摘　　要：2021年10月在舟山鱼山岛周边海域布设16个沉积物站位点,并在不同站点对该海域沉积物取样并进行重金属含量分析来阐明该海域的污染状况和生态危害水平。结果表明:鱼山岛周边海域所有站位沉积物中所检测的重金属含量均在第一类海洋沉积物质量标准规定的范围内。其中,铜平均污染程度最高,镉、铅、铜、锌处于中度污染水平,是主要的污染因子。重金属镉的潜在生态危害系数相对较高,是主要的潜在生态风险因子。各站位潜在生态危害系数均小于150,表明鱼山岛周边海域总体处于低生态危害水平。In October 2021,16 sediment stations were set up in the sea area around Yushan Island,Zhoushan,to investigate and analyze the heavy metals in the sediments of the sea area,and further evaluate the pollution status and ecological hazard level of heavy metals.The results showed that the contents of heavy metals detected in sediments from all stations meet the quality standard of the first class marine sediments,The pollution degree of copper is the highest,among which cadmium,lead,copper and zinc are at the moderate pollution level and are the main pollution factors.The potential ecological hazard coefficient of cadmium is relatively high.The potential ecological hazard coefficient of all stations is less than 150,indicating that the sea area around Yushan Island are at a low ecological hazard level.
