摘　　要：人类社会的发展进程导致土壤和沉积物中的重金属含量远远超过背景值,具有严重的潜在威胁隐患。然而,由于重金属的流动性、毒性以及生物累积性会对环境造成深远影响,重金属形态分析已然成为环境研究的重要一环。目前最具代表性的形态提取方法为Tessier法和BCR三步法,为标准物质研制、重金属污染评估、生态修复以及生物有效性风险等问题提供了有效解决方案,但也有着各自的局限性。总结目前常用的元素形态提取分析方法,系统对比论证,讨论重金属形态分析方法未来可能出现的问题和发展方向,以期为土壤及沉积物重金属污染研究提供思路与支撑。The development of human society has resulted heavy metal content in soil and sediment far exceeds background values,posing serious potential threats and hidden dangers.However,with the profound impact of heavy metal mobility,toxicity,and bioaccumulation on the environment,it is a significant segment that speciation analysis to environmental research.At present,the most representative approaches are the Tessier method and the BCR three-step method.This provides effective solutions for issues such as reference material development,heavy metal pollution assessment,ecological restoration,and bioavailability risk judgement,but still possesses respective limitations.In order to provide ideas and support for research on soil and sediment heavy metal pollution,the commonly used elemental morphology extraction and analysis methods were summarized and the potential problems and development directions of heavy metal speciation analysis methods in the future were systematically compared and discussed in this article.
