An extensive study of wastes containing mercury (Hg) released from carefully selected industrial sources in Korea was conducted. First, 89 sources associated with 21 Hg waste-producing industries were selected for investigation. The types of waste generated, the treatment methods used, the total annual amounts of waste released, and Hg concentrations of waste samples were then thoroughly identified. Two wastewater treatment sludge samples were classified as waste with high Hg concentrations (US EPA; >260 mg/kg). Based on the 156 waste samples analyzed in this study, the total annual amount of Hg released was estimated to be close to 33 t.
