This paper reports the contents of six heavy metals and particle sizes in the surface sediments of 120 sampling stations in the southern North Yellow Sea to reveal heavy metal distribution characteristics, contamination assessment, and sources. Cu and Cr enrichments were mainly found in coastal areas with high mud content (silt and clay). However, Zn, Cd, Pb, and Hg were enriched in Weihai Bay and Dongpu Bay, which have denser populations, estuaries, and shipyards. The geoaccumulation index and principal component analysis showed that Cu and Cr contamination was low, and the sources were mainly natural processes. In addition, Zn and Cd pollution in the nearshore area was moderate, and its provenance was natural processes and human activity. However, most areas exhibited Pb and Hg contamination due to waterborne traffic and industries, including shipbuilding and gold mining.
本研究报告了北黄海南部 120 个采样站表层沉积物中 6 种重金属和粒径的含量，旨在揭示重金属的分布特征、污染评估和来源。Cu 和 Cr 主要富集在高泥含量（粉砂和粘土）的沿海地区。然而，Zn、Cd、Pb 和 Hg 则在人口密集、有河口和造船厂的威海湾和东浦湾富集。地积累指数和主成分分析表明，Cu 和 Cr 的污染程度较低，来源主要是自然过程。此外，近岸地区 Zn 和 Cd 的污染程度为中等，其来源是自然过程和人类活动。然而，由于水运交通和包括造船和采金在内的工业，大多数地区的 Pb 和 Hg 受到污染。
