Resumo: 	The aim of this work is to study the input, transfer and distribution processes of chlorinated insecticides (lindane, DDT) and PCB residues in a semi-closed coastal marine environment. Measurements are made in sea water, rain water and sediment samples. Distribution coefficients between sea water and sediment are determined for several organochlorine insecticide and PCB compounds. The results show an important transfer of chlorinated residues from the atmosphere to the marine environment. The highest residue levels in the sediments are observed near other urban and industrial pollution sources. Analyses of mussels show that this mollusc can be used as a biological indicator of sea water pollution. Concentration factors are determined for lindane, DDTcompounds and PCBs. The contamination of marine worms (polychaetes) is studied in relation to the contamination of sediments. The ranges of organochlorine residue levels in sea water, rain, sediments, mussels and marine worms are summarized.
