Chlorinated Hydrocarbons in Marine Sediments of the Baja California (Mexico)-California (USA) Border Zone

摘要

Polychlorinated biphenyls and organochlorinated pesticides are widespread on land and in aquatic environments. This is a result of their wide use during the last two decades in industry, agriculture and even health campaigns that use them to counteract diseases such as malaria. Their physicochemical properties make them very resistant to biological degradation and, thus, highly persistent (Fowler, 1990; Wesen et al, 1992; Iwate et al, 1994).
