Lead distribution in water and its association with sediment constituents of the “Barje” lake (Leskovac, Yugoslavia)

The lead concentrations in the water of the ?Barje? lake are presented for the years 1995 to 1998. Sequential extraction was applied to estimate the chemical association of lead in the sediments of the ?Barje? lake. Several lead fractions showed highly significant correlations with the corresponding...

Zusammenfassung:The lead concentrations in the water of the ?Barje? lake are presented for the years 1995 to 1998. Sequential extraction was applied to estimate the chemical association of lead in the sediments of the ?Barje? lake. Several lead fractions showed highly significant correlations with the corresponding substrate (step II: Mn-oxyhydroxides; step III: Fe-oxyhydroxides) suggesting that lead carbonates were incorporated with amorphous iron and manganese hydroxides. An explanation for this relation can be in the same anthropogenic source of these elements. nema
