SPECIATION OF TRACE METALS IN SEDIMENT OF A TROPICAL RIVER
نویسندگان
چکیده
Concentrations and speciation of Pb, Cu, Cr, Cd, As, Ni in sediment from New Calabar River, Nigeria were assayed. the trace metals determined using UNICAM solar 969 AAS. Speciation was done five steps sequential extractions. Results revealed that for wet dry seasons, concentrations (mg/kg) ranged 1.1E-2±1.0E-3 As to 5.17±0.04 majority bound residual fraction (F5), while Cu mostly exchangeable (F1). Overall trend indicated Cr higher F5 lower organic matter (F4). It also F4 Pb F1 F4; F4. The study has indeed provided data information on pollution status river.

Chemical speciation of trace metals in seawater: a review.
The recent development of the chemical speciation of trace metals in seawater is described. The speciation studies reveal that metal ion complexation is one of the most important processes in seawater; especially, most bioactive trace metals, such as Fe(III) and Cu, exist as complexes with ligands in dissolved organic matter. The organic ligands in seawater are characterized with metal ions sel...
متن کاملInvestigation of heavy metals accumulation in the sediment and body of carp fish in Aras River
Heavy metals are considered as the most dangerous water contaminants because of their possibility of bioaccumulation and toxic effects. This study tried to investigate the bio-availability of heavy metals in terms of Ni, Zn, Cu, Fe, Hg, Cd, and Pb in the sediment during dry seasons in Aras River basin located in Ardabil Province, north-west of Iran. Also the metal concentration in the skin and ...
