Kinetics of NO3 Uptake on Pyrene as a Representative Organic Aerosols

Global Cancer Risk from Unregulated Polycyclic Aromatic Hydrocarbons

“…Because the exact mechanism is unknown, we simulated it here using a single-step reaction. Laboratory studies find that the yield of N-PAHs from this process ranges 0.04% (Zelenov et al, 2018)-100% (Ringuet et al, 2012). In our model, we assumed a fixed N-PAH formation yield, and chose 100% in order to bound this reaction pathway; despite this maximal assumption, our model still underestimates the nitro-PYR/PYR ratio as discussed above.…”

“…N-PAHs have been detected in a variety of environments, from urban (Albinet et al, 2007;Elzein et al, 2019) to remote (Drotikova et al, 2020;Lammel et al, 2017). The chemical formation of N-PAHs in the atmosphere has been simulated in regional-scale (Mulder et al, 2019) and global-scale (Wilson, 2020) atmospheric modeling studies; those studies, however, did not include a key particle-phase reaction with the nitrate radical (NO 3 ) that laboratory studies suggest could be an extremely efficient source of N-PAHs (Zelenov et al, 2018;P. Zhang et al, 2014).…”

Furthermore, as prior studies did not perform human health impact assessments, the importance of N‐PAHs in the context of human health, as well as in relation to other advancements in this field, are both unknown.…”
