Short summary
This study reveals that anthropogenic organosulfates (OSs), especially Aliphatic OSs in urban areas have been significantly underestimated. We also discovered that humidity, acidity, inorganic sulfate and Ox mass concentrations play key roles in the formation of Aliphatic OSs. These findings improve our understanding of how air pollution forms in urban environments and are crucial for developing effective environmental policies.
