Aerosol chemistry and photochemistry in polluted urban environments: research for tomorrow’s megacities

点击翻译按钮获取中文摘要

Although our current understanding of urban air quality comes largely from studies conducted in North America and Western Europe, the bulk of today’s urban growth is occurring in developing Asian and African megacities. The overarching goal of our group's research is to explore light-induced chemistry (photochemistry) that may be promoted in the metal- and soot-rich atmospheric particulate matter (aerosol) typical of developing urban regions and industrially influenced areas, and thus improve our understanding of the processes that govern air quality in these understudied environments.
