Short summary
Nitrogen-containing organic aerosols can affect health, environment, and climate; however, their formation mechanism is still poorly understood. Based on Orbitrap-MS (mass spectrometer), our study reveals a previously unrecognized atmospheric reaction pathway in which ammonia can efficiently scavenge stable Criegee intermediates. This new reaction produces nitrogen-containing organic compounds with a reactive peroxide bond, which may pose health risks and alter the optical properties of aerosols.
