ABSTRACT
This paper examines the amount of bioavailable Zn, Cd, and Pb in dust samples derived from a zinclead
smelter by means of single-stage extraction analysis. The efficiency of three extractants (NH4OAc, CaCl2,
and H2O) was compared with respect to their efficiency toward bioaccessible (exchangeable) metals fraction.
The highest amount of metals was NH4OAc extractable, indicating that the acetate-soluble fraction was a prevailing
form in the analyzed dust and probably associated with the presence of metals in conjunction with soluble
sulfates (ZnSO4, PbSO4). The largest amount of bioavailable Zn, Pb, and Cd was extracted from the finest
dust particles, considered most dangerous for human health.
