Understanding the sources of atmospheric chlorine in a mid-continental megacity

EPSRC：乔丹·斯图尔特：EP/R513386/1大气氧化剂负责降解和最终清除绝大多数排放到大气中的物质。因此，如果我们要制定有效和及时的政策，解决空气质量和气候变化等紧迫的社会问题，就必须全面了解这种化学作用。氯原子是这些氧化剂中了解最少的，目前还没有被纳入常规预测空气质量和气候的模型中。然而，过去十年的研究表明，氯可能比以前认为的更重要。一个尚未回答的主要问题是中部大陆地区氯的来源，模型预测那里的氯很少。该项目通过为现有的国际测量计划做出贡献，着眼于全球特大城市的空气质量，将测量中部大陆特大城市（多伦多）的关键氯化合物。这将提供关于这一重要环境中氯来源的重要数据。

EPSRC : Jordan Stewart : EP/R513386/1Atmospheric oxidants are responsible for the degradation and ultimate removal of the vast majority of emissions into our atmosphere. A complete understanding of this chemistry is therefore essential if we are to develop effective and timely policies that address the pressing societal problems of air quality and climate change. Chlorine atoms are the least understood of these oxidants, and are currently not included in models that routinely forecast air quality and climate. However, work over the last decade suggests chlorine could be more important than previously thought. A major unanswered question is the source of chlorine in mid-continental regions, where models predict there to be very little. By contributing to an existing international measurement program looking at air quality in global megacities, this project will make measurements of key chlorine compounds in a mid-continental megacity (Toronto). This will provide vital data on the sources of chlorine in this important environment.
