Mercury in soil profiles from metal mining and smelting areas in Namibia and Zambia: distribution and potential sources
2015
Abstrakt
Based on measurements of total Hg in soils from the mining/smelting areas in Namibia and Zambia, only one fourth of the samples exceeded geochemical anomaly thresholds, and they indicated a relatively low level of Hg pollution. Elevated Hg concentrations were only observed in topsoils in the immediate vicinities of mine tailings and active smelters.
Constructed regression models were found to be useful for prediction of Hg concentrations at both of the regions studied.
