This study examines the ecotoxicological effects of wastes and fertilizers on various target organisms. Experiments were conducted on earthworms, ornamental fish (tiger barb), marigold plants, and capsicum plants. The earthworm experiment observed mortality and reproduction under different fly ash concentrations. The fish experiment observed mortality under different concentrations of domestic wastewater. The marigold experiment observed growth under different fertilizer doses. The capsicum experiment observed growth under different fly ash proportions. The results found that fly ash up to 25% and wastewater up to 7ml/L had minimal effects, but higher concentrations inhibited growth or increased mortality. Excessive fertilizers also inhibited plant growth and soil cultivability
Ecotoxicology is the study of the effects of toxic chemicals on biological organisms, especially at the population, community, ecosystem, and biosphere levels.
Ecotoxicology is the science devoted to the study of the adverse effects of chemicals on ecosystems structure, functions, and biodiversity. It is a modern discipline, just developed during the last four decades, directly associated to the need to identify, predict, control, and minimize the negative environmental consequences of the recent human industrial development. Ecotoxicology has always been connected to toxicology, and is in part an extension of human/veterinary toxicology to the investigation of effects on wildlife. In parallel, it also linked ecotoxicology to ecology, from both conceptual and methodological viewpoints.
Toxicology
is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants.

Dr. Walter Crinnion, one of the leading experts on environmental medicine and toxicology, shares his observations on the toxic burden we bear in modern society.
Toxicology is the branch of science that deals with nature, effects, and detection of poison. The degree to which a substance can harm an organism is called toxicity. The types of toxicity depending upon the time of exposure of the toxicant have been described.
In order to assessing whether algae can reduce the pollution concentration of the effluents by
absorbing the nutrients, it is found that effluents can effectively be treated by employing algal organisisms such
as Oscillatoria and Stigeoclonium species and these organisms are frequently found in the polluted waters and
they were recorded as pollution tolerant forms. In the laboratory procedures out of the several media tested
Modified CHU No. 10 medium was found to be quite suitable for both the test organisms. It was found that up to
87% and 85% of phosphate uptake was achieved by Oscillatoria and Stigeoclonium respectively with 13% and
16% increase of D.O. in the effluents by the tenth day. In case of organic matter Oscillatoria removed 73% and
Stigeoclonium 70% up to tenth day

Dissertation ppt biostimulation- a potential practice for wastewater treaat...Sumer Pankaj
Phycoremediation is a green technology that supports the direct use of living green microalgae for in situ, or in place removal, degradation, of contaminants in soils, sludge, sediments, surface water and ground waters by the mechanisms of bio-transformation, bio-accumulation, bio-concentration, bio-sparging.
It can be said by the current study that microalgae has a great potential for the treatment of industrial and municipal wastewaters as compared to the chemical treatments available commercially. Biological systems are much more efficient in cleaning the excess nutrients from the waste water followed by generation of valuable biomass which can be applied in the food, fertilizer, energy production as use of inorganic chemicals like lime and ferrous sulphate generates huge amount of sludge in textile industries, but on the other hand static anaerobic treatment using acclimatized MLSS gives better colour reduction with zero sludge generation. Microalgal cells can be used in free form to treat waste waters containing high C.O.D., high ammonical nitrogen and high TDS. It not only provides a better reduction of chemicals from wastewaters but it also helps to reduce the operational cost of ETP. Microalgaes not only helps to remediate industrial waste waters but also to treat sweage water and to restore natural water bodies like lakes and ponds. As they are active in remediating the chemicals but also it shows an antagonistic effect against some pathogenic germs like total coliforms and fecal coliforms.
These microalgal cells can also be combined with bacterial biomass of activated sludge process to develop an Algal-Bacterial consortium (ALBA) for better enhancement in the reduction of chemicals from the wastewaters as this symbiotic relation of algae and bacteria provides high satiability of the microalgae along with MLSS and faceable in terms of price and economy for instance the bacterial biomass provides carbon dioxide to algal cells for photosynthesis and in return the bacteria acquires oxygen from algae. The harvested biomass from the ETP’s can be used as bio-fertilizers as it consists of appropriate ratio of vital macro and micro nutrients like N,P,K etc. which enhance the growth of plantlets. It can also be used as aqua feeds for shrimps, fishes and molluscs. Furthermore these microlgal cells are non-toxic in the environment as it becomes a part of food chain and do not cause eutrophication. Therefore, micro-algal based treatment is most suitable for the treating the waste waters and restoring the natural water bodies as compared to other chemical treatments.

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.

ABSTRACT- Comparative toxicity of Nerium indicum latex powder (NILP) was studied against two common predatory and weed fishes of different body size in laboratory condition and cemented and muddy pond. LC50 of NILP for predatory fish Channa punctatus was 2.13 mg/L, 7.80 mg/L and 19.26 mg/L to small size, middle size and large size fish respectively in laboratory condition after 24 h exposure periods. Similar trends were also observed in case of cemented and muddy ponds but doses were 1-4 times higher than laboratory conditions. Similar trend of result was also observed against weed fish Mystus mystus. No further mortality was observed beyond 24 h in all set of experiments suggested fast degradation of the toxicant in water.

