于2011—2012年,对象山港12个站位表层沉积物进行周年季节性采样,测定了Ni、Cu、Zn、As、Pb和Ba 6种重金属含量,并对其生态风险进行了评估。结果显示,象山港Ni、Cu、Zn、As、Pb和Ba的年平均含量分别为44.45、37.49、134.42、28.96、31.96、556.96 mg/kg,其中, Ni、Cu、Zn和As最高含量发生在西沪港,而Pb和Ba的最高含量发生在黄墩港。与国家海洋沉积物质量I类标准相比, As和Zn超标率分别为44.8%和7.1%。据潜在生态风险指数评价结果,各海域污染程度顺序为西沪港>港口区>狭湾>黄墩港>铁港区,各重金属的污染程度顺序为:As>Ni>Pb>Cu>Ba>Zn;按照生物毒性评价结果,6种重金属基本不会产生生物毒性。
于2011—2012年,對象山港12箇站位錶層沉積物進行週年季節性採樣,測定瞭Ni、Cu、Zn、As、Pb和Ba 6種重金屬含量,併對其生態風險進行瞭評估。結果顯示,象山港Ni、Cu、Zn、As、Pb和Ba的年平均含量分彆為44.45、37.49、134.42、28.96、31.96、556.96 mg/kg,其中, Ni、Cu、Zn和As最高含量髮生在西滬港,而Pb和Ba的最高含量髮生在黃墩港。與國傢海洋沉積物質量I類標準相比, As和Zn超標率分彆為44.8%和7.1%。據潛在生態風險指數評價結果,各海域汙染程度順序為西滬港>港口區>狹灣>黃墩港>鐵港區,各重金屬的汙染程度順序為:As>Ni>Pb>Cu>Ba>Zn;按照生物毒性評價結果,6種重金屬基本不會產生生物毒性。

In 2011-2012, seasonal surface sediments were sampled from 12 stations of Xiangshan Bay, the concentrations of 6 heavy metals including Ni, Cu, Zn, As, Pb, and Ba were analyzed and the potential ecological risks of heavy metals were evaluated. The re-sult showed that average contents of Ni, Cu, Zn, As, Pb and Ba were 44. 45, 37. 49, 134. 42, 28. 96, 31. 96 and 556. 96 mg/kg, respec-tively. Compared with the China marine sediment quality I, the over standard rates of As and Zn were 44. 8%and 7. 1%, respectively. Potential ecological risk factors indicated that the order of the pollution degree in each zone is Xihu Gang>Port area>Fjord>Huang-dun Gang>Tie Gang, the risk index of 6 heavy metals were in order of As>Ni>Pb>Cu>Ba>Zn. The result of toxicity evaluation showed that 6 heavy metals will not bring toxic effect.
