“…Table 2). Levels of the total PAHs in the studied soils were ranged from 5.1 to 297.0 ng/g, and such levels have been reported in agriculture soils in Korean west plain (23 -303 ng/g) (Nam et al, 2003) and in cultivated Polish soils (20 -300 ng/g) (Kabata-Pendias et al, 1995), but higher than those in rural soils (10 ng/g) (Edward, 1987). In comparison with other Chinese wastewater irrigation areas, the PAHs levels in the study were lower than those in Shenyang (Song et al, 1997) and Tianjin (Wang et al, 2003a,b) of China, where untreated wastewater were directly applied in both of the two places.…”

“…In our studies, the results are similar. With the total organic carbon concentration decreasing from 20.09 to 2.5 mg/g soil, the total PAH concentrations Nam et al 2003 This study Chen et al 2005Ma et al 2008 No. of samples in the rural soils from Dongjiang River Basin decrease from 231 to 23.5 μg/kg.…”

“…In addition, a comprehensive comparison was conducted between the PAH concentrations in this study and those in urban and rural soils from other global regions such as Hong Kong, South Korea, Norway, and UK (Nam et al 2003;Zhang et al 2006;Nam et al 2008) (Table 1). PAH concentrations (23.5-231 μg/kg ) in the rural soils from the Dongjiang River basin are much higher than those in Hong Kong (7-200 μg/kg) but much lower than those in Norway (8.6-1,100 μg/kg).…”

Purpose A comprehensive study was conducted to investigate the presence of polycyclic aromatic hydrocarbons (PAHs) in Dongjiang River Basin (DRB) soils and to evaluate their sources and ecological and health risk. In addition, factors affecting the distribution and fate of PAHs in the soils such as emission density, soil organic matter, degradation, etc. were studied. Materials and methods Surface soil (0-20 cm) samples from 30 sampling sites in the rural areas of DRB were collected and analyzed for 17 polycyclic aromatic hydrocarbons (16 EPA priority PAHs and perylene). Positive matrix factorization model was used to investigate the source apportionment of these PAHs, and an incremental lifetime cancer risk (ILCR) was used to estimate the integrated lifetime risks of exposure to soil-borne PAHs through direct ingestion, dermal contact, and inhalation collectively. Results and discussion The total PAH concentrations in the rural soils in DRB range from 23.5 to 231 μg/kg with a mean concentration of 116 μg/kg. The predominant PAHs in the rural soils were naphthalene, fluoranthene, phenanthrene, and benzo(b)fluoranthene. Cluster analysis was performed to classify the soil PAHs into three clusters, which could be indicative of the soil PAHs with different origins and different properties. Source apportionment results showed that coal, biomass, oil, commercial creosotes, and vehicle contributed 24 %, 24 %, 17 %, 17 %, and 18 % of the total soil PAH burden, respectively. The ILCR results indicated that exposure to these soil-borne PAHs through direct ingestion, dermal contact, and inhalation collectively produces some risk. Conclusions PAHs in the soils of the DRB will produce long-term influences on rivers and oceans via soil erosion and river transport. Therefore, PAHs in rural soils of DRB have potential impacts on the water supply and human health risk.

“…Soil system is considered the most important long-term repository for PAHs and is also considered to be a steady indicator of the environmental pollution state (Nam et al, 2003;Mueller and Shann, 2006). PAHs in soils may further accumulate in vegetables and other biota via food chains (Li et al, 2008).…”

As a developing country, the economic and population growth rates in Ghana over the past few years have seen tremendous increase. The growing rate of industrialization is gradually leading to contamination and deterioration of the environment and pollution is likely to reach disturbing levels. Surface soil samples were collected randomly from 36 communities in the Kumasi metropolis, Ghana, to determine the concentrations, distribution, sources and toxic potential of emission of polycyclic aromatic hydrocarbons (PAHs) since no such comprehensive study has been conducted. The mean concentration of total PAHs in the surface soils in each community ranged from 14.78 at Ahinsan to 2084 ng/g dry weight at Adum with an average of 442.5 ± 527.2 ng/g dry weight. Diagnostic ratios and chemical mass balance models of the results showed that PAHs in surface soil samples from the study area were mainly from fuel combustion.Carcinogenic potency of PAHs load from the city centre was approximately 150 times higher as compared to a pristine site, Kwame Nkrumah University of Science and Technology's Botanical Garden. BaP, a human carcinogen, contributed 70% of the total PAHs toxicity level from the city centre of Kumasi.
