TLDR
The contribution of atmospheric deposition to PAH concentrations in the sediments was estimated to be 30% to 40% in the coastal regions of South China as discussed by the authors, and the annual mean washout ratio, defined as the ratio between the particle-associated concentrations of PAHs in precipitations and aerosols, was 3.4 × 105 in this study.About:

TL;DR: The results obtained showed that most of these compounds are pervasive in all the studied environmental matrices, especially in some hotspot areas, such as the Bagnoli Brownfield Site and the infamous "Triangle of the Death", where unwanted ecological risk conditions for PAHs and Endosulfan were determined.

TL;DR: Overall, the lung cancer risk in China and Vietnam were higher than that in Japan, South Korea, Vietnam, and India, and significant positive correlations were found between PAH concentrations and atmosphere aerosol optical depth.

Characterization and source apportionment of PM2.5-bound polycyclic aromatic hydrocarbons from Shanghai city, China.
TL;DR: The trajectory clustering and potential source contribution function (PSCF) and concentration weighted trajectory (CWT) models showed clearly that air parcels moved from west had highest concentrations of PM2.5, total PAHs and high molecular weight (HMW)PAHs, while small differences were found among all five clusters in low molecular weight PAHS.

Long term observations of PM2.5-associated PAHs: Comparisons between normal and episode days
TL;DR: The pollution characteristic of fine particular matter (PM25) and associated polycyclic aromatic hydrocarbons (PAHs) are currently drawing a great deal of interest because of their influence on environment and health as mentioned in this paper.
Journal ArticleDOI
An overview of particulate dry deposition: measuring methods, deposition velocity and controlling factors
TL;DR: In this paper, the authors provide a technical overview of the current state of dry deposition and limitations of various measurement methods, and various mathematical models used to predict dry deposition velocity are discussed.

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

TL;DR: In this paper, the authors assess current data in this area, develop global scale estimates of the atmospheric fluxes of trace elements, mineral aerosol, nitrogen species, and synthetic organic compounds to the ocean; and compare the atmospheric input rates of these substances to their input via rivers.

Evaluation of sediment contamination by polycyclic aromatic hydrocarbons in the Gironde estuary
TL;DR: In this paper, surface sediments, collected in the Gironde estuary during February and October 1993, were analysed for polycyclic aromatic hydrocarbons (PAHs) and the aromatic fractions were separated by liquid chromatography of the extracts and analysed by gas chromatography/mass spectrometry (GC/MS).

TL;DR: In this paper, concentrations of polynuclear aromatic hydrocarbons (PAHs) were reported in relation to particle size for aerosols of remote marine areas, and the HC concentrations were found to be dependent on the origin of the air masses.

A Review on Polycyclic Aromatic Hydrocarbon (PAH) Emissions from Energy Generation
TL;DR: In this article, the state of the art on their sampling and analytical procedures are commented, and the influence of the fuel, fossil and nonfossil fuels, the combustor type and the combustion variables are analyzed concerning polycyclic aromatic hydrocarbons (PAH) formation and emission in solid/gaseous phase.
