Study Of New Quantification Methods Of Selected Organic Pollutants And Their Accumulation In Environmental Matrices Of Chhattisgarh

Abstract

Chhattisgarh is pre-dominantly a tribal state, where about 85 percent of the newlinepopulation depends upon agriculture with rice as the main crop. Agricultural and newlinerelated activities release vast amount of pesticides and other toxicants. Pesticides find newlinetheir way into the body tissue directly or indirectly through food chain and some of newlinethem are quite stable or have unusually long half life, further certain toxic chemicals newlineare neither fully metabolized nor quickly de-toxicated and therefore create serious newlineproblems or residue accumulation and even death. Pesticides have became a newlinenecessary evil. They are considered indispensable for pest control in agricultural newlineproduction animal husbandry, public health programmes and post harvest newlinetechnologies. However continued and at times excessive and unplanned use of newlinepesticides has resulted in high level of environmental pollution residue and even newlineproblems of toxic diseases, morbidity and mortality. As a result of indiscriminate use newlineof pesticides quality of our environment has severely deteriorated. Air, soil, rivers, newlineponds, streams, groundwater and food chain have also been affected to a great extent. newlinePesticides principally revolve round the health and environment, dangers of pesticides newlineincluding risks of manufacturers users and the public, the residues in food and threats newlineto the environment and other agricultural crops. newlineEvery year about a billion gallons of pesticide containing liquid is sprayed on to newlinefarms, orchads, market, gardens, roadside, verges etc., all over the world. Pesticides newlineuse, a critical modern input, has become an established global practice. With the newlineincreasing use of pesticides as part of the newly developing agrotechnology it was newlinerealized that a single pesticide did not completely eliminates all the species of a target pest. As a result the number might be over 1000, which includes herbicides, newlinefungicides, insecticides, rodenticides, nematicides, molluscicides etc. newlineThe number of pesticides, e.g. herbicides, insecticides, fungicides, pyrethroid newlineinsecticides etc an
