Resumo
The Santos estuary system is an intricate pattern of tidal channels and small rivers originating from the adjacent
Pre-Cambrian slopes. These two major estuaries share a common area in the upper portion of the region which
interacts with each other. The largest harbor in Latin America is located at the eastern outlet of the Santos
estuary. This intricate and sensitive ecosystem is highly susceptible to human impact from industrial activities,
urban sewage and polluted solid wastes disposal. Due to its high vulnerability CETESB (Environmental Control
Agency of the São Paulo State) sporadically monitors the contamination levels of water, sediment and marine
organisms in this region. The present study reports results concerning the distribution of some major, trace and
rare earth elements in the Santos estuarine marine sediments. Thirty two bottom sediment samples (SS0601 to
SS0616 (summer) and SW0601 to SW0616 (winter) were collected in this estuary, including regions of Sao
Vicente, Santos, Cubatao and Vicente de Carvalho, by a vanVeen sampler in the summer and winter of 2006.
Multielementar analysis was carried out by instrumental neutron activation analysis (INAA). The concentration
values obtained for As and metals Cr and Zn in the sediment samples were compared to Canadian Council of
Minister of the Environment (CCME) oriented values (TEL and PEL values) and are adopted by CETESB.
