挥发性有机硫化合物释放及对全球环境的影响

摘要

介绍了几种挥发性有机硫化合物：甲硫醚(DMS)、羰基硫(COS)、甲硫醇(MSH或CH3SH)、二硫化碳(CS2)和二甲基二硫(DMDS)从各种自然源(主要是生物源)释放的情况，并论述了有机硫气体释放对全球环境和气候的影响。着重阐述了在海洋、陆地生态系统中，各种生物硫源的释放情况和有机硫气体的迁移、转化规律。讨论了大气中痕量有机硫气体的分析方法，并提出一些建议。%Emission situations of several volatile organic sulfur compounds, such as: DMS, COS, CH3SH, CS2 and DMDS from natural sources (especially biological source) have been introduced, and effects of the emission on global climate and environment were summarized, and discussion on emission situations of various biological surfur sources and laws of transference and transformation of organie sulfur compounds in ocean and terrestrial ecosystem werernfocused, The analytical methods of these trace gases in atmosphere were also discussed, and a few proposes of further work were put forward.
