Distribution of chemical forms of mercury in sediments from abandoned ponds created during former gold mining operations in Colombia
Abstract
Total mercury (THg) and methylmercury (MeHg) were studied in sediments from 27 abandoned gold mining ponds (AGMPs) through small-scale artisanal gold mining in the district of San Juan in Chocó region of Colombia. The AGMPs were abandoned in the last century (1997) and were grouped into three distinct groups (2-6; 7-12; 13-20 years). Overall concentration (in ng g-1) pattern of THg in sediments varied from 39.06 to 1271.32 (avg. 209.57) with...
