Short summary
The solubilities of iron in fine particles in a megacity in Eastern China were studied under haze, fog, dust, clear, and rain weather conditions. For the first time, a receptor model was used to quantify the sources of dissolved and total iron aerosol. Microscopic analysis further confirmed the aging of iron aerosol during haze and fog conditions that facilitated dissolution of insoluble iron.
