摘　　要：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 atmospheric trace gas, which plays significant roles in the global warming and atmospheric chemistry. The ocean plays important and complex roles in the global biogeochemical cycles of methyl bromide, not only the source of atmospheric methyl bro- mide, but also the sink. Therefore, developing the chemical research of the soluble methyl bromide in the ocean, will not only have a certain guiding significance to the atmospheric ozone layer protec- tion, but also provide a theoretical basis for estimating methyl bromide＇s contribution to the global environmental change on global scale. This paper reviewed the research advances on methyl bro- mide in the ocean, from the aspects of the biogeochemical cycle of methyl bromide in the ocean, the analysis and determination method, the concentration distribution, the sea-to-air flux and its sources and sinks in the atmosphere. Some deficiencies in the current studies were put forward, and the di- rections of the future studies were prospected.
