摘　　要：锌是生命活动必需的微量元素之一,但在过量的情况下,会造成环境污染、生态毒害和人体健康危害,因此锌的环境地球化学行为研究是科学合理利用锌的基础,也是相关领域的研究热点。锌有五个稳定同位素,不同来源的锌同位素组成不同。通过测定不同环境样品中的锌同位素组成,为研究锌的环境地球化学提供了新的手段。近年来随着多接收电感耦合等离子体质谱仪(MC-ICP-MS)测试技术的发展,锌同位素环境地球化学研究已经覆盖了化学风化、污染溯源、古气候重建和生物过程等,并且新的研究领域不断拓展。文章对锌同位素分析方法及其在环境地球化学方面的研究现状进行详细综述,并对锌同位素环境地球化学的未来发展进行展望,以期推动该领域的进一步发展。Zinc is one of the essential trace elements for life activities,but in excess,it can cause environmental pollution,ecological toxicity,and harm to human health.Therefore,the study of the environmental geochemical behavior of zinc is the basis for the scientific and rational use of zinc,and it is also a research hotspot in related fields.Zinc has five stable isotopes,and the isotopic composition of zinc varies from different sources.The determination of zinc isotope composition in different environmental samples provides a new means for studying the environmental geochemistry of zinc.In recent years,with the development of multicollector inductively coupled plasma mass spectrometry(MC-ICP-MS),the study of zinc isotope environmental geochemistry has covered chemical weathering,pollution tracing,paleoclimate reconstruction,and biological processes,and new research fields are constantly expanding.The article provides a detailed overview of zinc isotope analysis methods and their current research status in environmental geochemistry,and looks forward to the future development of zinc isotope environmental geochemistry,in order to promote further development in this field.
