On the Coastal zone, human occupation and economic activities have been considered the major source of contaminants to aquatic environment, particularly the sediments. Ecotoxicological bioassays are useful to assess the effect of such contaminants to the biota. In Brazil, bioassays has been used for scientific, regulatory and monitoring purposes, being important components of environmental quality management. In addition, the creation of legally protected areas is a tool for environmental management, and the São Paulo State recently established a Marine Protected Area on the north coast (APAMLN), which is divided into 3 sectors. The Maembipe sector is subject to conflicts in water use, due to different activities such the presence of oil terminal, harbors, marinas and sewage discharges in the São Sebastião channel. In this study, sediment quality of some sites within Maembipe sector will be assessed, by using sedimentological analysis and ecotoxicological bioassays with three organisms (Tisbe biminiensis, Lytechinus variegatus e Tiburonella viscana). Toxicity will be observed by statistical approaches and will provide first data for this sector, because most studies focused only in São Sebastião channel. The results will represent an important subside to this MPA, in special to provide information on impacts and threats to this area, which are required to allow the achieving of conservation objectives and success for the management.
