Iso- and Anteiso-Alkanes: specific tracers of environmental tobacco smoke in indoor and outdoor particle-size distributed urban aerosols
Article Abstract:
Iso- and anteiso-alkanes are the most suitable tracers for particulate environmental tobacco smoke (ETS) emissions in indoor and outdoor particle-size distributed urban aerosols when conjointly used with n-alkanes and PAHs. ETS is the material released into the ambient atmosphere by smoking tobacco products. The suitability of iso- and anteiso-alkanes is due to their specificity, their nonreactive character, their association with the accumulation range mode particles, and therefore, their long atmospheric residence time.

Iso- and Anteiso-alkanes: specific tracers of environmental tobacco smoke in indoor and outdoor particle-size distributed urban aerosols
Article Abstract:
Branched iso- and anteiso-alkenes were shown to be good tracers of environmental tobacco smoke both in indoor and outdoor tobacco smoke determinations. Some of the qualities that make iso- and anteiso-alkenes better tracers than the conventional n-alkenes and polyaromatic hydrocarbon tracers are the non-reactive character of the alkenes, their specificity and long atmospheric residence times, which render the substances readily distinguishable using gas chromatography.

Oxocarboxylic and alpha, omega-dicarboxylic acids: photooxidation products of biogenic unsaturated fatty acids present in urban aerosols
Article Abstract:
Research has investigated the occurrence of oxocarboxylic and alpha, omega-dicarboxylic acids in airborne particles collected at Heraclion, Crete between April and August, 1991. Analysis aimed to determine the photooxidation products of unsaturated fatty acids with oxidants in the atmosphere. Analysis identified alkanoic acids in free and salt form.
