Organochlorine pesticides in sediments and fish (Arius maculatus and Clarias batrachus)at the Paka River, Dungun, Terengganu

Abstract

High concentrations of organochlorine pesticides (OCPs) have been a major environmental issue. Therefore, the objectives of this study are to determine the concentrations and distributions of OCPs in sediments and fish, together with their relationships at Paka River and Lembah Sitrus, Durian Mentangau, both in Terengganu, Malaysia. The OCPs groups namely DDTs, BHCs and cyclodienes were investigated in sediment (surface) and muscle tissue (flesh) of fish (Arius maculatus and Clarias batrachus) samples at twelve sampling stations in two different seasons.
