摘　　要：汞是一种全球性污染物。大气颗粒态汞在青藏高原的大气汞沉降中扮演着重要的角色,长距离传输和沉降使得偏远地区也受到人为排放汞的影响。文章介绍了大气颗粒态汞在青藏高原汞生物地球化学循环中的重要性和当前的研究进展,并展望了未来的研究方向。第二次青藏高原综合考察研究项目,将对大气颗粒态汞进行更深入和系统的研究。基于汞同位素和模式模拟等方法,进一步量化大气颗粒态汞跨境传输及其对环境的潜在影响,为青藏高原的环境保护提供科学支撑。Mercury(Hg)is a global pollutant because the atmospheric Hg can be transported globally and deposited into aquatic and terrestrial environments even in remote regions.Atmospheric particulate-bound mercury(PBM)plays a critical role in Hg deposition on the Tibetan Plateau.The importance of atmospheric PBM in Hg biogeochemical cycling on the Tibetan Plateau and research process was introduced in this article.Supported by the second Tibetan Plateau scientific expedition and research program,transboundary transport of atmospheric PBM and its potential environmental effect will be profoundly studied.These results are expected to provide valuable and fundamental scientific basis for the regional environmental protection.
