Abstract : Industrial effluents keep a wide variety of both organic and inorganic pollutants from breweries, tanneries, sugar mills etc. The pollutants include oil, greases, plastic, metallic waste, phenols, toxins, acids, salts, dyes, cyanides, DDT etc. Na, Cu, Cr, Cd, Hg, Pb, etc are the heavy metal effluents discharged from the industries. Apart from the above there are two chief physical pollutants – Thermal pollutants and nuclear pollutants.
These are likely to accumulate in the biota of food chain and get transformed into toxicants. These toxicants after their release into environment contaminate out food, water and air. The intake and uptake of these toxicants occur in different ways by plants and animals and result into serious health hazards. These are negative impacts of modern agriculture and industrialization. Nearly 80% of the world’s diseases, particularly in developing world can be linked with water. About 15 lakh children die of these diseases in pre school group (1982 citizen report). The control measures in the light of environmental and ecological perspective is not only the scientific but socio economic issues too, which are described by the author in control measures.
