Nas últimas décadas a concentração de metais-traço no ambiente tem aumentado
consideravelmente, principalmente em regiões do semi-árido que recentemente …

Sediment contamination by metals poses risks to coastal ecosystems and is considered to
be problematic to dredging operations. In Brazil, there are differences in sedimentology …

Three approaches were applied to evaluate metal contamination in 41 sediment samples
from the Santos-São Vicente Estuarine System: normalization to Al, statistical analysis and …

The crab Ucides cordatus and the red mangrove Rhizophora mangle are endemic
mangrove species and potential bio-accumulators of metals. This study quantified the …

Abstract The Baixada Santista, besides being an important estuarine system, is responsible
for most of the international trade and economic development in the region because of the …

Acid drainage influence on the water and sediment quality was investigated in a coal mining
area (southern Brazil). Mine drainage showed pH between 3.2 and 4.6 and elevated …

The structure of the benthic macrofaunal assemblages of the estuarine portion of Paraguaçu
River, NE, Brazil, and its relationship with surface sediment characteristics (trace metals …

Recent studies have shown that the effectiveness of establishing Marine Protected Areas
(MPAs) is threatened by toxic effects of contaminants. São Paulo is the most economically …

Sediment dredging impacts coastal environments by promoting the resuspension of fine
particles and remobilization of contaminants that may trigger toxic effects. In this study, we …

This study proposes a new methodology to study contamination, bioavailability and mobility
of metals (Cd, Cu, Ni, Pb, and Zn) using chemical and geostatistics approaches in marine …
