Coastal areas of South China face great challenges due to heavy metal contamination caused by rapid urbanization and industrialization. In this paper, more than 90 articles on levels, distributions, and sources of heavy metals in sediments and organisms were collected to review the status of heavy metal pollution along coastal regions of South China. The results show that heavy metal levels were closely associated with local economic development. Hong Kong and the Pearl River Estuary were severely contaminated by heavy metals. However, concentrations of heavy metals in sediments from Hong Kong have continually decreased since the early 1990 s. High levels of heavy metals were found in biota from Lingdingyang in Guangdong province. Mollusks had higher concentrations of heavy metals than other species. Human health risk assessments suggested that levels of heavy metals in some seafood from coastal areas of South China exceeded the safety limit.
中国南方沿海地区由于城市化和工业化的快速发展导致重金属污染，面临着巨大的挑战。本文收集了 90 多篇关于沉积物和生物体内重金属含量、分布和来源的文章，综述了中国南方沿海地区重金属污染的现状。结果表明，重金属含量与当地经济发展密切相关。香港和珠江口受到了严重的重金属污染。然而，自 20 世纪 90 年代初以来，香港沉积物中的重金属浓度持续下降。广东伶仃洋的生物体内重金属含量较高。贝类的重金属含量高于其他物种。人体健康风险评估表明，中国南方沿海地区部分海产品中的重金属含量超过了安全限值。
