- ... Antifouling paint residues may contribute to high concentrations of metals in sediments. This study aims at assessing seasonal variations of labile metals (Cu, Zn, Pb, Cr and Ni) in surficial sediments (<63 µm) of port, marina and shipyard locations in southern Brazil under the influence of antifouling paints for vessels. The highest concentrations of Cu and Zn in the sediment of shipyard areas we ...

- ... The analysis of heavy metals in sediments, associated with geochronology, can identify the historical accumulation of these contaminants that occurred over time as a result of anthropogenic activities. A study was conducted at Paiva Castro Reservoir, a tropical reservoir in Brazil, to (1) establish baseline values for the metals Cd, Cr, Cu, Ni, Pb, Zn, Mn, Al and Fe; (2) investigate the history of ...
