Abstract | Polychlorinated biphenyls (PCBs), organochlorine pesticides and their persistent metabolites were identified in epibenthic animals from the estuaries of the rivers Brantas and Solo and from Strait Madura, Strait Bali and the Java Sea in July and November 1984. Samples of different phyla showed similar general geographical trends for the compounds investigated. Contamination with p,p'-DDE was of major importance in the river Porong, a distributary of the Brantas river system. Increased concentrations of PCBs were found near Surabaya. In Strait Madura, p,p'-DDE and PCBs were increased only in animals from the western part. Therefore the dispersion of the contaminants in biota appeared to be determined by the residual currents caused by the SE trade winds prevailing in both periods of sampling (July and November 1984). Generally no differences existed between the two sampling periods, except in the Java Sea, where PCBs were only detected during the November cruise. Compared to the animals from Strait Madura, the PCB patterns showed increased contributions of tri- and tetrachlorobiphenyls. This could not be related to differences in PCB-patterns of water or suspended particles. The compounds QCB, HCB, α -HCH, β -HCH, o,p'-DDD, methoxychlor and several cyclodienes were generally below detection limits. |
