摘要:
文章根据2017 年8 月北仑河口红树林自然保护区近岸海域表层沉积物监测结果，分别采用单因子污染指数法和Hakanson 沉积物重金属潜在生态风险指数法分析该保护区沉积物重金属的污染状况和潜在生态风险程度。结果表明：该保护区沉积物重金属含量由高到低依次为Zn、Cr、Cu、As、Pb、Hg、Cd，其平均含量均低于国家海洋沉积物质量第一类标准。沉积物重金属污染指数大小排序为Hg、As、Cu、Cr、Zn、Pb、Cd，其中Hg 的污染指数较高，表明保护区有受到Hg 的沾污；重金属潜在生态风险程度为低，由高到低依次为Hg、As、Cd、Cu、Cr、Pb、Zn。
Abstract:
Based on the monitoring results of surface sediments in the coastal waters of the Beilun Estuary Mangrove Nature Reserve in August 2017. The single-factor pollution index method was used to analyze the pollution status of heavy metals in surface sediments of the natural reserve zone, and the potential ecological risk index method of heavy metals was used to analyze the degree of potential ecological risk. The results show that the content of heavy metals in surface sediments of the natural reserve zone from high to low was Zn, Cr, Cu, As, Pb, Hg and Cd. And the average content was lower than the first-class standard of national marine sediment quality. The heavy metals pollution index of sediments was ranked as Hg, As, Cu, Cr, Zn, Pb, Cd. Among them, the pollution index of Hg was higher, indicating that the natural reserve zone was contaminated by Hg. The potential ecological risk of heavy metals from high to low was Hg, As, Cd, Cu, Cr, Pb, Zn, they all were low.
