Halogen chemistry is well known for ozone destruction in the stratosphere, however reactive halogens also play an important role in the chemistry of the troposphere. In the last two decades, an increasing number of reactive halogen species have been detected in a wide range of environmental conditions from the polar to the tropical troposphere. Growing observational evidence suggests a regional to global relevance of reactive halogens for the oxidising capacity of the troposphere. This critical review summarises our current understanding and uncertainties of the main halogen photochemistry processes, including the current knowledge of the atmospheric impact of halogen chemistry as well as open questions and future research needs.
卤代烃化学在平流层臭氧破坏方面是众所周知的，但活性卤素在对流层化学中也起着重要作用。在过去的二十年中，在从极地到热带对流层的各种环境条件下，已经检测到越来越多的活性卤素物质。越来越多的观测证据表明，活性卤素对对流层的氧化能力具有区域乃至全球意义。这篇评论总结了我们目前对主要卤代烃光化学过程的理解和不确定性，包括卤代烃化学对大气影响的现有知识以及未解决的问题和未来的研究需求。
