Abstract:
      Contents of heavy metals both in soil and rice samples from a Cu-Pb-Zn polymetallic mining area were analyzed. Pollution degree and distribution of heavy metals in soil of this mining area as well as pollution of heavy metals in typical rice samples were studied. The results show that soil environmental quality in Cu-Pb-Zn polymetallic mining area is generally good. Heavy metal pollution in soil is concentrated around concentration plant, and main pollution elements are Cd and Cu, pollution degree of which is mainly in light level. Cumulative degree of Cd element is relatively high. Contents of heavy metals in soil samples from upstream of river on north side of tailings pond are about the same as those from its downstream. Stockpiling of tailings only has a very slight effect on accumulation of heavy metals in soil around river on north side. Contents of Cd element in rice samples in mining area are below the standard, and mining mineral processing has no significant impact on food safety of rice around mining area.
