According to the code of marine monitoring, As was analyzed by atomic fluorescence, Hg was analyzed by atomic absorption spectrophotometry, and Pb, Cd and Cu were analyzed by anodic stripping voltammetry. The changes of heavy metals concentration and potential ecological risk indices in different depths of 3 cores from the south oft-com:office:smarttags" />Haizhou Bay were analyzed by those methods, and the contamination history of heavy metals was also discussed combined with the ^2l0 Pb dating. The results show that the concentration of heavy metals varied with depth like zigzag; the correlation with organic matter indicated that As, Cu and Pb were related to human contamination; the pollution of heavy metal is low on the whole, and Hg is the primary element of pollution, which is seriously harmful to ecology.oft-com:office:office" />
