Mercury fractionation in stream sediments from the Quadrilátero Ferrífero gold mining region, Minas Gerais State, Brazil
(Environmental Monitoring and Assessment, 2018)
Distribution of Cr, Ni, Cu, Cd and Pb in different molecular size of humic fractions extracted from water and sediment samples collected at Anhumas reservoir - Araraquara/SP
(Editora Unesp, 2002-01-01)
In this work was studied the distribution of Cr, Ni, Cu, Cd and Pb in humic fractions with different molecular size. The HS were extracted from waters (AHS), surface sediments (HESS), interface water sediment (HSIS) and ...

Seasonal and spatial variation of trace elements in sediments of three chilean basins
(Sociedad Chilena de Química, 2020)
Total concentrations of trace elements can provide fundamental information on the sediment contamination levels of the pollution indexes and the quality guidelines for sediment risk assessment. However, this information ...
Metal fractionation in the sediment of a constructed wetland for industrial wastewater treatment
(Elsevier Science, 2011-09)
A free water surface wetland was built in 2002 to treat wastewater from a tool factory containing metals (Cr, Ni, Zn and Fe), nutrients and organic matter. Until 2006, the last reported period, the wetland retained metals ...
Fracionamento químico do fósforo no sedimento dos reservatórios de gargalheiras e carnaúba, localizados na Região Tropical Semiárida
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Ambiental, 2021-04-28)
Knowing the chemical composition of the sediment in order to determine the mobile fractions of phosphorus (P) is an essential measure in the recovery of eutrophic lakes. The P accumulated in the sediment can be released ...
P distribution in different sediment fraction of a constructed wetland
(IWA Publishing, 2011-01)
The aim of this work was to study the accumulation and fractionation of P in the inlet and outlet sediment of a constructed wetland for the wastewater treatment of a metallurgic plant in Argentina. It was important to ...
Assessment of geochemical mobility of metals in surface sediments of the Santa Rosalía mining region, western Gulf of California
(Archives of Environmental Contamination and Toxicology, 2011)
To asses the geomobility of cadmium, copper, iron, manganese, nickel, lead, and zinc in marine sediments near the Santa Rosalía copper smelter, which is located on the eastern coast of the Baja California Peninsula, ...
Spatial and temporal patterns in reef sediment accumulation and composition, southwestern insular shelf of Puerto Rico
(Caribbean Journal of Science, Vol. 45, No. 2-3, 138-150, 2009, 2014)
