectional and 81 samples in water, soil, and spinach and watercress were
prepared during the months of June, July and August in 2015 and after preparation
according to the standard methods and using atomic absorption spectrophotometer
(Perkin Elmer) for the determination of heavy metals. SPSS software was used for data
analysis. The results showed that the mean level of lead and cadmium in all samples
were less than the EPA standard. Between studied orchards in terms of the amount of
cadmium and lead no statistically significant different was seen. The independent ttest
showed that in terms of cadmium between two species of spinach and watercress
there found a significant difference at the 5% level so that the amount of cadmium in
spinach was more than the watercress. Since the concentration of heavy metals in all
samples at second and third stages in July and August were zero, but in the first step
in June, the amount of heavy metals have been found in some samples showed that
all three samples of first cut had more contamination than second and third cut. And
in this case, the concentration of heavy metal pollution in hibernation at vegetable
gardens Ardabil is possible. The results of spinach cadmium amount in the first cut in
the three garden of viz.,3, 6 and 10 showed that in the garden (3), the amount of
cadmium in water is higher than the standard and is concentrated in spinach and the
gardens of 6 and 10 Cadmium in the soil of the gardens, is slightly higher that is
condensed in spinach thus it can be considered that spinach in terms of cadmium has
bioaccumulation.
Generally, the reconstitution of palaeo-geography and related environments
is based on the study of sediment markers such as grain size and clay mineralogy. In
this research, 90 surface and subsurface sediment samples from eight cores were
analyzed for grain size and clay mineralogy in southern part of Urmia lake coast and
adjacent areas. Abundant minerals are quartz, feldspars, calcite and dolomite. Heavy
minerals identified were epidote, hornblende and zircon. Clay minerals are Kaolinite
and Smectite mainly. Clay mineralogy and mean grain size of sediments in eight cores
of Urmia Lake; reflect climatic conditions in this region. Relatively coarse sediments
usually deposited during Urmia Lake low stands and relatively fine sediments
deposited during high stands. The mineralogy of the clay-size fraction was determined
by X-ray diffraction (XRD). Mineral assemblages display two climate conditions: Those
having large Kaolinite, quartz, and feldspar peaks but a small smectite peak
(interpreted to be cold times), and those with small Kaolinite, quartz and feldspar
peaks and a large smectite peak-(warm sediments). In addition, smectite content
correlate well with high mean grain size in Urmia Lake sediments, whereas sediments
rich in Kaolinite, quartz, and feldspar correlate well with finer mean grain size.
Chemical elements of the total sample are mainly of terrigenous origin, supplied by
“Discharge Rivers”, which discharges in Urmia Lake. Variations in clay mineralogy and
grain size didn’t indicate that the lake-level variations and nature of sediments
delivered to the lake vary in concert with global climate changes, recently. Human
activities such as Dams’ constructions and agriculture have probably induced
variations in the mobilization of chemical elements.
According to the Convention on the Law of the Sea 1982, constructing
artificial island is permitted and countries can construct artificial islands in their own
territory. Constructing artificial islands in the Persian Gulf area makes the countries in
the region, especially Iran, to pursue the issue with more sensitivity. According to data
dissemination principle of International Environmental Law, the countries that
construct artificial islands should notify other states regarding construction and
properties of their own artificial islands. Today, artificial island construction is being
increased and this has caused many environmental crises including increase of water
darkness and pollution and transport of coastal sediments. In this study, the
destructive results of constructing artificial islands in the Persian Gulf environment,
the effect of development of new land space from geopolitical view, and also
constructing artificial islands from the viewpoint of International Law of the seas have
been reviewed. Moreover, according to the fact that the notion of governance in
modern International Law have been modified regarding the use of environment and
sustainable development, the states will have limited right to construct artificial
islands.
The use of biotechnology in the propagation of plantain and
banana (Musa sp.) of great importance to induce, tolerant to plant genotypes for
diseases and high yield potentials. However, auxins and cytokinins should be used,
which are expensive and can sometimes cause changes in the regenerants obtained.
Both traditional growth regulators (auxins and cytokinins) and non-traditional growth
regulators (brassinosteroid analogues and mixtures oligogalacturonide) are used in
the in vitro propagation of crops, but mush progress has been hindering due to the
sufficient knowledge and impact of different phases prevailing in the
micropropagation of banana hybrid 'FHIA-18' (AAAB) is present hitherto. This work
was performed in order to evaluate the biological activity of an analogue of
brassinosteroids (Biobras-6) *ABr+ and a mixture of oligogalacturonide with the degree
of polymerization between 9 and 16 (Pectimorf) *mOLG+. The effect of ABr and mOLG
are determined as a substitute or complement of auxin (IBA or IAA) and cytokinin (6-
BAP) for the establishment of in vitro multiplication and rooting of plantlets and in the
acclimatization phase. Non-traditional regulators phenolization decrease the explant
growth in the establishment phase of in vitro propagation; but increased the number
of shoots per explants (above 3.5) and improved survival of vitro plant during the
acclimatization phase.
