The total concentration and the chemical forms of heavy metals were determined insuperficial sediments of the Cuchivero river, Venezuela, using sequential extraction andatomic absorption spectrophotometry with flame. Pollution indices were used to study thedistribution, pollution and environmental risk in the sediments. Total values ranged from,394-457 mgkg-1 Fe, 46,87-74,82 Mn, 6,45-11,92 Zn, 1,70-5,75 Ni, 0,39-3,7 Cu, 1,25-3,63Cr, 0,37-1,82 Co, 0,10-0,30 Cd y <Ld-0,20 mgkg-1 Pb. The meta...

The content of Fe, Mn, Cu, Cr, Ni, Zn, Cd and Pb in muscle tissuesof fish and crustaceans from the Unare lagoon (Lagunade Unare) in the state of Anzoátegui, Venezuela, was analyzedby flame Atomic Absorption Spectrometry. The levels of thesemetals present in suspended material of the water and in sedimentswere also determined in order to detect possible impacton the ecosystem. The mean concentrations in the water werelow (0.104-0.53 μmol/L Fe; 0.004-0.06 μmol/L Mn; 0.002-0.028μ...
