Mine tailings from an abandoned metal mine in Korea contained high concentrations of arsenic (As) and heavy metals [e.g., As: 67,336, Fe: 137,180, Cu: 764, Pb: 3,572, and Zn: 12,420 (mg/kg)]. US EPA method 6010 was an effective method for analyzing total arsenic and heavy metals concentrations. Arsenic in the mine tailings showed a high residual fraction of 89% by a sequential extraction. In Toxicity Characteristic Leaching Procedure (TCLP) and Korean Standard Leaching Test (KSLT), leaching concentrations of arsenic and heavy metals were very low [e.g., As (mg/L): 0.4 for TCLP and 0.2 for KSLT; cf. As criteria (mg/L): 5.0 for TCLP and 1.5 for KSLT].
韩国一座废弃金属矿山的尾矿中含有高浓度的砷（As）和重金属[例如，As：67336、Fe：137180、Cu：764、Pb：3572、Zn：12420（mg/kg）]。美国环保署方法 6010 是分析总砷和重金属浓度的有效方法。尾矿中的砷通过连续提取显示出 89%的高残留分数。在毒性特征浸出程序（TCLP）和韩国标准浸出试验（KSLT）中，砷和重金属的浸出浓度非常低[例如，As（mg/L）：TCLP 为 0.4，KSLT 为 0.2；cf. As 标准（mg/L）：TCLP 为 5.0，KSLT 为 1.5]。
