  • Qinzhou Gulf was selected as the research area because of frequently human activities. Seven heavy metals in surface sediments were studied by various methods. The results showed that the contents of As and Hg were higher than those in other similar areas, the contents of Pb and Cr were equal, and the contents of Cr, Cu and Zn were lower. In recent years, the content heavy metal contents increased, and the high value points were all close to some industrial sewage emission and human activity areas. The evaluation results of random accumulation model showed that Cd was in no pollution to medium pollution level, and 34% of them had probability to deteriorate to medium pollution level; other heavy metals were in no pollution level, and 48% of As and 24% of Hg had the probability of deterioration. The order of potential ecological risk was Cd>Hg>As»Pb>Cu>Zn≈Cr; speciation analysis showed that Hg mainly existed in the form of stable residue, suggesting that the migration between sediment and seawater was weak and the availability of Hg was low; the results of principal component analysis showed that Cd mainly came from port shipping and dredging activities, and other heavy metals mainly came from industry (sugar, coal, petrochemical, etc.) and land-based municipal sewage. The heavy metal content in Qinzhou Bay was mainly affected by industry and human activities.
