TLDR
Investigating the sources of organic pollutants associated with fine and coarse atmospheric particulate matter in Doha, Qatar based on an eight-month sampling campaign found that both long-range and local sources have a significant impact on atmospheric carbonaceous particles in the area, depending on the wind conditions.Abstract:
In this study, we investigated the sources of organic pollutants associated with fine (PM2.5) and coarse (PM2.5–10) atmospheric particulate matter in Doha, Qatar based on an eight-month sam...read more

Atmospheric particle-bound polycyclic aromatic hydrocarbons, n-alkanes, hopanes, steranes and trace metals: PM2.5 source identification, individual and cumulative multi-pathway lifetime cancer risk assessment in the urban environment
TL;DR: The estimated total cumulative cancer risk comprising all toxic PAHs, besides those included in the priority list, and metals was higher than the USEPA's threshold by a factor of eight, denoting a potential risk for long-term exposure of a population in the urban environment.

High-time-resolution PM2.5 source apportionment based on multi-model with organic tracers in Beijing during haze episodes.
TL;DR: It is suggested that combining receptor model-based source apportionment with air quality model has practical significance for understanding the causes of haze episodes, setting city-specific emission reduction measures and improving air quality in the Beijing-Tianjin-Hebei (BTH) region.

Health Effects Associated with PM2.5: a Systematic Review
TL;DR: Systematic review of studies conducted globally in the past 5 years revealed that PM2.5 and other air pollutants have been found to be associated with increased mortality and morbidity due to respiratory, cardiovascular, cerebrovascular disorders and diabetes, however, most of the total studies were carried out in the high-income countries (HICs) despite the fact that PM 2.5 concentrations are higher in the LMICs.

TL;DR: In this paper, mass closure analysis and positive matrix factorization (PMF) model along with detailed wind direction analysis for quantifying and identifying the probable sources of both PM2.5 and PM10 were applied to measure chemical constituents (including trace elements, organic and elemental carbon (OC/EC), and water-soluble ions).

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

Carbonaceous aerosol in urban and rural European atmospheres: estimation of secondary organic carbon concentrations
TL;DR: In this paper, the fraction of particulate organic carbon with a secondary origin in gas/particle conversion of volatile organic compounds was estimated from the minimum ratio between particulates organic and black carbon, which occurred during periods of reduced photochemical activity.
