摘要
在阐述铅、锶、钕同位素作为示踪剂原理的基础上,总结了铅同位素示踪技术和铅、锶、钕同位素联合示踪技术在PM_(2.5)源解析中的应用,并指出今后研究PM_(2.5)源解析的重点:应用铅、锶、钕同位素联合示踪技术,在明确区分PM_(2.5)中各污染来源的同时定量计算各源的贡献值,并结合后向气团轨迹分析模型解析PM_(2.5)的远距离来源。
PM2.5 has increasingly caused public concern due to its serious impact on air quality and human health. The recognition of pollution sources to PM2.5 is essential for making relevant policies, which could solve PM2.5 pollu-tion problems fundamentally. Based on the principles of Pb, Sr and Nd isotopes as tracers, the applications of Pb iso-topic tracing combiningPb, Sr, Nd isotopic technique on recognizing and analyzing pollution sources of PM2.5 were summarized in this paper. The combined isotopic tracing techniques of Pb, Sr and Nd were applied to distinguish and quantify the contributions of various pollution sources to PM2.5. Combining the air - mass backward trajectory model-ing with isotopic tracing technique, the long - range transported sources to PM2.5 was recognized and analyzed.
