Real-world automotive emissions: Summary of studies in the Fort McHenry and Tuscarora Mountain tunnels. Final report
TL;DR: In this paper, two major vehicle emissions studies were conducted: one in Fort McHenry tunnel (under the Baltimore Harbor) in June 1992 and the other in the Tuscarora Mountain tunnel in southcentral Pennsylvania (Pennsylvania Turnpike) in September 1992 The cars at both sites tended to be newer than elsewhere and much better maintained as judged by low CO/CO2 ratios and other emissions characteristics.

Polycyclic aromatic hydrocarbons (PAHs) and their derivatives (oxygenated-PAHs, nitrated-PAHs and azaarenes) in size-fractionated particles emitted in an urban road tunnel
TL;DR: In this article, a sampling campaign of size segregated particulate matter (PM0.5, PM0.1, PM1-2) was carried out at two sites, one in a road tunnel (Braga, Portugal) and another at an urban background location in the neighbourhood.

Célia Alves,Margarita Evtyugina,Ana Vicente,Estela D. Vicente,Teresa Nunes,P. M. A. Silva,Márcio Duarte,Casimiro Pio,Fulvio Amato,Xavier Querol +9 more
TL;DR: Although the risk via inhalation of PAH was found to be insignificant, the PM10 from some roads can contribute to an estimated excess of 332 to 2183 per million new cancer cases in adults exposed via ingestion and dermal contact.

Size-segregated urban particulate matter: mass closure, chemical composition, and primary and secondary matter content.
TL;DR: Forty-nine components of ambient particulate matter (PM) in size-fractionated PM were investigated at an urban background site in Katowice in the non-heating season of 2012, finding that PM0.6 posed the greatest health hazard from the mixture of the 16 PAHs that it contained, PM1.6–40 was the next, and thehazard from thePM0.03–0.26-bound 16PAHs was the smallest.

TL;DR: In this article, a year-round sampling was performed at the University of Sao Paulo campus (20m) in Brazil to evaluate the sources of particulate air pollution and related health risks, and different chemical constituents, such as carbonaceous species, polycyclic aromatic hydrocarbons (PAHs), water-soluble ions, and biomass burning tracers were identified in order to evaluate health risks and to apportion sources.

The composition of the continental crust
TL;DR: In this paper, a new calculation of the crustal composition is based on the proportions of upper crust (UC) to felsic lower crust (FLC) to mafic lower-crust (MLC) of about 1.6:0.4.

Sources and properties of non-exhaust particulate matter from road traffic: a review.
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, 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.

Metal emissions from road traffic and the influence of resuspension: results from two tunnel studies
TL;DR: In this article, metal emissions from road traffic were studied in two heavily trafficked tunnels in Gothenburg, Sweden, and five runs were made in each tunnel, generally extending over several hours, during which air concentrations of metals in tunnel inlet and outlet, traffic flow and composition and air ventilation were determined.
