TL;DR: It is concluded that with the exception of brake dust particles which may be identified from their copper (Cu) and antimony (Sb) content, unequivocal identification of particles from other sources is likely to prove extremely difficult, either because of the lack of suitable tracer elements or compounds, or of the interactions between sources prior to the emission process.

TL;DR: In this paper, a seasonal sampling campaign was undertaken at an urban location in Birmingham, U.K., in which high-volume samplers were used to collect particulate and vapor-phase polycyclic aromatic hydrocarbons (PAHs) by means of filter papers and polyurethane foam plugs.

TL;DR: In this article, the authors synthesize data on aerosol physical characteristics, which were obtained in European aerosol research activities at free-troposphere, natural, rural, near-city, urban, and kerbside sites over the past decade.

TL;DR: Overall, the data presented provides little support for the idea that any single major or trace component of the particulate matter is responsible for the adverse effects.

TL;DR: In this paper, the authors reviewed the nature of the particle emissions from road vehicles including both exhaust and non-exhaust (abrasion and re-suspension sources) and briefly reviewed the various methods available for quantification of the road traffic contribution.
