Phenolic compounds (PhCs) are crucial atmospheric pollutants typically emitted by biomass
burning and receive particular concerns considering their toxicity, light-absorbing properties …

Aqueous-phase reactions of α-dicarbonyls with ammonium or amines have been identified
as important sources of secondary brown carbon (BrC). However, the identities of most …

Brown carbon (BrC) has attracted widespread attention because of its strong absorption of
solar radiation in the ultraviolet-visible wavelength range, which causes adverse impacts on …

Vanillin (VL), a phenolic aromatic carbonyl abundant in biomass burning emissions, forms
triplet excited states (3 VL∗) under simulated sunlight leading to aqueous secondary …

The light-absorbing organic aerosol (OA) constitutes an important fraction of absorbing
components, counteracting major cooling effect of aerosols to climate. The mechanisms in …

Biomass burning emits large amounts of phenols, which can partition into cloud/fog drops
and aerosol liquid water (ALW) and react to form aqueous secondary organic aerosol …

Aqueous-phase reactions of α-dicarbonyls with amines or ammonium have been identified
as important sources of secondary brown carbon (BrC). However, the kinetics of BrC …

Incense burning is a common ritual in Asian communities, and it emits massive amounts of
particles. These particles can undergo atmospheric aging upon exposure to sunlight and …

Abstract Aromatic carbonyls (eg, methoxybenzaldehydes), an important class of
photosensitizers, are abundant in the atmosphere. Photosensitization and nitrate-mediated …

This study examined the effects of simulated solar irradiation on a model system of
atmospheric aqueous secondary organic aerosol (aqSOA) formed from oxidation of guaiacyl …
