中文摘要：

铊（TI）是一个典型性的毒害重金属元素,在环境中的迁移转化行为、富集机制、毒性和生物效应与其赋存化学形态密切相关.本文对水体、土壤和沉积物中Tl化学形态分布、演化特征和化学形态分析方法作了系统总结和评述,并对Tl化学形态分析存在问题及未来发展趋势进行了展望.

英文摘要：

Thallium is a typical toxic element.The transport,transformation behavior,enrichment mechanism,toxicity and biological effect of Tl is closely related to its occurrence chemical form in the environment.The chemical speciation and speciation analysis methods of thallium in water,soil and sediment were summarized and reviewed.The existing problems of the speciation analysis of thallium and the development of the speciation analysis of thallium in the future were also prospected.
