“…In line with these results, Dong and Lee (2009) and Wang et al (2011) pointed at slow-moving vehicular traffic and weak dispersion as causes for the accumulation pattern. A positive correlation between PAH content and traffic intensity has also been proven (Cao et al, 2017;Ha et al, 2012). Values of ΣPAH in this study are in line with results by Jancsek-Turóczi et al ( 2013) (1.46-3.48 μg g − 1 PM 1-10 , and 5.53-35.57 μg g − 1 PM 1 , respectively).…”

“…The enrichment of street dust in comparison with urban soil from Tyumen was observed for MMW and HMW PAHs, while for LMW PAHs, except for NAP, were close. MMW and HMW PAHs are considered to be strongly associated with vehicular transport (Cao et al 2017b) and NAP with petroleum sources (Bao et al 2018).…”

This study investigated levels and sources of pollution and potential health risks associated with potentially toxic elements (PTEs) and polycyclic aromatic hydrocarbons (PAHs) in urban street dust collected from Tyumen city, a large transport centre with one of the highest motorization rates in Russia. Twenty street dust samples were collected from four grades of roads in five different land use areas.Research methods included measurements of physical and chemical properties of street dust, concentrations of 18 PTEs using inductively coupled plasma mass spectrometry, 12 PAHs using high-performance liquid chromatography, and statistical analysis of the data. Concentrations of Ni, Cr, Sb, and Mo, as well as medium and high molecular weight PAHs in urban street dust, were notably higher than in soils within the city, which indicates that transport is the main source of these elements. Concentrations of Cu, Cd, Pb, Zn, Mn, and As in street dust of Tyumen were lower compared to many large cities, while Cr, Ni, and Co were higher. Concentrations of PAH were comparable to other large nonindustrial cities. Total contamination of street dust by both PTEs and PAHs showed more robust relationships with the number of roadway lanes rather than land use. The estimated carcinogenic risks were low in 70% of samples and medium in 30% of samples. Noncarcinogenic risks were attributed to exposure to Co, Ni, V, and As. The total noncarcinogenic risk for adults was found to be negligible, while the risk was found to be moderate for children.

“…For example in a study of PM10 and PM 2.5 from Tonglin city China [177] showed seasonal variations caused by biomass burning; ii) Vehicular emissions [104, 108, 111-113, 116, 119, 125, 126, 139, 140, 143, 144, 147, 148, 152, 154, 155, 157, 159-162, 165, 171, 176-197]. Cao and co-workers [126] analysed 34 road dust samples collected from Xinxiang, China. Total PAHs concentrations indicated a significant positive correlation existed between PAH contamination and traffic density.…”

Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds consisting of two or more fused aromatic rings and are probably one of the most studied groups of organic chemicals in environmental research. PAHs originate mainly from anthropogenic processes, particularly from incomplete combustion of organic fuels. PAHs are distributed widely in particulate matter. Due to widespread sources and persistent characteristics, PAHs disperse through atmospheric transport and exist almost everywhere. Human beings are exposed to PAH mixtures in gaseous or particulate phases in ambient air. Long-term exposure to high concentrations of PAHs is associated with adverse health problems. This review identifies the main research and development themes in the measurement and occurrences of PAHs in dusts and particulates using a new approach to carrying out a literature review where many peer-review publications have been produced. The review extracts the most important research themes from a literature search using a combination of text mining and a more detailed review of selected papers from within the identified themes.
