폐탄광 배수에 의해 오염된 하천의 화학적 특성과 미생물 활성
KDICical Characteristics and Microbial Activity of Streams Contaminated by The Abandoned Coal Mine Drainage

Cho, Kyoung-Suk  
  • 초록

    A survey was carried out to investigate the contamination of streams by the acid mine drainage originated from the abandoned coal mines and coal refuse piles. The physico-KDICical characteristics such as pH, sulfate and elements concentrations in the water and sediment in streams were analyzed. Microbial activity in the sediment was evaluated by measuring dehydrogenase activities. At sites contaminated by acid mine drainage, the pH of the water and sediment declined to acidic range from neutral due to the accumulation of sulfate. The dehydrogenase activity ranged from 12 to $170{\mu}g-TPF{\cdot}g-dry\;soil^{-1}{\cdot}24h^{-1}$ at the contaminated sites, whereas uncontaminated sites had activities of 1,176~4,259 ${\mu}g-TPF{\cdot}g-dry\;soil^{-1}{\cdot}24h^{-1}$ . The dehydrogenase activity was significantly affected by low pH of the sediment, indicating that high concentration of sulfate inhibited microbial activity. The concentrations of heavy metals such as Pb and Fe in contaminated sdeiment (37~46 ppm Pb; 46,000~464,000 ppm Fe) were much higher than those in the uncontaminated sediment. The concentration of Al in the contaminated water acidfied by coal mine drainage was in the range of 11 to 42 ppm. Compared with those in the uncontaminated sediment, the concentrations of Mn, Mg and Ca in contaminated sediment were low because of the leaching from soil to water by the acidfied stream water.
