Distribution, input pathway and soil–air exchange of polycyclic aromatic hydrocarbons in Banshan Industry Park, China

Association of soil polycyclic aromatic hydrocarbon levels and anthropogenic impacts in a rapidly urbanizing region: Spatial distribution, soil–air exchange and ecological risk

“…Our fugacity-based modeling shows that 3-ring PAHs (Acy, Ace, Flo, Phe and Ant) tend to evaporate from soil to air with escaping diffusive fluxes ranging from 0.79 to 713 μg m −2 yr −1 , whereas 5-and 6-ring PAHs (BaP, DahA, IcdP and BghiP) are likely to deposit from air to soil with deposition fluxes varying between 0.99 and 10.2 μg m − 2 yr − 1 (Table 2). These results were consistent with the findings of several previous studies, conducted in Beijing , Tibetan Plateau (Wang et al, 2014), Dalian (Wang et al, 2008) and Zhejiang Province (Zhong and Zhu, 2013) of China, and in Turkey (Bozlaker et al, 2008), that soil is a secondary source of low molecular weight PAHs, but a sink of high molecular weight PAHs. It is interesting to note that the mean escaping or deposition fluxes of Flu and Pyr ranged from 1.3 to 1.41 or from 0.17 to 1.7 μg m −2 yr −1 (Table 2), and the soilair fugacity fractions of Flu and Pyr ranged from 0.27 to 0.67 (Table S6), approximately within the range of 0.30-0.70 used to suggest the soilair equilibrium state of a target compound in a region (Harner et al, 2001;Meijer et al, 2003).…”

A review of airborne polycyclic aromatic hydrocarbons (PAHs) and their human health effects

“…The behavior of PAHs in the atmosphere depends on complex physico-chemical reactions, interactions with other pollutants, photochemical transformations, and dry and wet deposition (Delgado Saborit et al, 2010;Zhong and Zhu, 2013;Zhu et al, 2009). PAHs in the ambient air exist in vapor phase or adsorb into airborne particulate matter depending on the atmospheric conditions (ambient temperature, relative humidity, etc.…”

P-gp expression in brown trout erythrocytes: evidence of a detoxification mechanism in fish erythrocytes

“…For this purpose, we chose to test the action of B a P, which is a cytotoxic, genotoxic and carcinogenic model pollutant in the PAHs class. It has been found in air, water and soil3233. Moreover, B a P, like several other PAHs, has been shown to induce P-gp in other biological models of aquatic and atmospheric pollution51112.…”