Study and prediction of persistent organochlorine and organophosphorous pesti...iosrjce
The indiscriminate use of toxic pesticides had created an environment that without this poison the
plant life is unfruitful leading to the farmer’s life miserable. For several years, this phenomenon was continuing
and the ecosystem is protecting the environment and the life of human being from high risk of toxicity. But, how
long it will continue or weather a paradigm change in the agricultural field is required? With this objective a
field study was conducted in the cardamom plantations of Idukki district in South India to estimate and predict
the persistence of pesticide residue in the soil environment. It is observed that residues of endosulfan, DDT and
organophosphorous pesticides were present in soil samples at 31.6 %, 29 % and 21 % respectively. The present
study gives a prediction of the concentration of persistent pesticide residues in the soil if the present dose and
frequency of application is continued. The study also highlighted the adsorption capacity of soil in the study
area and low water solubility of pesticides used in cardamom plantations which is referred as partition
coefficient. The soil properties such as pH, organic content and microbial concentration which determine the
fate of degradation of pesticides and formation of its metabolites are also been discussed in this context. Based
on the observations and analysis, it is concluded that the formation of degradation products and bound residues
decrease at higher concentration of pesticide applications but the concentration of persistent pesticides
increases and the biodegradation reduced in such cases due to bound residues and reduced biological activity.
The predicted values on multiple applications where the concentrations in soil may build up and reach a
plateau, are 2.559,0.2559, 1.7324 and 0.659 mgKg-1
in the case of endosulfan, DDT, organophosphorous and
total pesticides respectively.

A preliminary study on the toxic potentials of shea butter effluent using Cla...IOSR Journals
This study was conducted purposely to evaluate the effects of shea butter effluent (SBE) on the
freshwater inhabitant using Clarias gariepinus as a biological model. A prominent Local factory of shea butter
at Tede, ATISBO Local Government was chosen because the effluent flows directly into a near-by stream that
ends up at a popular Dam in the Local Government on which more than 120,000 people depend for domestic
use.Static bioassay was conducted to determine the LC50 of shea butter effluent to Clarias gariepinus. Ten fishes
each were exposed to 0.05, 0.06, 0.07, 0.08, and 0.09ppt (lethal concentration) of SBE in separate water plastic
bowl of (40cmX29cmX28cm) of 60litres capacity.The lethal Concentration (LC50) value of SBE was 0.057ppt for
96hrs of exposure. Total mortality occurred in the concentrations of 0.08 and 0.09ppt within 24hours of
exposure period. Behavioural reactions exhibited by the fish include erratic movement, air gulping, loss of
reflex, molting, barbell deformation, hemorrhage, and excessive mucus secretion in fish exposed to higher
concentration of shea butter effluent.
The appreciable increase in the mean value of heavy metal, such as Manganese, Nickel, Cadmium,
Zinc, Copper and Lead revealed that the increase in the concentration of shea butter effluent leads to
bioaccumulation of the aforementioned heavy metals in the test organisms. The values for all the metals exceed
the permissible Criteria of the national and international regulatory body. Therefore, Shea butter effluent is
highly toxic to freshwater fishes, its discharged directly into water bodies, new fish farms or in areas close to
aquatic environment should not be encouraged.
— 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.
Two of the charter members of The Long Island Clean Water Partnership, The Citizen's Campaign For The Environment, and The Group For The East End, offer this overview of the state of Long Island's waters -- what is polluting them and what we can do about it. The CCE's Adrienne Esposito and the GFTEE by Bob DeLuca.
Long Island gets its drinking water from the ground. Whatever we do on the surface eventually makes it into the aquifer, and into our drinking water, our rivers and bays.
The largest issue is nitrates from septic tanks, from the 200+ small sewage treatment plants, and from fertilizer, both residential and commercial leaching into the ground water, and then to our bays, where they trigger massive algal blooms -- brown tide, red tide, rust tide, blue green algae. These blooms have already destroyed much of our bay's habitats, resulting in a collapse of the shellfish and finfish population. To reverse this situation, we must impose much stricter limits on how much nitrogen can enter into our ground water from the plants, farms, and from the 500,000 septic tanks that dot Long Island.
Another major threat to Long Island water is VOCS (volatile organic chemicals). While there are 254 superfund sites on Long Island, the largest source of these VOCs are household products -- cleaners, paint strippers, aerosols. 100,000 tons of household hazardous waste is disposed of improperly every year in New York.
A further threat is the 117 pesticides now found in our drinking water. Even when banned, they remain in our environment for decades.
Finally, the improper disposal of household pharmaceuticals means that these drugs are entering into our ecosystem, with effects unknown. We must stop flushing or throwing out unused prescriptions, but dispose of them only at designated county locations.
In all, there are a number of things we can do now to help LI become sustainable for future generations: Push for new technologies and new policies that would limit nitrogenous waste from our septic and sewer systems. Stop using high nitrogen lawn and agricultural fertilizers. Dispose of your household waste properly. Any chemical you use at home will end up in the ground water unless disposed of properly. Don't pour oils, grease, and chemicals down the drain. Use green, friendly home cleaning products.
Finally, since the major contributor to Long Island's water problems has been overdevelopment (without the requisite infrastructure to support it), we need to protect what green spaces we have left.
It is a wonderfull ppt for the deleterious impact of algae. There are no such type of ppt. It is prepare by myself by the help for books and research papers.
Microbial Decolorization of Leather Dye Effluentijtsrd
As we know 71% of Earths Surface is covered with water. Water is one of the most essential element for the persistence of life on this planet. Pure and contamination free water is the dire necessity of every living being present on Earth but today water pollution has posed great threat to the existence of life. The discharge of effluents from various industries into the water bodies are mainly responsible for water pollution specially effluents from leather industry are the most contaminating as along with the harmful chemicals they contain organic matter as well. The dyes disposed by the leather industry are the most harmful for the environment. The conventional physicochemical methods used for the treatment of leather dyes in the contaminated water i.e. coagulation, precipitation, oxidation etc have disadvantages and limitations. This study presents microbial decolorization of leather dye effluents from Shigella sp. isolated from effluent samples collected from leather industry. Different parameters such as temperature and pH were optimized for decolorization of Methylene Blue, Crystal Violet, EosinYellow, Safranine dyes by using bacterial isolates. Optimum temperature for decolorization was observed to be 300c, the optimum pH range for decolorization was found to be from pH6-pH8. All the samples were incubated at 30-°C 150 rpm. The decolorization was measured as decrease in absorbance maxima at 663 nm, 590 nm, 518nm, 530 nm for mehtylene blue, crystal violet, eosin yellow, safranine respectively.

