However, anthropogenic contamination through the mining of gold, burning of coal or chlorine production can cause mercury contamination of soil over large areas. Mercury can be methylated by soil organisms causing it to become mobile in the soil leading to surface water contamination or methylmercury can be taken up by plants ( Xu et al ., 2015 ).
