Abstract: Water pollution through pesticides residues and their accumulation in different tissue of aquatic animals and crops has become a real threat to human and other animals on earth. OCP’s are found cause health risks including cancer. The current study focuses on assessing the Organochloride contamination in the fish tissue (Channa.sp.) from Cauvery River, near Degganahalli area of Mysore district. Fish samples were collected from the sample site and processed following FSSAI test method using GCMS/MS. Hazard Quotient was calculated for a sample size of 384 using EDI and ADI. Concentration levels of pesticides were in the order Dieldrin> Aldrin> γ-HCH>β HCH. Corresponding concentrations of pesticides are 7.73 ± 0.94 > 1.07 ± 0.15> 0.08 ± 0.03 > 0.06 ± 0.03 respectively. Hazard quotient of dieldrin is significant with a Mean± SD value of 0.05 ± 0.03 followed by Aldrin,0.00662 ± 0.00441, γ-HCH, 0.00050 ± 0.00033 and β-HCH, 0.00037 ± 0.00025 respectively. Pesticide levels in the fish are found to be below permissible limits across all seasons od study period. Hazard quotient also falls under low risk level. Detection of Aldrin and dieldrin in the current study signifies the presences of POPs in the environment.
