Heavy Metal Distribution and Sedimentary Control in the East Side of Pingtan Island

Abstract

Analysis the heavy metal element content and grain size of surface sediment in the eastern of Pingtan Island around the upwelling region, combined with the correlation analysis methods, discusses the relationship between the sediment grain size and content of heavy metal elements in this upwelling region. The results show that, fine particulate matter has certain enrichment effect to some heavy metal elements. Correlation analysis showed that, fine particulate matter can enriched heavy metal elements, such as Pb, Zn, Cu, Ni, Co. and the Cr and As elements showed certain independence, and not relevant with the particle size, no obvious correlation with the other heavy metal elements, only has certain correlation with individual elements, show that this element have certain degree of selectivity.
