溴甲烷是大气中重要的痕量温室气体,对全球变暖和大气化学具有重要作用.海洋在溴甲烷的生物地球化学循环中作用复杂,海洋既是大气溴甲烷的源也是其汇,开展海洋环境中溶存溴甲烷的化学研究,对大气臭氧层的保护工作具有一定的指导意义,也可为在全球尺度上估算海洋环境中溴甲烷对全球环境变化的贡献提供理论依据.本文从溴甲烷的生物地球化学循环、分析测定方法、浓度分布、海-气通量、源汇平衡等方面综述了国内外海洋环境中溴甲烷的研究进展,探讨了目前该领域研究中存在的不足,并对未来的研究进行了展望.
Methyl bromide is an important trace-level greenhouse gas in the atmosphere and plays an important role in global warming and atmospheric chemistry. The ocean plays a complex role in the biogeochemical cycle of methyl bromide. The ocean is not only the source of atmospheric methyl bromide, but also the source of dissolved methyl bromide in the marine environment Chemical research is of guiding significance for the protection of atmospheric ozone layer and also provides a theoretical basis for estimating the contribution of methyl bromide to the global environmental change on a global scale.On the basis of biogeochemical cycles of methyl bromide, analytical methods, Concentration distribution, sea-air flux and source-sink balance, the research progress of methyl bromide in marine environment at home and abroad are reviewed. The existing problems in this field are discussed and the future research is prospected.
