| 摘 要： | 本文通过对自20世纪80年代以来九龙江口-厦门湾海域的表层沉积物重金属调查数据进行对比分析,确定了各区域重金属含量的平均水平,对表层沉积物重金属含量分布作了概述,同时根据潜在生态风险指数法的需要确定了各重金属元素含量的背景值,为该区域重金属含量的研究和评价以及背景值提供了参考数据。结合2016年8月该区域表层沉积物重金属含量调查数据,进行了总体潜在生态风险评价,结果表明:九龙江口-厦门湾海域的表层沉积物重金属潜在生态风险情况并不乐观,厦门东部水道部分海域重金属潜在生态风险以轻度风险为主,九龙江口海域重金属潜在生态风险以重度风险为主,其余海域以中度风险为主。

| Abstract: | According to the comparative analysis result of historical heavy metals contents in the surface sediments from the Jiulong River Estuary and Xiamen Bay from 1980s, the average value of heavy metals contents in this sea area was established, and the overview of heavy metals distribution characteristic has been made. Besides, the background level of heavy metal element contents was determined according to the need of potential ecological risk index method, it provides the reference data of average value and background level for further research and evaluation. Combined with the survey data in August, 2016, the integrated risk evaluation results indicated an unoptimistic situation of this sea area, the eastern of Xiamen Sea Area mainly belonged to low ecological risk, Jiulong River Estuary mainly belonged to heavy ecological risk, and the rest of Xiamen Bay mainly belonged to moderate ecological risk. |
