| 摘 要： | 为了解柘林湾及邻近海域沉积物中重金属含量分布及其对海湾生态危害状况，于2011年4月采集了柘林湾及邻近海域18个站位表层沉积物样品，分析了沉积物中的重金属质量分数。结果表明，柘林湾及邻近海域重金属质量分数均低于海洋沉积物I类标准，研究海域沉积物中铅（Pb）、铬（cr）、铜（cu）和锌（zn）的质量分数分别为7．71．31．20mg·kg-1、12．71～63．56mg·kg-1、2．36-120．38mg·kg-1和12．50～85．58mg·kg-1潜在生态风险评价表明，柘林湾及邻近海域重金属危害属于轻微污染，重金属生态危害程度顺序为Cr〉Pb〉Cu〉Zn。

| Abstract: | We collected 18 surface sediment samples from Zhelin Bay and its vicinity in April 2011 and determined the concentration of selected heavy metals to study their potential ecological risks. The results reveal that the concentrations of lead （ Pb）, chromium （Cr） , copper （Cu） and zinc （Zn） all meet the quality standard of class I of China National Standard Criteria for Marine Sediment Quality, which are 7.71 ~ 31.20 mg.kg-~ （Pb）, 12. 71 -63.56 mg＇kg-1 （ Cr）, 2. 36 - 20. 38 mg＇kg-1 （Cu） and 12. 50 - 85.58 mg＇kg-1 （Zn）, respectively. The potential ecological risk index and factors indicate that the potential ecological risks of these heavy metals are of low level. The sequence of the degree of their potential ecological factors is Cr 〉 Pb 〉 Cu 〉 Zn. |