Kumaun Himalaya, in the Indian Himalayan region, has a rich diversity of
medicinal plants, which are widely used in traditional medicinal systems. The present
paper concludes the diversity, vernacular names, associated authorship, ethnomedicinal
uses and use pattern, life form; plant part used and accession number of the
medicinal flora together. The paper describes distribution and local/traditional uses of
the 256 medicinal plants representing 96 families, in which pteridophytes were 1%,
trees were 18%, shrubs were 25%, herbs were 52%). Various plant parts used in
formulations, such as: underground part- 33%, leaves- 24%, whole plant- 11%, bark-
7%, seeds- 7%, resin /latex/oil- 4%, stem/ shoot/ wood- 4%, flowers and
inflorescences- 5%, fruits and nuts- 5% were used in different ailments.
There is a great contamination of water, soil, air, soil erosion, pest resistance
and extensive use of chemical fertilizers cause a turn to induce agriculture for
producing safe and clean products. For this purpose, by using natural materials like
algae on the beach, organic and environmentally friendly fertilizer was prepared. In
this investigation effect of Seaweed Liquid Fertilizer (SLF) of Ulva fasciata at
concentrations of 0%, 2.5%, 5%, 7.5% and 10% on some parameters of wheat
(Triticum aestivum var. chamran) has been investigated. Based on the results, above
algae can be used as a food supplement solution in the form of foliar spray at 2.5%
concentration with a significant increase in morphological and biochemical indices.
Cardiovascular diseases are considered as one of the threats to human
health, especially, in individuals with overweight. The aim of this study was to
investigate the effect of eight-week aerobic exercises in 10 to 12 years old overweight
girls. In this study, 27 overweight female student whit 10-12 years old were selected
and were randomly divided into two groups; a) training group (n=17) and b) control
group (n=10). Training group participated into the aerobic training for 8 weeks, with
70-85 percent of heart rate reserve maximum, 3 times a week and 60 minutes in each
session. The variables such as BF, BMI, WHR and VO2max, were measured in two
groups before and after the training period. The average of variables such as BF, BMI
and VO2max were significantly different between two groups (P<0.05). But the
average of WHR were not significantly different between two groups. According to
these results, aerobic exercise in 10-12 years old overweight girls, can have beneficial
effects on some cardiovascular risk factors.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

INTRODUCTION
Air is never found absolutely clean in nature.
It is indeed deteriorated every moment due to ever
increasing industrial activities, automobiles etc. The
industrialized countries are dumping lot of
materials and wastes in their immediate
environment, which is now becoming a big source
of pollution. During the past many decades, there
has been a growing awareness about the serious
hazards of atmospheric pollution to which we are
constantly exposed. Serious discussions are going
on about the effects of green house gases and
carbon gases on environmental security world wide
(Kanchev et al., 2005, Blottnitz and Curran, 2007).
The damaging effects of air pollution on vegetation
have been recognized (Treshow, 1970; Chang and
Terwilliger, 2000; Cape, 2003). Screening of plants
for their sensitivity to air pollutants is of vital
importance. Many workers like Agarwal and
Tiwari, 1997, Paulsamy et al., 2000,
Ramakrishnaiah and Somasekhar, 2003, Kannan,
2003, Rathinaswamy et al., 2005 have identified
tolerant tree species of air pollution for some
industrial cities in India.
In India, Tamil Nadu is one among the
leading states in industrial development. Kothagiri,
one among the cities gets affected by air pollution
mainly due to automobiles and agricultural
pesticides in Tamil Nadu. Since, it is one of the
important tourist places in Nilgiris, Kothagiri is
experiencing high degree of air pollution through
vehicles. In this juncture, for the control of the
effect of air pollution, an attempt has been made in
the present study at Kothagiri to identify suitable air
pollution tolerant tree species based on air pollution
tolerance index.
MATERIALS AND METHODS
The locally available tree species were
analyzed for air pollution tolerance index (APTI) by
estimating the contents of ascorbic acid,
chlorophyll, relative moisture in leaf and leaf
extract pH at monthly intervals from November
2006 to July, 2007. Leaves from tip, middle and
basal canopy of trees were collected in the forenoon
between 07.00 and 08.00 am. Care was taken for
plants under investigation with respect to exposure
of almost similar conditions for light, water, soil
and pollutants. The collected samples were
analyzed for ascorbic acid, total chlorophyll and
relative water content and leaf extract pH.
Unpolluted regions were taken 25km away from the
city which served as control. The ascorbic acid and
total chlorophyll contents were estimated
respectively by the methods of Keller and
Schwanger (1977) and MacLachlon and Zalik
(1963). Relative water content was determined by
following and the leaf extract pH was measured by
using digital pH meter.
