Abstract 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.

韩国多源排放含汞废物调查

摘要 对韩国精心挑选的工业来源释放的含汞 (Hg) 废物进行了广泛研究。首先，选择与21个汞废物产生行业相关的89个来源进行调查。然后彻底确定产生的废物类型、使用的处理方法、每年排放的废物总量和废物样本的汞浓度。两个废水处理污泥样品被归类为高汞浓度废物（美国环保署；>260 毫克/千克）。根据本研究中分析的 156 个废物样本，估计每年释放的汞总量接近 33 吨。
