Abstract :

The target of the present study was to determine and compare four heavy metal elements (Pb, Cd, Hg and As) in three Crustaceans species namely Litopenaeus Vannamei, Penaeusindicus & Penaeus monodon and three Cephalopods species namely Loligoduvaucelii, Sepia pharaonis & Octopus vulgaris, collected from fish market, Cochin coast. Kerala, India. Heavy metal concentration was determined by ICP–MS (Inductively Coupled Plasma Mass Spectrometer). Effluent from Industrial Activities reaches the wetland water and finally transferred to human being through food chain and causes toxicity. Hence these sea foods are commonly consumed and imported to other countries. It is matter of great concern to reduce such contamination. In this study,The mean concentrations (mg/kg) of toxic elements in Crustaceans and Cephalopods species were Pb: 0.1–0.58 and BDL–1.67, Cd: BDL–0.71and 0.11–2.09, Hg: BDL–0.15 and BDL–0.16, As: BDL–0.51 and BDL–2.91. In few samples, level of Pb, Cd and As except Hg was found to be exceeded the recommended limits in EU regulation (EC1881/2006).
