摘要： Toxicity heavy metals in soil to ecological system were determined by chemical associations. It is significant to identify the distribution of heavy metals in arable land soil, due to the reflection of the bioavailability of heavy metals to crops, especially to the area of high anthropogenic heavy metals input. Sequential extraction procedures were applied to define As and Cd into six fractions, including water soluble (WS), exchangeable (EX), carbonate-bound (AC), Fe & Mn oxided-bound (OX) and residual (RES), in arable land soil of iron deposit area. The arable land soil of mining area was contaminated by As and Cd either or both, the average concentrations of As and Cd were 59.44 and 1.403 mg kg(-1), respectively. The ratio of residual fraction was the topped among the six fractions of these two contaminants The total ratio of liable fractions (AC, OX, OC) of As and Cd were 11.8% and 27.1%, and it was mainly determined by the processes of weathering of soil parent materials. The fractions of WS and EX in soil were related to the anthropogenic input of them.
