Short summary
Organosulfates are ubiquitous in the atmosphere. We find that chemical transformation of IEPOX-derived organosulfates, one of the most abundant organosulfates, can generate inorganic sulfate through heterogeneous OH oxidation. The findings of this work provide new reaction pathways for recycling of inorganic and organic sulfur and may suggest that organosulfates could be reservoirs of inorganic sulfates in the atmosphere.
