Carbonyls in urban fog, ice fog, cloudwater and rainwater
Abstract Formaldehyde, acetaldehyde, propanal, acetone + acrolein, n-butanal, 2-butanone, n-pentanal, n-hexanal and benzaldehyde have been identified in fog, ice fog, mist, cloudwater and rainwater samples collected at urban locations in California (Los Angeles) and Alaska (Fairbanks). Formaldehyde concentrations, up to ~ 2 mg ℓ−1, were highest in urban fog and ice fog samples. Concentrations of other carbonyls occasionally approached or exceeded that of formaldehyde. The results are briefly discussed in terms of scavenging of gas-phase atmospheric carbonyls.
