The distribution and cumulative characteristics of heavy metals in agricultural soils caused by mining activities are different. Samples of agricultural soils and plants were collected from 4 districts according to the sources of irrigation water, that is, sewage irrigation area, clean water irrigation area, natural remediation area and contrast area. The contents of extractable fractions of Cd, Pb, Cu, Zn, and Mn, soil physical-chemical properties and heavy metal contents in plants were analyzed. The results showed that: 1) The contents of Cd, Pb, Cu and Zn are the lowest in the contrast area and highest in the sewage irrigation area, which were 1.75-10.5 times of those of clean water irrigation area and natural remediation area. The contents of Mn in all soil samples were nearly the same. 2) Significant correlations existed among Cd, Cu, Zn and Pb, while significant negative correlations existed between Mn and other 4 heavy metals. Moreover, correlation analysis indicated that soil pH played a significant role in the contents of environmental available states of the studied 5 heavy metals. Soil organic matter content and mechanical composition also affected the contents of heavy metals in soil. 3) Residual fraction was the major fraction of all the 5 heavy metals and organic matter binding fraction was relatively high in all the sampling sites. The contents of environmental available state of Cd were about 2 times those of other studied heavy metals. 4) The contents of Mn, Cu, Zn, Cd and Pb in rice were lower in clean water irrigation area than those in sewage irrigation area. The contents of Cu and Zn in rice were within the standard limit in NY861-2004, while those of Pb and Cd far exceeded the corresponding limits. 5) The heavy metals in clean water irrigation area and natural remediation area exhibited significantly lower risk of soil pollution and human health. The data will provide scientific basis in mine environmental pollution control.
