Anthropogenic metal pollution is a leading environmental problem in southern China, especially in remote regions where its impact remains poorly understood. This study investigates the historical variation of heavy metal pollution over the last 200 years using a sediment core from Xincun Lagoon, Hainan Island, South China. The temporal evolution of heavy metal pollution aligns with China's socioeconomic development. Prior to the 1950s, heavy metal concentrations were at geochemical background levels, reflecting China's agrarian status. Since the 1950s, the increased heavy metal accumulation may be attributed to intensified human activities linked to rapid urbanization and industrialization. Despite the increase in heavy metal enrichments since the 1950s, Xincun Lagoon currently faces a low ecological risk.
人为金属污染是中国南方，尤其是偏远地区的一个主要环境问题，但其影响仍未得到充分了解。本研究利用取自海南岛新村泻湖的沉积岩芯，调查了过去 200 年来重金属污染的历史变化。重金属污染的时间演变与中国的社会经济发展相一致。在 1950 年代之前，重金属浓度处于地球化学背景水平，反映了中国的农业地位。自 1950 年代以来，重金属积累的增加可能归因于与快速城市化和工业化相关的人类活动的加剧。尽管自 1950 年代以来重金属含量有所增加，但新村泻湖目前面临的生态风险较低。
