Differences in the bioaccessibility of metals/metalloids in soils from mining and smelting areas (Copperbelt, Zambia)

Original language description

Differences in the total and bioaccessible concentrations of As and metals (Co, Cu, Pb, Zn) in topsoils (n = 107) from the mining and smelting areas in the Zambian Copperbelt were evaluated. The mean total concentrations of metals and As in topsoils weregenerally 2 to 7x higher in the smelting area, indicating significantly higher effect of smelter dust fallout on the degree of topsoil contamination. The contaminant bioaccessibility was tested by an US EPA-adopted in vitro method using a simulating gastric fluid containing a 0.4 M solution of glycine adjusted to pH 1.5 by HCl. Higher bioaccessibilities in the smelter area were observed for As and Pb, attaining 100% of the total metal/metalloid concentration. The maximum bioaccessibilities of As and Pbin the mining area were 84% and 81%, respectively. The ranges, mean and median bioaccessibilities of Co, Cu and Zn were similar for the two areas. The maximum bioaccessibilities of Co, Cu and Zn were 58-65%, 80-83% and 79-83%, respective
