Abstract

The purpose of this review is twofold. The first objective is to summarize OC residue levels in the waters, sediments and marine organisms - specifically fish, crustaceans, and bivalves - along the Asian coastline. The second objective is to summarize some of the possible toxilogical effects induced by OC contamination in those marine organisms and in humans.

It is important to narrow the broad list down to a select few compounds that seemed important regarding the selected region. Target compounds for this review are dichlorodiphenyltrichloroethane (DDT) and its metabolites dichlorodiphenylchloroethane (DDE) and dichlorodiphenyldichloroethane (DDD), hexachlorocyclohexane (HCH), which include its isomers (α, β, ∂, and γ (lindane)), and hexachlorobenzene (HCB). These chemicals have been used extensively in the Asian region and were found in numerous articles that focused on residual concentrations in marine organisms, bioaccumulation and/or biomagnification properties, and/or the effects they may or may not have on marine organisms and humans.
