  • Mine tailings, soils. stream sediments around Gubong disused mine were analyzed in order to investigate their distribution and pollution levels of heavy metals and cyanide. The average contents of As, Cd, Cu. Hg, Pb, Zn, and CN ̄ in mine tailings were 6.93$\times$$10^{3}$, 56.9, 209, 5.03, 3.25$\times$$10^{3}$, 1.89$\times$$10^{3}$, 21mg/kg respectively. The pollution indices that calculated by the tolerance level of Kloke were 42~95 and the pH values were slightly alkaline in mine tailings. The contents of heavy metals and cyanide in field soils near the mine were higher than the paddy soils. The contents of heavy metals in the stream sediment were up to that of the tailings, so contamination from the mine tailings were serious.
