A Study on the Distributions of Heavy Metal Concentration in a Soil near Abandoned Mine
초록
This study was investigated the distributions of heavy metal concentration in a soil near abandoned mine in Chung thong Nam Do. The abandoned mines were Gubong gold mine and Sinsung coal mine. The results were as follows : 1) The concentration of As and Pb in Gubong mine were 309.2mg/kg and 1163.5mg/kg, that is exceeded the countermeasure criteria. Cadmium concentration was 14.70mg/kg, that is exceeded anxiety criteria. But all items in Sinsung coal mine was detected below criteria. 2) The heavy metals contamination of riverbed soil by gold mine showed higher than coal mine. 3) The heavy metals contamination in the vicinal paddy and dry field soil area was higher than other mine. Arsenic concentration was 29.29mg/kg, that is exceeded the anxiety criteria as 10.22mg/kg.