The air pollution tolerance index (APTI) was
determined by using the following formula
proposed by Singh and Rao (1983):
APTI =
Where,
A= ascorbic acid content in leaf (mg/g); T=
total chlorophyll content in leaf (mg/g); P= leaf
extract pH and R= per cent water content of the
leaf. The sum value is divided by 10 to get the
value in reduced scale.
RESULTS AND DISCUSSION
A considerable number of 24 tree species
were analyzed in the municipal town, Kothagiri. It
was estimated that many tree species showed wide
variation in leaf chlorophyll content at the study
area. The higher chlorophyll content was prominent
in tree species like Alnus nepalensis, Callistemon
lanceolata, Cupressus cashmeriana, Ficus elastica
and Michelia champaca (Table 1). Further, it was
observed that the close proximity observed between
the individuals of tree species growing in polluted
(Kothagiri) and unpolluted nearby areas with
respect to high chlorophyll content indicates that air
pollution has no marked effect upon the synthesis
of chlorophyll pigment for these species. In the
other extreme, some species including Accia
dealbata, Pinus roxburghii, Podocarpus latifolia,
Sterculia guttata and Syzygium cumini have
contained lower amount of chlorophyll. Speading
amd Thomas (1973), Santhoskumar and Paulsamy
(2006) already reported that pollution stress
decreases the chlorophyll level in plants. However,
the other species have been drastically affected by
pollution in terms of chlorophyll production.
Varshney (1982) reported that plants appearing
green and normal at low concentration of sulphur-di
-oxide show reduced efficiency of photosynthesis.
Hence, it is known that the plants having high
chlorophyll content under field condition are
generally tolerant to air pollution.
The leaf extract pH was higher (6.5) in the
species, Ficus elastica (Table 1). In the presence of
an acidic pollutant, the leaf pH is lowered and the
decline is greater in sensitive species (Scholz and

Reck, 1977). A shift in cell sap pH towards the acid
side in the presence of an acidic pollutant might
decrease the efficiency of conversion of hexose
sugar to ascorbic acid. However, the reducing
activity of ascorbic acid is pH controlled, being
more at higher and less at lower pH. Hence, the leaf
extract pH on the higher side gives tolerance to
plants against pollution (Agarwal, 1989; Agarwal
and Tiwari, 1997).
Ascorbic acid being a strong reductant
protects chloroplast against sulphurdioxide induced
H2O2, O2ˉ and OH accumulation and also protects
the enzymes of the CO2 fixation cycle and
chlorophyll from inactivation (Tanaka et al., 1982).
Together with leaf pH it plays a significant role in
determining the SO2 sensitivity of plants
(Chaudhary and Rao, 1977). Thus plants
maintaining higher ascorbic acid level under
polluted condition are considered to be tolerant to
air pollutants. The results of the present study
revealed that the same five species of higher
chlorophyll content are also having high ascorbic
acid content in polluted regions and they are
considered to be pollution tolerants (Table 1).
The relative water content was higher for
some species such as Alnus nepalensis, Callistemon
lanceolata, Eucalyptus ficifolia, Ficus elastica,
Michelia champaca and Toona ciliata in the study
area. Relative water content is associated with
protoplasmic permeability in cells causes loss of
water and dissolved nutrients resulting in early
senescence of leaves (Masuch et al., 1988). It is
likely therefore that the tree species with high
relative water content under polluted conditions
may be tolerant to pollutants.
The obtained APTI of certain tree species
viz., Alnus nepalensis, Callistemon lanceolata,
Eucalyptus ficifolia, Ficus elastica , Michelia
champaca and Toona ciliata was higher and it was
lower in some other species like Acacia
melanoxylon, Biota orientalis, Grevillea robusta,
Jacaranda mimosifolia, Podocarpus latifolia,
Sterculia guttata, Syzgium cumini etc. (Table 1). In
addition, it is known that the pollutants released
from chemical method of pest control and
automobiles have been effectively utilized by the
tree species of higher APTI value. This is evidenced
by very narrow differences in the APTI values of
individuals of respective species between polluted
Kothagiri city and unpolluted rural areas. Different
plant species vary considerably in their
susceptibility to air pollution. The tree species with
high and low APTI can serve as tolerant and
sensitive ones respectively. Such plants can
effectively be used as indicators and pollution
scavengers (Singh and Rao, 1983; Agarwal, 1989;
Tiwari, 1991; Agarwal and Tiwari, 1997; Paulsamy
et al., 2000; Santhoskumar and Paulsamy, 2006;
Senthilkumar et al., 2008; Thanbavani et al., 2009).
Hence it is suggested that these tree species of high
APTI can be given priority for plantation
programmes in and around industrial complexes,
road sides and also in new urbanized areas so as to
reduce the effect of air pollution and makes the
environment clean for our healthy life.
