Polycyclic aromatic hydrocarbons (PAHs) and their derivates are mutagenic and carcinogenic substances widely distributed in the atmospheric environment. In this study, effective rate constants for heterogeneous reactions of NO3 radicals with five 4-ring PAHs [benzo[a]anthracene (BaA), chrysene (Ch),...
