Mercury has become a chemical of major concern in international community as recently UNEP (United Nations Environment Programme) has adopted Minamata Convention on Mercury as an international action all over the world. In this study, substance flow analysis (SFA) of mercury was performed on waste materials from five different waste and wastewater treatment facilities. Samples were collected from the sites to determine the levels of mercury. Other relevant data were obtained through the field investigations, literature review from local and global reports, and available statistics. Also, some emission rates of mercury by each site were estimated by substance flow of mercury. Data reconciliation with MFA (Material Flow Analysis) Software, STAN, was used for mercury flow in Korea by decreasing data error of this study. And, data reconciliation was applied by Least Square Method and Error Propagation Theory. Based on the results of SFA, it has found that substantial amount of sludge included mercury in a wastewater and sewage treatment facilities. Also, it has discovered a considerable amount of mercury as fly ash in a post-dust collector in an incineration facility for industrial and medical waste.
