ABSTRACT- The contamination in aquatic environment, in the last decades, is undeniable. And, one of the most important source that contributed to this contamination are industrial wastewaters. The Babitonga Bay is situated in the South of Brazil, wide 7267.7 ha, and where there is a representative mangrove cenosys. This kind of ecosystem is very rich in benthic communities. For this reason, it is source of food for many fisherman′s communities and for population that lives in cities around it. Therefore, it receives daily, a great volume of several kinds of industrial effluents and domestic sawage. It is known that aquatic contaminated environment is responsible for many human health′s problems which can be generated through ingestion of water or seafood. In this sense, the study of anthropic contaminant of Babitonga Bay is important to increase the quality of life of population and, also to help to preserve this kind of ecosystem, so rich in organisms. The analysis was ingaged in identification of the principal anthropic source of contamination. Analytical speciation and quantification of heavy metals and hydrocarbons has been done in sediments, linked with the remote sensing data of suspended solids, turbidity, and chlorophyll. The results suggest that textile and metallurgical effluents are the main responsible for the low quality level of some areas of Babitonga Bay.

Key words: sediments, heavy metals, remote sensing, Babitonga Bay
