Geochemical speciation and risk assessment of metals in sediments of the Lobo-Broa Reservoir, Brazil

Purpose Brazilian sediment quality criteria were established based on pseudo-total metal contents, which is not suitable to determine their bioavailability and the ecological risk for aquatic biota. Therefore, the geochemical speciation of five metals (Cu, Fe, Ni, Pb and Zn) was determined to assess...
