DENG Yan, YU Ze-bin, ZHOU Yan-wu, CHEN Lan, PENG Xiao-yan, LAN Wen-lu. Pollution status and potential ecological risk assessment of heavy metals in surface sediments of Anpu port[J]. Chinese Journal of MARINE ENVIRONMENTAL SCIENCE, 2017, 36(3): 398-405. DOI: 10.13634/j.cnki.mes20170313

Seven heavy metals (Cu, Pb, Zn, Cd, Hg, Cr, Hg, As) were investigated for their content distribution and ecological harm in Anpu port where 21 samples were collected in its deposit.The pollution level of these heavy metals was evaluated using single factor pollution coefficient and comprehensive pollution index.Meanwhile, the potential hazards of heavy metals were predicted using the Hàkanson potential harm coefficient and potential ecological risk index.The results showed that spatial divergence of these heavy metals was fairly large and pollution level was in low environmental pollution in general, by the order of Hg > Cd > Pb > As > Zn > Cu > Cr.The potential ecological risk was in a low ecological hazard category overall, and the sequence of harm coefficient was Hg > Cd > As > Pb > Cu > Cr > Zn.There was significant positive correlation between each heavy metals except Cd.
