oai:localhost:PNK-87342023-08-07T08:38:01Z Artisanal gold mining in Kakamega and Vihiga counties, Kenya: potential human exposure and health risk Ondayo, Maureene Auma Watts, Michael J. Hamilton, Elliott M. ASGM USEPA CC-BY Artisanal and small-scale gold mining (ASGM) represents 20% of gold supply and 90% of gold mining workforce globally, which operates in highly informal setups. Pollutants from mined ores and chemicals introduced during gold processing pose occupational and inadvertent health risks to the extent that has not been well elucidated in Africa. Trace and major elements were analysed using inductively coupled plasma mass spectrometry in soil, sediment and water samples from 19 ASGM villages in Kakamega and Vihiga counties. Associated health risks for residents and ASGM workers were assessed. This paper focuses on As, Cd, Cr, Hg, Ni and Pb for which 96% of soil samples from mining and ore processing sites had As concentrations up to 7937 times higher than the US EPA 12 mg kg−1 standard for residential soils. Soil Cr, Hg and Ni concentrations in 98%, 49% and 68% of the samples exceeded respective USEPA and CCME standards, with 1–72% bioaccessibility. 2023-08-07T08:38:01Z 2023-08-07T08:38:01Z 2023 Book https://link.springer.com/article/10.1007/s10653-023-01647-z https://dlib.phenikaa-uni.edu.vn/handle/PNK/8734 en application/pdf Springer |
