Organosulfates in the Atmosphere

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 of Environmental Chemistry 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.

The papers will go through the usual review process, and will be published Online Early as they are accepted. However, as they will be compiled across several issues of Environmental Chemistry, they are being collated into this virtual issue as they are published. Deadline for submissions is 1 September 2019.

Environmental context. Organosulfates in the atmosphere are an indicator that particulate matter has formed from gases in the presence of anthropogenic pollution. By characterising organosulfates in atmospheric fine particulate matter from the Midwestern USA, we found that organosulfates account for a significant fraction of organic carbon and that they are associated with both plant-derived and anthropogenic gases. Our results demonstrate that anthropogenic pollution significantly influences atmospheric particle concentrations and composition.


Environmental context. Secondary organic aerosols account for a major fraction of atmospheric particulate matter, affecting both climate and human health. Organosulfates, abundant compounds in organic aerosols, are difficult to measure because of the lack of authentic standards. Here we quantify terpene-derived organosulfates in atmospheric particulate matter at a rural site in Germany and at the North China Plain using a combined target/non-target high-resolution mass spectrometry approach.
