Source specificity and atmospheric processing of airborne PAHs: Implications for source apportionment
TL;DR: In this article, a review examines two of the assumptions necessary for conventional ratio- or profile-based source apportionment methods to be valid for polycyclic aromatic hydrocarbons (PAHs).
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.

Application of chemometrics to analysis of soil pollutants
TL;DR: In this paper, an overview of the application of chemometrics techniques to the investigation of soils contaminated by polycyclic aromatic hydrocarbons (PAHs) and metals, because these two important and very diverse groups of pollutants are ubiquitous in soils.

Experimental investigation of the performance and emissions of a heavy-duty diesel engine fueled with waste cooking oil biodiesel/ultra-low sulfur diesel blends
TL;DR: In this article, the emissions of polycyclic aromatic hydrocarbons (PAHs), carcinogenic potencies and regulated matters, and brake specific fuel consumption from a heavy-duty diesel engine under the US-HDD transient cycle were investigated.

Effects of vehicle type and fuel quality on real world toxic emissions from diesel vehicles
TL;DR: In this paper, emissions of a range of toxic compounds are reported using in-service vehicles which were tested using urban driving cycles developed for Australian conditions, including volatile organic compounds (VOCs), benzene and aldehydes, and polycyclic aromatic hydrocarbons (PAHs).

Toxic equivalency factors (TEFs) for polycyclic aromatic hydrocarbons (PAHs).
Ian C.T. Nisbet,Peter K. LaGoy +1 more
TL;DR: This paper evaluates several approaches to allow the relative potency of the different PAHs to be considered in a site-specific risk assessment and presents a modified version that it feels more accurately reflects the state of knowledge on the Relative potency of these compounds.

Sources of fine organic aerosol. 2. Noncatalyst and catalyst-equipped automobiles and heavy-duty diesel trucks
TL;DR: In this article, the authors search for conservative marker compounds suitable for tracing the presence of vehicular particulate exhaust emissions in the urban atmosphere, compile quantitative source profiles, and study the contributions of fine organic particulate vehicular exhaust to the Los Angeles atmosphere.

Measurement of emissions from air pollution sources. 2. c1 through c30 organic compounds from medium duty diesel trucks
TL;DR: In this article, a two-stage dilution source sampling system was used to quantify gas and particle-phase tailpipe emissions from late-model medium duty diesel trucks using a two stage dilution sampling system.

Ultrafine (nanometre) particle mediated lung injury
TL;DR: In this paper, a sequence of events following pulmonary deposition of ultrafine particles can be hypothesised, based on studies to date, which can be seen as an important factor in stimulating inflammation and interstitial transfer.

TL;DR: In this article, the authors quantified polycyclic aromatic hydrocarbon (PAH) emissions in gasoline and diesel fuel samples collected in summer 1997 in northern California and found that Naphthalene was the predominant PAH in both fuels.
