[Distribution characteristics and risk assessment of heavy metals in farming domestic muscovy duck originated from Au/Cu mining and smelting activites].

To investigate the impacts of mining and spilling activities on domestic fowl raising, ten muscovy duck (Cairna moschata) samples were collected in 2010 from farms in different villages located at the banks of the river originated from an Au/Cu mine. Concentrations of Cu, Hg and As in muscle, liver and blood of the muscovy duck samples were determined. According to relative national standards of China, the health safety of heavy metals in muscovy duck was evaluated.

[Heavy metals distribution characteristics and risk assessment of water below an electroplating factory].

Surface water and shallow groundwater within the flow of an electroplating factory was analyzed in order to study the resulting impact. The analysis method of ICP-AES was used to analyze content of zinc, manganese, chromium, copper and nickel in surface water and groundwater samples. The results indicate acidic pollutants of zinc, manganese, chromium, copper and nickel were discharged from the factory with concentrations of 1.
