title: Distribution and bioavailability of metals in subsidence land in a coal mine China.
abstract: Land subsidence in coal mine would change the type of soil so that it influences the distribution and bioavailability of metals. The results show that the total metal concentration was in the range from 0.41 ± 0.26 mg/kg (Cd) to 94.16 ± 12.06 mg/kg (Zn) and Cd was the serious pollution metal. In spatial, the concentration of most metals (except Sb) was highest in perennial waterlogged zone while was lowest in no waterlogged zone, which implied that the perennial waterlogged zone was a sink of metals in coal mine area. However, the bio-available fraction of metals was lowest in perennial waterlogged zone.
