Short summary

Particulate amines play an important role for the particle acidity and hygroscopicity. We found amines were internally mixed with sulfate and nitrate at a rural site in the PRD, China, suggesting the formation of aminium sulfate and nitrate salts. The ammonium-poor state of amine particles in summer was associated with the low emission sources of ammonia and a possible contribution of ammonium–amine exchange reactions. Amines could be a buffer for the particle acidity of ammonium-poor particles.
