Bioaccumulation of Pesticides in the Selected Group of Fishes from Chettuva Backwater, Thrissur, Kerala

In an agricultural country like India, pesticides are a major aquatic chemical pollutant. The broad class of and biological agents that damage or kill pests. There mainly three groups synthetic organic pesticides-organochlorines, organophosphates carbamates. Fishes the vulnerable biotic components as they sequester effects to higher organisms including man through food chain. this paper attempt has been made study levels pesticide residues in order elucidate status these contaminants fish meant for human consumption. Specimens were collected from Chettuva backwater Thrissur district, Kerala. Samples cleaned tap water, muscle tissues dissected, minced into smaller pieces. Quantitative analysis OCs, OPs Carbomates with Gas Chromatography. result revealed among OPs, Trizophos was detected maximum it contributed more than 50% total whereas Phorate showed least contribution. Among organochlorines pesticides, α-endosulfan endosulfan sulphate most frequently pesticides. Percentage composition also computed maximum. level carbamate residue recorded. Carbofuran pesticide. 65%
