“…The result was in agreement with the independent investigations of Ma et al (2005) and Jiao et al (2009) who reported the median concentrations of PAHs in pristine soils of Beijing as 228 ng g À1 and 260 ng g…”

a b s t r a c tWe investigated the polycyclic aromatic hydrocarbons (PAHs) contents in 68 soils samples collected at housing developments that represent different length of development periods across Beijing. Based on the data, we derived a mass balanced mathematical model to simulate the dynamics of PAH accumulations in urban soils as affected by the urban developments. The key parameters were estimated by fitting the modified mass balance model to the data of PAH concentrations vs. building age of the sampling green area. The total PAH concentrations would increase from the baseline of 267 ng g À1 to 3631 ng g À1 during the period of 1978e2048. It showed that the dynamic changes in the rates of accumulations of light and heavy PAH species were related to the shifting of sources of fuels, combustion efficiencies, and amounts of energy consumed during the course of development.

“…It is known that HMW PAHs are major carcinogenic PAHs (Maliszewska-Kordybach et al 2009) and are dangerous for field crops. It is notable that BaP, which is one of the most dangerous PAH (Ma et al 2005) in the environment, was found in concentrations of about 3 mg kg −1 in some samples. A comparison of average PAH with standard values for underground water indicates that Na and An at depth 1 and Na, Phe, An, and Flu at depth 2 exceeded standard values.…”

“…Total PAH concentrations were higher at depth 2 than at depth 1. Some researchers like Mikkonen et al (2012) also found that the concentration of ΣPAHs increased as the depth increased, whereas Ma et al (2005) and Zhang et al (2013) concluded that PAH concentration in soil decreased at subsoil. Table 1 shows the average concentration of PAH compounds in two different agricultural regions (Hong Kong and Beijing).…”

“…Industrialization has also resulted in widespread pollution of soil (Telysheva et al 2011). In addition, soil contamination by organic matter such as aromatic compounds (Wong et al 2002;Ma et al 2005) has increased its toxicity, mutagenicity, carcinogenicity, and teratogenicity (Gao et al 2010). Soil consists of an inorganic phase and a biotic phase that includes bacteria, plants, and other animals.…”

Soil samples at two depths were collected and analyzed to determine the concentrations of 16 polycyclic aromatic hydrocarbons (PAHs), organic carbon, and soil pH. The Σ16PAHs were 0.13 to 3.92 mg kg(-1) at depth 1 and 0.21 to 50.32 mg kg(-1)at depth 2. The averages of the PAH compounds indicate that the area is contaminated with oil, and this pollution was greater at depth 2. Interpolation maps showed that the southern region, especially at depth 2, has been contaminated more by anthropogenic activity. The diagnostic ratios indicate several sources of pollution of the agricultural soil. A comparison of average PAHs and standard values revealed that higher molecular weight compounds in the topsoil (InP and BghiP) and subsoil (BaA, BkF, BaP, DBA, and BghiP) exceed standard values for farmland. The pH interpolation map for both depths showed that most of the area has alkaline soil from long-term irrigation with untreated urban wastewater.

“…Strong sorption, coupled with very low water solubility and very low vapor pressures, render leaching and volatilization an insignificant pathways with regard to the dissipation of PAHs (Park et al 1990). Although several hundreds of PAHs have been identified thus far, the majority of studies have focused specifically on the 15 to 17 better-known EPA priority PAHs due to their toxicological significance (Black 1983;Bauman 1984;Angerer et al 1997;Cho et al 2003;Ma et al 2005, Qiao et al 2006.…”

The wide-scale reclamation of tidal flats distributed throughout the western and southern coastal areas in Korea has been completed, in an effort to expand the available arable land. The present studies were conducted in order to characterize the concentrations and compositional patterns of selected PAHs, in order to obtain more information regarding environmental risk assessments for sustainable and environment-friendly agriculture in reclaimed tidelands and tidelands in South Korea. The PAH contents were low to moderate, relative to other urbanized regions of the world. Sigma PAHs ranged from 69.8 to 1,175.2 ng g(-1) in dry weight, with a mean value of 394.4 ng g(-1). Differences were observed in the Sigma PAHs concentrations between industrial complex areas and rural regions. The two dominant PAHs were identified as fluoranthene and pyrene. These compounds constituted 1.4 to 55.0% (mean, 33.4%) and 2.7 to 45.6% (mean, 22.0%) of the Sigma PAHs. Our correlation analysis revealed that the Sigma PAHs contents were associated significantly with the organic carbon content (R(2) = 0.86, P < 0.01) and the cation exchange capacity (CEC; R(2) = 0.89, P < 0.01) in the reclaimed tidelands and tidelands.
