Heavy Metal Element Sedimentary Record Adjacent to the Pingtan Island

Abstract:

Upwelling is common phenomenon in the continental shelf sea area. Upwelling can bring the deep nutrient-rich water to the surface ocean,at the same time, upwelling areas tend to have higher deposition rate and easier to form the muddy area.Studies have shown that fine suspended particular plays an important role in the control of the distribution of heavy metals in the sediments. The results in the Pingtan Island upwelling area show that Cr element content is relatively exceeding seriously,Zn content exceeded in certain regions, other elements has slightly overweight in some stations compare to the Sediment environmental quality standards and the average value in the offshore of Fujian coast, with a magnifying glass effect.However,this area is a famous fishing ground, which means the enrichment of heavy metal may be through to aquatic organisms of animals and plants enrichment, likely through the food chain will ultimately affect the human life.
