We analyzed eight heavy metals (Cu, Pb, Zn, Cr, Cd, Hg, As, and Ni) in 85 seabed sediments off the coast of Weihai City, eastern Shandong Peninsula, China, to reveal their distributions, enrichment status, and pollutant sources. Cu, Pb, Zn, Cr, As, and Ni were enriched in all bays in both the inner and outer waters. However, Cd and Hg were more abundant in Weihai Bay, followed by Rongcheng Bay and Chaoyang Port, with denser populations and more developed industries near the coast. Most areas exhibited slight contamination with As and Pb, with relatively severe contamination in localized areas. Moreover, Weihai Bay showed slight contamination with Cd, Zn, and Hg. Heavy metals are largely influenced by the discharge of anthropogenic pollutants along the coast. It is recommended to implement strict control measures on the discharge of waste into the sea, and ensure the sustainable development of the marine ecological environment.
我们分析了中国山东半岛东部威海市海岸附近85个海床沉积物中的8种重金属（铜、铅、锌、铬、镉、汞、砷和镍），以揭示它们的分布、富集状况和污染物来源。铜、铅、锌、铬、砷和镍在内外水域的所有海湾中均有富集。然而，镉和汞在威海湾更为丰富，其次是荣成湾和朝阳港，这些地方海岸附近人口密集且产业更发达。大多数地区砷和铅呈现轻微污染，局部地区污染相对严重。此外，威海湾镉、锌和汞呈现轻微污染。重金属在很大程度上受到沿海人为污染物排放的影响。建议对向海洋排放废物实施严格控制措施，确保海洋生态环境的可持续发展。
