Selenium is an essential element found naturally in the environment through weathering of rocks. It enters plants and air through dust and is released during combustion of coal and oil. Both too little and too much selenium can impact human health. It can accumulate in organisms and biomagnify up the food chain. Occupational exposure to high levels of selenium through air can cause respiratory effects. Measures are needed to reduce selenium levels to protect environmental and human health.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.
Use of Raffias’ species (Raphia spp.) and its impact on socioeconomic charact...Open Access Research Paper
Raffias’ species are used in handcrafts, constructions, food processing etc. But in Benin, any quantitative ethnobotanical study was not evaluated for their use and socioeconomic impact of uses on average income. This study investigated the importance of use of raffias’ species and the impact of socioeconomic characteristics of informants on the household income. Ethnobotany quantitative approach was used and data on use, products prices and the quantity sold were collected using a semi-structured questionnaire administered during an interview. The result showed that raffias’ species in Benin are used principally for craft (CI = 1.41 for R. hookeri and 1.68 for R. sudanica), but R. hookeri was most important for people in Guinean zone than those in soudanian and soudano-guinean zones. The frequently uses were the beds, mats, baskets and roofs. The most part of the plant used is the rachis for both species and the less used is the nut. Education level, gender and main activities were socioeconomic variable which influenced the annual income from exploitation of raffias species. The uneducated, men and farmers took more income from raffias’ species than others. Also, the development level of areas where the species are found, influence the income from their exploitations. To evaluate better the contribution of raffias’ species to regional and national gross product, it will be necessary to study the value chain of the main products, but also take into account the informant categories defined in this study regarding operators.

UNEP's presentation is utilized to address the problems facing our planet and augment them with practical and effective solutions.
A new era is emerging where human-centric solutions matter more than ever before
3. Biological Role
• Our bodies contain about 14 milligrams, and every cell in a human
body contains more than a million selenium atoms.
• Too little selenium can cause health problems, but too much is also
dangerous. In excess it is carcinogenic and teratogenic (disturbs the
development of an embryo or foetus).
4. • Low levels of selenium can end up in soils or water
through weathering of rocks.
• It will than be taken up by plants or end up in air when
it is adsorbed on fine dust particles.
• Selenium is most likely to enter the air through coal and
oil combustion, as selenium dioxide.
EFFECTS OF SELENIUM ON THE ENVIRONMENT
5. EFFECTS OF SELENIUM ON THE ENVIRONMENT
• There is evidence selenium can accumulate in the body tissues of
organisms and can than be passed up through the food chain.
• Usually this bio magnification of selenium starts when animals eat a
lot of plants that have been absorbing large amounts of selenium,
prior to digestion.
6. HEALTH EFFECTS OF SELENIUM
• Exposure to selenium through air only comes about in the
workplace usually.
• It can cause dizziness, fatigue and irritations of the mucous
membranes.
• When the exposure is extremely high, collection of fluid in the lungs
and bronchitis may occur.
9. Sources
• Man-made: waste incinerators, metal processing works, mines and
industrial facilities burning coal.
• In urban areas, the main sources are fumes from the burning of oil
fuels and dusts from industry.
• Naturally from the earth's crust and so is found in soils, natural water
bodies and sediments.
10. Stibnite
• It is a toxic antimony sulfide mineral and a source
of metalloid antimony.
• Stibnite paste has been used for thousands of
years for cosmetics to darken eyebrows and
lashes.
• The mineral was also used to make eating
utensils, causing poisoning from antimony
ingestion.
11. Antimony poisoning
• Harmful effects upon body tissues and functions of ingesting or inhaling
• Resulted from drinking acidic fruit juices containing antimony oxide
dissolved from the glaze of cheap enamelware containers.
• Toxicity can also result from repeated exposure to antimony in medications,
such as tartar emetic (antimony and potassium tartrate), used to induce
vomiting and in treatment of helminthic and fungal infestations.
12. Health effects of antimony
• Especially people that work with antimony can suffer the effects of
exposure by breathing in antimony dusts.
• Breathing in antimony that is bound to hydrogen in the gaseous phase, is
what mainly causes the health effects.
• Exposure to relatively high concentrations of antimony (9 mg/m3 of air) for
a longer period of time can cause irritation of the eyes, skin and lungs.
