In this study, we analyzed heavy metals in 404 surface sediment samples from the Bohai Sea to measure contamination status and distribution. We found Zn levels to be the highest, whereas Hg concentrations were the lowest of measured heavy metals. We found that the samples containing the most heavy metals were those collected from Fuzhou Bay, Jinzhou Bay, central Bohai Sea mud area, and the Yellow River Delta. Further analyses suggest that these heavy metals in surface sediments in the Jinzhou Bay and Fuzhou Bay pose a serious ecological risk, with substantial Cd and Hg accumulation in the Jinzhou Bay and Yellow River Delta regions being indicative of intense human activities.
本研究分析了渤海 404 个表层沉积物样品中的重金属，以测量污染状况和分布。结果表明，在所测重金属中，Zn 的含量最高，而 Hg 的浓度最低。我们发现重金属含量最高的样品来自福州湾、锦州湾、渤海中部泥区和黄河三角洲。进一步分析表明，锦州湾和福州湾表层沉积物中的这些重金属存在严重的生态风险，锦州湾和黄河三角洲地区的 Cd 和 Hg 大量积累表明人类活动强烈。
