Abstract: 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.

Key words: Zinc isotopes, analytical methods, fractionation mechanisms, environmental geochemistry