As the exposure continues more serious health effects may occur, such as
lung diseases, heart problems, diarrhea, severe vomiting and stomach
ulcers.
14. Highly toxic to the humans
Arsenic can exist in four valence states: –3, 0, +3 and +5
Permissible exposure limit (PEL) for arsenic is set at 10 micrograms
of inorganic arsenic per cubic meter of air (10 µg/m3), averaged over
any 8-hour period
15. Release of arsenic in the environment is a result of both manmade
and natural activity.
Arsenic enters the environment naturally through
1. Ground water (arsenic contaminated ground water pollutes
the water reservoirs i.e rivers or seas and marine
organisms…..affecting the food chain)
2. Mineral ores (through weathering of arsenic-containing
minerals and ores…… mostly of sulphide bearing
mineral deposits e.g gold and copper)
3. Geothermal processes (Arsenic is released into the air by
volcanoes)
16. The effect of Arsenic poisoning on human are as follow
Carcinogenic Effects: It causes cancers of the lung, liver, bladder,
kidney by chromosomal damage
Gastrointestinal, Hepatic, and Renal Effects
Neurologic Effects: Peripheral neuropathy(destruction of axonal
cylinders) is a common complication of arsenic poisoning
Dermal Effects: It causes hyper-pigmentation, hyperkeratosis, and
skin cancer
Respiratory Effects
Hematopoietic Effects: Anemia (decrease of red blood cell),
Leucopenia (decrease in white blood cells) and Thrombocytopenia
(decrease in platelets) are common in chronic arsenic toxicity
Reproductive Effects: Increased frequency of spontaneous
abortions and congenital malformations has been linked to arsenic
exposure
17. It cant be destroyed once enter the environment
Arsenic-contaminated environments are characterized
by limited species abundance and diversity.
Plants absorbs As fairly easily
Inorganic As in water enhances the chances of genetic
alteration in plant eating fresh water organisms i.e.
fish
When birds eat these organism they suffer from As
toxicity
19. Introduction of Copper
• Copper is distributed in nature in ores containing sulfides, arsenides,
chlorides, and carbonates
• A reddish brown ductile metal, copper is valued for its high electrical
conductivity and resistance to corrosion
• Copper exists in the +2 oxidation state
• Compounds containing Copper are Copper(II) oxide(CuO) is black,
and Copper(I) oxide (is red)
20. Sources of Copper
• Natural sources
Wind-blown dust, decaying vegetation, forest fires Also released into
waterways by natural weathering of soil and rocks
• Human activities
Mining, metal production, phosphate fertilizer production, Industrial
settings, waste disposals and effluent from sewage treatment plants.
21. Routes Of Exposures
Oral exposure
From food
Inhalation
From copper smelters and refineries and industries
Dermal contact
From air, water, and soil that contains copper
22. Natural and anthropogenic Atmosphere
Sources
Rain
Vaporization
Water Soil
(Mix with sediment)
ground water
Fish
Human Human
23. Copper toxicity
• A condition in which copper is retained and begins to build up
in the body tissues
• It Interferes with proper conversion of thyroid hormone
• It also disturbs zinc balance
• It inhibits cortisol production, and increases aldosterone
production
• As excess copper and calcium increase in the cells and tissues,
a calcium "shell" will build up

24. Symptoms(Human Beings)
Symptoms of High (Excess) Copper
• Cold hands, and/or feet
• Depression
• Dry skin
• Feeling of loss of control
• Paranoia
• Despair, suicidal feelings,
hopelessness
• Arthritis, calcium spurs
• Constipation
• Panic attacks, high anxiety
Symptoms of Copper Deficiency
• Anemia
• Fatigue
• Decrease in number of white blood cells
• Osteoporosis
• Nerve damage can cause tingling and loss of
sensation in the feet and hands
• Confusion
• Impaired Coordination
• Vitamin B12 deficiency
• Iron deficiency
• White, gray and silver hair
25. Copper and Environment
• Copper does not break because of that it can accumulate in plants and
animals
• When copper ends up in soil it strongly attaches to organic matter and
minerals
• On copper-rich soils only a limited number of plants has a chance of survival
• Copper is a serious threat to the productions of farmlands
• Copper can interrupt the activity in soils, as it negatively influences the
activity of microorganisms and earthworms
• When the soils of farmland are polluted with copper, animals will absorb
concentrations that are damaging to their health
