Short summary
This work for the first time demonstrated that organonitrogen compounds (NOC) can be formed efficiently via the uptake of ammonia by newly formed secondary organic aerosol using a smog chamber equipped with a HR-ToF-AMS. Based on the measured kinetics, this study suggests that light absorption by NOC in atmospheric particles may be important in regions where the BC contribution is minimal and NOC from ammonia should be considered with respect to overall deposition of nitrogen to ecosystems.
