| 摘 要： | 采用生态危害指数法等对福建浅海沉积物样品中7种重金属（Hg、Pb、Cr、Zn、Cu、Cd、As）测试结果进行分析与评价，结果表明与海洋积物一类标准对比，福建各主要海湾浅海沉积物重金属超标以Cr、Cu为主，以Pb、zn为次，地质累积指数超标的Cr、Cu、Pb、Zn潜在生态风险不大；九龙江口以Cd潜在生态风险最高，潜在生态危害最大。研究表明，采用地质累积指数评价和生态风险评价法二者结合应用能较为合理地对重金属污染状况进行系统评价。

| Abstract: | By the index method of ecological hazard, the author made an assay and evaluation of actual survey results of seven heavy metals( Hg, Pb, Cr, Zn, Cu, Cd, As) from the samples of near-shore sediment in Fujian Province. It is shown that the Class-I standard of marine sediment, the heavy metals of major gulf and near-shore sediment in Fujian Province go beyond the Class-I standard of marine sediment, the heavy metals Cr and Cu are in the first place, accounting respectively for 24.1and 15 per cent, and the heavy metals Pb and Zn are in the next place, respectively taking up 6.3 and 5 per cent. The heavy metals Cr, Cu, Pb and Zn, which overtop the standard because of the cumulation in geological history, are not too potential ecology hazards. In the Jiulong River estuary, the heavy metal Cd has a high potential ecological risk and a maximal potential ecological hazard. The research results are shown that both the evaluation of geologic cumulation indices and the method of the ecology risk evaluation can be used to more reasonably evaluating the heavy metal pollution. |
