Analysis of pesticides residues of Rawal and Simly lakes.

Abstract

Water samples were collected from the locations of Rawal and Simly lakes. Analysis of pesticide residues in water samples was done GC/ECD through Turbochrome hardware/software system. From the collected samples, 21 pesticides were analyzed and categorized in organophosphates, organochlorines and pyrethroids. In Rawal Lake samples average concentration of fenitrothion, 2, 4-DDT and diazinone was higher while in Simly Lake, the average concentration of 2, 4-DDT, diazinone and 4, 4-DDT was higher. The benefit of the study is awareness of general public about the risk of pesticides contaminating water, the toxicity of pesticides that have the potential to enter the aquatic system and the discussion of possible consequences of pesticide bioaccumulation of the food chain.
