TL;DR: In this paper, the authors provided an assessment of black-carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and that is quantitative in providing best estimates and uncertainties of the main forcing terms: direct solar absorption; influence on liquid, mixed phase, and ice clouds; and deposition on snow and ice.

PAHs in the Fraser River basin: a critical appraisal of PAH ratios as indicators of PAH source and composition
Mark B. Yunker,Robie W. Macdonald,Roxanne Vingarzan,Reginald H. Mitchell,Darcy Goyette,Stephanie Sylvestre +5 more
TL;DR: In this paper, parent and alkyl PAHs were quantified in suspended particulates and sediments (345 samples) from the Fraser River system, British Columbia, Canada, and the best potential to distinguish natural and anthropogenic sources is exhibited by ratios of the principal mass 178, 202, 228 and 276 parent PAH, 1,7/2,6+1,7-DMP (dimethylphenanthrene), the phenanthrene/anthracene and fluoranthene/pyrene alkyal PAH series and several less commonly applied PA

Engines and nanoparticles: a review
TL;DR: In this article, a new HEI study showed that some low-emission diesel engines emit much higher concentrations of nanoparticles than older designs and other low-EMission designs, which has raised questions about whether nanoparticle (number based) emission standards should be imposed.

A technology-based global inventory of black and organic carbon emissions from combustion
Tami C. Bond,Tami C. Bond,Tami C. Bond,David G. Streets,Kristen F. Yarber,Sibyl M. Nelson,Jung Hun Woo,Zbigniew Klimont +7 more
TL;DR: This article presented a bottom-up estimate of uncertainties in source strength by combining uncertainties in particulate matter emission factors, emission characterization, and fuel use, with uncertainty ranges of 4.3-22 Tg/yr for BC and 17-77 Tg /yr for OC.

An Association between Air Pollution and Mortality in Six U.S. Cities
Douglas W. Dockery,C A Pope rd,X Xu,John D. Spengler,James H. Ware,Martha E. Fay,Benjamin G. Ferris,Frank E. Speizer +7 more
TL;DR: It is suggested that fine-particulate air pollution, or a more complex pollution mixture associated with fine particulate matter, contributes to excess mortality in certain U.S. cities.

Particle and gas dry deposition: A review
TL;DR: In this paper, the authors summarized numerical values of particle and gas dry deposition velocities and recommended a model developed by Sehmel and Hodgson for numerical prediction purposes, which was used for particle prediction purposes.
