2017-5-28  For instance, in Ghana most natural scientific studies on impacts of gold mining on theenvironment have concentrated exclusively on measuring the levels of toxic chemicals such as arsenic,cyanide, cadmium, lead and mercury in water, soil and food crops grown in mining communities [4,7];while other studies have focused on assessing cancer and non-cancer human health risks to residentsof mining communities associated with toxic chemicals via oral and dermal contact with the toxicchemicals in polluted water [7,10–12]. On the other hand, the social-scientific studies have focused onassessing the socio-economic status of mining-dependent areas and on the socio-economic costs oreffects of mine closures and their views on future development of mines [13,14]. There appears to bevery little overlap between the two fields of research on gold mining, and there is a paucity of researchon the cumulative and integrated impacts of artisanal gold mining on host communities.
