Abstract: An attempt was made to know the bioaccumulation of some organochlorine pesticides residues in shrimp (Peneus monodon) and prawn (Macrobrachium rosenbergii) by Electron Capture Detector (ECD) of Gas Chromatography during their culture with rice. A Total of six (06) sites viz. Bagerhat Sadar, Kochua, Chitolmari and Rampal Upazila of Bagerhat District as well as Keshobpur and Noapara Upazila of Jessore District were selected for this study from where the shrimp/prawn samples were collected to know the accumulation of some organochlorine pesticides named Heptachlor, DDT, Dieldrin and Endrin. The accumulation of heptachlor residue concentration was 0.016~0.309 ppm, Endrin residue was 0.073 ppm, Dieldrin residue concentration was 0.008~0.017 ppm and DDT residue concentration was not found in the sample Prawn body. In Shrimp sample, accumulation of Heptachlor residue was 0.014~0.031 ppm, Dieldrin concentration was 0.008~0.017 ppm. DDT concentration was 0.005 and Endrin residue was not detected in Prawn body. From the accumulation level of these four pesticide residues concentration in Shrimp and Prawn body, it was noticeable that Heptachlor concentration was in alarming level according to acceptable limit of EU which may cause serious health risk on human. Endrin, Dieldrin and DDT concentration were not in so harmful level in accordance with EU acceptable level. So, proper initiatives should take to inhibit the uses of all classes of hazardous pesticides and chemicals for avoiding any health hazard situation to ensure food safety.
