Sulfur plays a major role in air pollution due to the copious emissions of sulfur dioxide from fossil fuel combustion. In the atmosphere, sulfur dioxide is oxidized to sulfuric acid, which drives multiphase chemistry with organic compounds of biogenic origin to create a plethora of organosulfate compounds in the aerosol phase. Evaluation of the environmental and health impacts of organosulfates relies on knowledge of their molecular composition as well as quantitative information about their atmospheric presence. This Research Front brings together papers reporting the detection and quantification of organosulfates in various atmospheric environments across the world, and thereby produces new insights into the atmospheric chemistry of organosulfates.
