The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines No...

In regions affected by artisanal and small-scale gold mining (ASGM), the inhalation of mercury vapor and the ingestion of fish contaminated with this metal constitute the main sources of mercury contamination that affect human health. Nevertheless, according to the World Health Organization, another source of contamination is polluted water. Although mercury in freshwater is usually found in ve...

The Government of Ghana prohibited Artisanal and Small-Scale Mining (ASM) operations from 2017 to 2018 as part its strategy address the socio-environmental issues caused by illegal mining activities, also referred “galamsey” operations. This study assessed trend in water quality raw abstracted at Konongo Water Treatment Plant (WTP) for treatment before after implementing ban on main source WTP ...

CONTEXT Mercury exposure has been described among small-scale gold mining communities in developing countries, but reports of inhalational mercury toxicity among home gold extractors in the US remain uncommon. OBJECTIVE We sought to identify inhalational mercury exposures and toxicity among artisanal gold extractors. METHODS This is an observational case series of a single Poison Center dat...

The rapid expansion of the artisanal and small-scale gold mining (ASGM) industry in developing countries has marginalized the local communities in poverty, and resulted in occupational exposure to mercury via the gold extraction process. We investigated the mercury exposure of the mining workers lived inside and outside the mining area. Based on the occupations of the contributors, the hair sam...
