TLDR
The sources identified were Vehicular emissions, natural gas combustion, petrol emissions and evaporative/unburned fuel were the sources contributing 56%, 21%, 15% and 8% of the total PAHs emissions, respectively, all of which need to be considered for any pollution control measures implemented in urban areas.About:

Exposure to polycyclic aromatic hydrocarbons in atmospheric PM 1.0 of urban environments: Carcinogenic and mutagenic respiratory health risk by age groups
Dayana Milena Agudelo-Castañeda,Elba Calesso Teixeira,Ismael L. Schneider,Sheila Rincón Lara,Luis F.O. Silva +4 more
TL;DR: Research suggests to include carcinogenic and mutagenic PAHs in future studies of environmental health risk due to their capacity to associate to PM10.0.

Improving risk management by using the spatial interaction relationship of heavy metals and PAHs in urban soil.
Shaohua Wu,Shenglu Zhou,Haijun Bao,Dongxiang Chen,Chunhui Wang,Baojie Li,Guijie Tong,Guijie Tong,Yujie Yuan,Yujie Yuan,Baogen Xu +10 more
TL;DR: This study used bivariate local Moran's I to analyze the spatial interaction between heavy metals and PAHs, revealed the causes of spatial interaction patterns through PMF, and proposed a risk zoning approach for combined pollution in urban areas.

Organophosphate flame retardants (OPFRs) in indoor and outdoor air in the Rhine/Main area, Germany: comparison of concentrations and distribution profiles in different microenvironments
TL;DR: Three distinct groups for OPFRs were revealed, i.e., TiBP/TnBP, TEP/TCEP/TDCPP, and TCPP, whose concentrations were closely associated with the distribution profiles and pollution characteristics of materials predominating in different indoor microenvironments.

Airborne particulate matter (PM2.5) triggers autophagy in human corneal epithelial cell line
Qiuli Fu,Danni Lyu,Lifang Zhang,Zhenwei Qin,Qiaomei Tang,Houfa Yin,Xiaoming Lou,Zhijian Chen,Ke Yao +8 more
TL;DR: The results indicate the potential role of autophagy in the treatment of PM2.5-induced ocular corneal diseases and provide direct evidence for the cytotoxicity, possibly involving an autophagic process, of PM 2.5 in HCECs.

TL;DR: The distribution patterns, infiltration and health risk assessment of PM2.5-bound PAHs in indoor and outdoor air done in Harbin city, northeastern China showed that, the greatest seasonal variability was attributed to high molecular weight compounds (HMWPAHs).

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

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.

TL;DR: The carcinogenicity of polycyclic aromatic hydrocarbons (PAHs) is associated with the complexity of the molecule, and with metabolic activation to reactive diol epoxide intermediates and their subsequent covalent binding to critical targets in DNA.

Source Apportionment of Atmospheric Polycyclic Aromatic Hydrocarbons Collected from an Urban Location in Birmingham, U.K.
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.

PAH source fingerprints for coke ovens, diesel and, gasoline engines, highway tunnels, and wood combustion emissions
TL;DR: In this article, a modified high-volume sampling method (PS-1 sampler) was employed to collect airborne polyaromatic hydrocarbons (PAHs) in both the particulate and gas phases.
