The result obtained are-Total HCH-100% samples of cold drink of different brands were found contaminated with HCH residues. In maximum sa mples γ-isomers (Lindane) were detected. The concentration was found below its MRL value (3µg/L). Residues of DDT including pp-DDT, op-DDT, pp-DDE, OP-DDE and pp DDE were found in 50% of the total samples of diffe rent brands of cold drink. pp-DDT and op-DDT were m ain contaminant. The concentration was found within the ir safe limit (1µg/L). Residues of dicofol, endosul fan and Chloropyriphos were found in 48%, 60% and 46% of the total cold drink samples of differe nt brands .
