Abstract


The usage of toxic pesticides is harmful to the Human beings as well as aquatic and other ecosystem. Hence this study was conducted to validated analytical method for water and also determines the pesticide residue levels in lakes situated in the heart of the Hyderabad city. In this method organo chlorinated, organo phosphate pesticides synthetic pyrethroids and herbicides were analyzed on ECD and PFPD and good recoveries were obtained. Water samples collected during 2005 to 2007 from Hussain sagar and Mir Alam lakes detected with pesticides viz., HCH (0.00 4.21 ?gL-1), DDT (0.00 1.13 ?gL-1), Endosulfan (0.00 0.77 ?gL-1), heptachlor (0.00 0.128 ?gL-1), Dicofol (0.00 0-.124 ?gL-1), methyl parathion 0.00 0.43 ?gL-1), Malathion 0.00 3.121 ?gL-1), and chlorpyriphos 0.00 3.12 ?gL-1). The total residues were above Maximum Residues Levels (MRL is 0.5 ?gL-1).
