Levels of Organochlorine and Organophosphorus Pesticide Residues in Water and Soil of Musi River Belt Area Hyderabad, India

摘要

A study was conducted to estimate residues of certain pesticides of organochlorines viz., dichlorodiphenyltrichloroethane (e.g., o,p'-dichlorodiphenyldichloroethylene, o,p'-dichlorodiphenyldichloroethane, p,p'-dichlorodiphenyltrichloroethane and o,p'-dichlorodiphenyltrichloroethane), dicofol, α-, β-, γ-, δ-hexachlorocyclohexane, cyclodiene compounds (aldrin, endosulfan sulphate and heptachlor) and organophosphates (dichlorovas, phorate, dimetheoate, methyl-chlorpyrifos, methyl-parathion, fenitrothion, chlorpyrifos, quinolphos, profenophos, ethion and phosalone) in water and soil samples collected from six zones of Musi river belt area Hyderabad, to evaluate the pollution level of Musi river. The river belt was divided in to six zones. Organophosphorus pesticide residues quinolphos was found in water and soil samples collected from zone 2, 3,4 and 5, Ethion residues were found in water and soil samples collected from zone 2, 3,4 and 6. Whereas soil samples collected from zone 1 showed residues of p,p'-dichlorodiphenyldichloroethylene, o,p'-dichloro-diphenyldichloroethane, p,p'-dichlorodiphenyltrichloroethane, o,p'-dichlorodiphenyltrichloroetnane, total dichlorodiphenyltrichloroethane and 8 hexachlorocyclohexane. The residues of all other organochlorine, cyclodienes and organophosphorus pesticides were below detection level in the water and soil samples collected from all six zones.
