- Abstract:
- The paper chooses the artificial lake-ponds as the research object in the Chengdu economic zone, analyzes the distribution of heavy metal in the sediments, and evaluates with the index of Geoaccumulation. The results indicated the index of heavy metals in the sediment decreases followed Hg>Cd>Pb>Cu>Zn>As. Hg is the main pollutant belonging to the strong-greatly strengthened pollution, Cd, Pb, Cu belongs to the strong pollution. Donghu lake which approaches the industrial district is the most seriously pollution, next one is Qinglong Fishery near the suburb, the pollution of the out suburb Chaoyang reservoir is lighter.