DEFINITION:
It is defined as "the branch of toxicology” concerned with the study of toxic effects, caused by natural or synthetic
pollutants, to the constituents of ecosystems, animal (including human), vegetable and microbial, in an integral
context.
OBJECTIVE AND SCOPE OF STUDY:
The objective of the work is to study the ecotoxicology by conducting bioassays on Earthworm lubricous,
Ornamental Aquarium fish Tiger Barb and Marigold plants
• To observe the mortality and increase in population of earthworms
• To observe the mortality of fish tiger barb in different proportion or percentage of domestic waste water in
water.
• To observe the growth of Marigold plants in different doses of fertilizers.
• To observe the growth of capsicum plant in different proportion or percentage of fly ash
4. LITERATURE REVIEW
• FOR EARTHWORM
Most published ecotoxicological studies on earthworms are focussed on metals (Lowe and butt,2007)while the
effects of pesticides have been less studied.In the scientific literature,most studies on the effects of pesticides
on earthworms were made in the 1980 ‘s.This is the case with many studies on carbofuran(Anton, et
al,1993;Ruppel and Laughlin,1977),benomyl(Stringer and Wright,1976;Wright 1977) .
• FOR FISH
A number of chracteristics make fishes excellent models for toxicological research especially for the
contaminants which are likely to exert their impact on aquatic systems(LAW,2003;DE LA TORRE et al,2010).thus
according to DE LA TORRE et al,(2005) monitoring sentinel fish species is widely used to access the degree of
bioaccumulation of pollutants and the effects on health status
• FOR MARIGOLD AND CHILLI PLANT
As human activity impacts upon the environment on contamination issues are becoming increasingly common
(Fernandes and Henriques ,1991).in Australia there are many documented cases of flyash toxicity including in
mining (Richards et al,1996)and agriculture(Grasmanis and leeper,1966).Sources of metals in soil from
agricultural example fertilizers ,sewage sludge and animal waste used as fertilizers pesticide and irrigation
water agriculture(Grasmanis and leeper,1966)(Reddy et al,1995).

FINAL SETUP AND OBSERVATIONS:-
7. ANALYSIS :-
Mainly mortality and reproduction rate of earthworm were observed at regular intervals.
Then it was compared with natural condition (no fly ash) and its deviation was analysed.
RESULT :-
From experiment 1:- It is recommended that while the fly ash is disposed off from the industries and plants,the
concentration must be taken into concern and a concentation of FE 25 can be taken as a limit because this
amount of toxicity will not affect the biology of earthworms.

10. ANALYSIS
The physical and chemical properties of waste water was tested .This was compared with the natural
condition of fish . The mortality rate was observed at different sample condition. .
RESULTS
From above observations, it is found that Tiger Barb is resistant to concentration of 5-7 ml domestic
waste water in 620 ml of standard water and if concentration of waste water is exceeded, there is
loss of life. So while disposing waste water, in river it should have required to be diluted in sucha a
way to get required dilutions or should be treated properly before discharging in to the river to save
the aquatic life.
