Abstract

Environmental pollutions by pesticides of inland water have been a worldwide issue, since most of these compounds are very persistent, bio-accumulative and poisonous. Pesticides could allot to the components of the environment, such as water, sediment, and accumulate in the biota. The side effects of pesticides could be serious and chronic. In this study, we have investigated the levels of selected pesticides such as DDT (dichlorodiphenyltrichloroethane), HCH (hexachlorocyclohexane) and Endosulphan in surface waters, sediment and fish samples by gas chromatography of the Mahi river of Vadodara, India which was passed out in several periods from 8 pre-determined positions. Organochlorine pesticide (OCPs) concentration level in sediment is pointedly different from that of water and fish tissue, which had the maximum residual concentration. Detected pesticide residues are generally higher than specific limit of 0.01 g/l by USEPA for pesticides of aquatic life-cycle; therefore, possess an ecological risk to the ecosystem and consequently human health.
