“Major studies on the effects of mercury have been done in Zimbabwe and these include the Global Mercury Project, which was done from 2002 to 2007 and the 2015 diagnostic report on environmental health implication of mercury in artisanal small scale gold mining in Zimbabwe,” Mapako said.
He said on average, over 50 tonnes of mercury is used annually in gold processing, adding that studies on the environmental and human health assessments showed that gold stamp milling centres were the main centres of mercury pollution.
