“…This is because PAHs are sparingly soluble, readily adsorbed by soil particles, and resist degradation (Tang et al, 2005). It has been estimated that approximately 90% of total residues remain in the soil (Hu et al, 2013). Urban areas are very populated and are accompanied by an increased production of industrial waste, traffic pollution, and household garbage, which produce many PAHs and other pollutants that migrate into urban soils through dry and wet atmospheric deposition.…”

“…These are some of the most harmful environmental pollutants with respect to human health, and 16 PAHs were listed as pollutants with priority control by the United States Environmental Protection Agency (U.S. EPA) [ 5 , 6 , 7 , 8 , 9 ]. Some studies have found that soils bear more than 90% of the environmental load of PAHs and are a potential source and sink in the environment [ 10 , 11 , 12 , 13 , 14 ]. Therefore, it is necessary to explore the pollution of farmland soil PAHs by traffic emissions and to assess their environmental risks.…”

Recently, the rapid growth in vehicle activity in rapidly urbanized areas has led to the discharge of large amounts of polycyclic aromatic hydrocarbons (PAHs) into roadside soils and these compounds have gradually accumulated in the soil, which poses a serious threat to national food security and public health. However, previous studies did not clearly investigate the seasonal differences in PAH pollution of roadside soil by different highways. Therefore, based on field investigations, this study collected 84 soil surface samples to compare the pollution characteristics of 16 PAHs in farmland soils located near different roads in different seasons in Guangzhou, China. The results showed that the concentration of Σ16PAHs in farmland soils in spring (with a mean value of 258.604 μg/kg) was much higher than that in autumn (with a mean value of 157.531 μg/kg). There are differences in the PAH compositions in spring (4 ring > 3 ring > 5 ring > 6 ring) and autumn (4 ring > 5 ring > 6 ring > 3 ring). The proportion of 4–6 ring PAHs was much higher than 2–3 ring PAHs in both seasons. The spatial differences were significant. The sampling areas with higher concentrations of 16 PAHs were Tanbu Town, Huadu District (TB), Shitan Town, Zengcheng District (ST), and Huashan Town, Huadu District (HS), while the lowest concentration was in Lanhe Town, Nansha District (LH). The results of the diagnostic ratios showed that the main source of soil PAHs consists of a mixed source from petroleum and biomass combustion. The results from the total pollution assessment method and Nemerow index method indicated that the pollution levels of PAHs in the farmland soils indicated weak contamination. Our study provides a scientific basis for the prevention and control of soil pollution in farmlands near highways.

“…Once released into the environment, PAHs may undergo transportation over long distances through water and air and thus remain globally in soils, sediments, waters, and atmospheres (Daskalakis and O'Connor, 1995;Manariotis et al, 2011). PAHs are resistant to degradation and prone to be absorbed by soil particles (Wang et al, 2017;Wilcke, 2007), which makes soils capable to be an important "PAH sink", burying more than 90% of the environmental PAH loads (Hu et al, 2013b;Wild and Jones, 1995).…”

Urbanization-related changes over the last 20 years in occurrence, sources, and human health risks of soil PAHs in rural Tianjin, China

Polycyclic aromatic hydrocarbons (PAHs), one of the key pollutants in urban areas, have presented a great risk to the resident health. So far, however, studies in-depth on changes of local PAH emissions and associated health risks closely related to urbanization are scarce. Here, the concentrations of PAHs were determined in 57 surface soil samples obtained from two rural districts in 2018 in Tianjin, China. The sources, risks and the linkage between urbanization and PAH contamination of soil PAHs in 2018 were compared with the data in 2001 from a previous study to investigate the changes related to urbanization effects. The temporal changes in the concentrations and composition of PAHs for two districts were similar. The increased total concentrations of soil PAHs could be attributed to the fact that ANT and DahA became the dominated compounds, which was related to changes of the PAH sources. Results of the positive matrix factorization model suggest that the major sources of soil PAHs changed from coal combustion (32.9%), petroleum sources (32.1%), and tra c sources (22.1%) in 2001 to tra c sources (63.7%) and petroleum and biomass combustion (18.7%) in 2018.Results from incremental lifetime cancer risk (ILCR) model showed that the carcinogenic risk of soil PAHs to residents also increased from safe level to low level, and dermal contact was the prevailing pathway of PAH exposure. The increase in cancer risks were mainly related to the alterations of PAH sources.
