Wei Wang,Min juan Huang,Yuan Kang,Hong-Sheng Wang,Anna Oi Wah Leung,Kwai Chung Cheung,Ming Hung Wong,Ming Hung Wong +7 more
TLDR
Ninety-six urban surface dust samples collected from Guangzhou, a typical urban center in South China, were analyzed for PAHs, and four hotspots with highest ∑PAHs were identified via kriging prediction mapping, representing the highly-urbanized regions.About:

Heavy metals and polycyclic aromatic hydrocarbons: pollution and ecological risk assessment in street dust of Tehran.
TL;DR: Investigation of street dust samples from four major streets in eastern and southern Tehran revealed that traffic and related activities, petrogenic and pyrogenic sources are likely to be the main anthropogenic sources of heavy metals and PAHs in Tehran dust.

Ecological and human health hazards of heavy metals and polycyclic aromatic hydrocarbons (PAHs) in road dust of Isfahan metropolis, Iran.
Naghmeh Soltani,Behnam Keshavarzi,Farid Moore,Tahereh Tavakol,Ahmadreza Lahijanzadeh,Nemat Jaafarzadeh,Maryam Jafarkhani Kermani +6 more
TL;DR: Estimated results of ILCR indicate that Isfahan residents are potentially exposed to high cancer risk via both dust ingestion and dermal contact and possible ecological risk reveals that among the analyzed metals, Cd and Pb, have a higher potential ecological risk.

Removal of polycyclic aromatic hydrocarbons in aqueous environment by chemical treatments: a review.
TL;DR: Combined processes, particularly AOPs coupled with biological treatments, seem to be one of the best solutions for the treatment of effluents containing PAHs.

Polycyclic aromatic hydrocarbons (PAHs) concentration levels, pattern, source identification and soil toxicity assessment in urban traffic soil of Dhanbad, India.
TL;DR: The results indicated that vehicular emission was the major source for PAHs contamination with moderate effect of coal combustion and biomass combustion andcinogenic potency of PAH load in traffic soil was nearly 6.15 times higher as compared to the control/rural soil.
Journal ArticleDOI
Status, source and health risk assessment of polycyclic aromatic hydrocarbons in street dust of an industrial city, NW China.
TL;DR: The correlation analysis suggested that the total organic carbon was only slightly affected the PAH accumulation in street dust, and the isomer ratios and principal component analysis indicated that the dust-borne PAHs were derived primarily from the combustion of biomass, coal and petroleum emission.

PAHs in the Fraser River basin: a critical appraisal of PAH ratios as indicators of PAH source and composition

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: 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 sources of PAHs to ambient air in Baltimore, MD, were determined by using three source apportionment methods, principal component analysis with multiple linear regression, UNMIX, and positive matrix factorization.

Geochemistry and risk assessment of street dust in Luanda, Angola: A tropical urban environment
TL;DR: A total of 92 samples of street dust were collected in Luanda, Angola, were sieved below 100 μm, and analysed by ICP-MS for 35 elements after an aqua-regia digestion as discussed by the authors.

TL;DR: PAHs and hopanes fingerprints indicated that used crankcase oil is one of the major contributors of the sedimentary PAHs, and other biomarker profiles confirmed the hypothesis of the input from street dust contained the leaked crank case oil.
