  • Human mercury exposure associated with small-scale gold

    PURPOSE: In Burkina Faso, gold ore is one of the main sources of income for an important part of the active population. Artisan gold miners use mercury in the extraction, a toxic metal whose human health risks are well known. The aim of the present study was to assess mercury exposure as well as to understand the exposure determinants of gold miners in Burkinabe small-scale mines. METHODS:

  • Study on Artisanal and Small-Scale Mining in Mali

    Study on Artisanal and Small-Scale Mining in Mali 5 In Mali, gold-washing activities increased considerably from the 1980s, following drought conditions, which encouraged deprived populations to rush to this activity. Another factor which favoured the development of small-scale mining is liberalization of trade and the increase in the gold price, discovery of new easily exploitable sources
