“…Mahasakpan et al [ 14 ] assessed Thailand’s air quality, revealing that mean B[ a ]P concentrations (adsorbed at particle phase) during partial and strong haze periods were 0.052 and 0.095 ng/m 3 in PM 2.5 fraction, respectively, which was 6 and 11 times higher in comparison to the normal period (0.009 ng/m 3 ). Disturbingly, B[ a ]P adsorbed on PM1 (the particles that can penetrate deeply into the respiratory tract and enter the circulatory system) contributed to 74.0–91.1% of B[ a ]P-PM 2.5 fraction.…”

Benzo[a]pyrene (B[a]P) is the main representative of polycyclic aromatic hydrocarbons (PAHs), and has been repeatedly found in the air, surface water, soil, and sediments. It is present in cigarette smoke as well as in food products, especially when smoked and grilled. Human exposure to B[a]P is therefore common. Research shows growing evidence concerning toxic effects induced by this substance. This xenobiotic is metabolized by cytochrome P450 (CYP P450) to carcinogenic metabolite: 7β,8α-dihydroxy-9α,10α-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE), which creates DNA adducts, causing mutations and malignant transformations. Moreover, B[a]P is epigenotoxic, neurotoxic, and teratogenic, and exhibits pro-oxidative potential and causes impairment of animals’ fertility. CYP P450 is strongly involved in B[a]P metabolism, and it is simultaneously expressed as a result of the association of B[a]P with aromatic hydrocarbon receptor (AhR), playing an essential role in the cancerogenic potential of various xenobiotics. In turn, polymorphism of CYP P450 genes determines the sensitivity of the organism to B[a]P. It was also observed that B[a]P facilitates the multiplication of viruses, which may be an additional problem with the widespread COVID-19 pandemic. Based on publications mainly from 2017 to 2022, this paper presents the occurrence of B[a]P in various environmental compartments and human surroundings, shows the exposure of humans to this substance, and describes the mechanisms of its toxicity.

“…In this study, the BaP/BghiP ratio was more than 2 times higher during the cold season compared to the warm one. Therefore, vehicular exhaust emission is expected to play an important role in high-molecular-weight PAH pools, depending on season and meteorological conditions, as observed in many previous studies 4,6,7,11,49 . S2 shows Spearman's rank correlation analysis (Rs) performed to assess the statistically significant dependences between concentrations of individual PAH isomers in the gas (only Naph, Acy, Ace) and particle phases, and other parameters at the 95% confidence level (p < 0.05).…”

“…A decrease in Σ 16 PAH concentrations identified on 7 May 2020, 5 Oct 2019 and 9 Jul 2019 was also attributed to high precipitation amount (22.3 mm, 19.0 mm, and 21.0 mm), meanwhile, values of PAH losses were slightly lower compared to case study no.1 and accounted for 44%, 42%, and 21%, respectively (Table S3, no. 4,6,14). It should be highlighted that these cases were mainly attributed to northern flow from Scandinavia (marine sector), indicating that less polluted air masses were transported to the receptor domain.…”

“…Sources of PAHs can be structurally identified and apportioned based on different methods, i.e. positive matrix factorization 5,6 ; diagnostic ratios [7][8][9][10][11] ; principal component analysis 12,13 ; and hybrid receptor models 14 . Many other studies recognized that other environmental parameters should be examined to address the seasonal variability, levels and processes of semivolatile aromatic hydrocarbons 15 .…”

In this study, 16 USEPA-prioritized PAHs in gas- and particle-phase (PAHg+p), associated chemical and meteorological parameters, and backward trajectory simulations were explored in a coastal city in Poland, between April 2019 and May 2020. This study reports several important aspects of PAHg+p, i.e. variation, composition, distribution profiles, impact of weather conditions, and correlation analysis between target PAH compounds and influencing inorganic gaseous pollutants. Specifically, higher and more variable concentrations of total PAHg+p (mean ± SD, ng m−3) were observed during winter (36.38 ± 24.19) compared to autumn (22.3 ± 17.44), summer (21.52 ± 13.30) and spring (19.90 ± 13.13). A distribution profile of parent PAHg+p was as follows: 3-ring > 4-ring > 2-ring > 5-ring > 6-ring, although their relative contribution to the total PAHs showed statistically significant differences between seasons (p < 0.05). Precipitation-driven loss of ΣPAHg+p was lower in the warm period than in the cold one, reflecting higher PAH concentrations in winter. A seasonal model-based analysis of incremental lifetime cancer risk showed a higher potential cancer risk for children than those for adult females and males. The adverse health impacts associated with PAH exposure via inhalation route indicate the need for implementation of pollution-control policies in this region.
