铅稳定同位素示踪技术的研究进展

Research progress on lead stable isotope tracer technique

铅稳定同位素示踪技术是通过测定各种介质中4种铅稳定同位素(204Pb、206Pb、207Pb和208Pb)的比值,来追踪含铅物质来源的技术。目前已经应用于考古、地质勘探、环境污染、食品安全以及医学等专业研究领域,是进行铅污染暴露来源解析的重要手段。本文就其在相关领域的研究应用进展进行阐述。

Lead isotope tracer is such a technique that through the determination of four lead isotope （204 Pb,206Pb,207 Pb and 208Pb） ratio in various medias to track the source of lead compounds. At present, this technique is already widely used in the studies of archaeology, geological exploration, environmental pollution, food safety and medicine. It is a important way of analyzing the sources of lead pollution exposure. This paper will make a brief summarization on the application of the technique on related fields.
