Mercury behaviour in sediments from a sub-tropical coastal environment in SE Brazil,l concentrations of mercury were compared to sediment contents of clay-silt, organic/inorganic carbon, total hydrolyzable amino acids (THAA) and specific amino acids, total sulphur and iron. A sequential extraction was also used to clear up some questions arising from the total concentration correla

,Assessment of the heavy metal pollution in a gold “garimpo”,nd levels of metals were determined by analysing sediments and soils unaffected by mining activities, located upstream of the anthropogenic inputs. The study done in Poconé focuses on Hg, Cu, Pb, Zn, Fe and Mn. In addition, the study aims to evaluate the level of contamination in sediments, soils an

Mercury partitioning within alluvial sediments of the Carson river valley, Nevada: Implications foromstock Lode near the end of the 1800s. Detailed investigations have shown that these contaminated tailings were deposited along the Carson River Valley during a period of channel and floodplain aggradation. Following cessation of mining, incision re-exposed the historical sediment in banks of the m
