Zambia Copper Concentration

Similarly, a study by Hayumbu et al. measured respirable dust and respirable crystalline silica concentrations at two Zambian copper mines. The study reported mean concentrations for respirable dust 0.99 mg/m 3 (range 0–7.67 mg/m 3) for one mine and 0.87 mg/m 3 (range 0–6.94 mg/m 3) for another mine.

The Copperbelt Province of Zambia is generally rich in copper and therefore the soils are generally expected to have high concentration of copper. The results show the occurrence of high concentrations of heavy metals in mine wasteland substrates compared to the local forest soil (Fig. 3).
