“…Capuano et al (2005) reported that the concentrations of total PAHs in soils impacted upon by a municipal solid waste incinerator decreased with depth from 318.9 µg kg -1 (10 cm) to 88.9 µg kg -1 (20 cm) to 74.1 µg kg -1 (30 cm). Similarly, Banger et al (2010) reported comparable decreases over three consecutive 15 cm depths of 2,364 µg kg -1 to 839-1,104 µg kg -1 to 251-456 µg kg -1 in a commercial area soil. The majority of these studies, by reporting a snapshot reflecting the persistent input of PAHs at contaminated sites highlight the ability of PAHs to contaminate soil at various depths but do not focus on temporal variation and only briefly consider the underlying factors governing vertical mobility.…”

Polyaromatic hydrocarbons (PAHs) are emitted from a variety of sources and can accumulate on and within surface soil layers. To investigate the level of potential risk posed by surface contaminated soils, vertical soil column experiments were conducted to assess the mobility, when leached with simulated rainwater, of six selected PAHs (naphthalene, phenanthrene, fluoranthene, pyrene, benzo(e)pyrene and benzo(ghi)perylene) with contrasting hydrophobic characteristics and molecular weights/sizes. The only PAH found in the leachate within the experimental period of 26 days was naphthalene. The lack of migration of the other applied PAHs were consistent with their low mobilities within the soil columns which generally parallelled their log K oc values. Thus only 2.3% of fluoranthene, 1.8% of pyrene, 0.2% of benzo(e)pyrene and 0.4% of benzo(ghi)perylene were translocated below the surface layer. The PAH distributions in the soil columns followed decreasing power relationships with 90% reductions in the starting levels being shown to occur within a maximum average depth of 0.94 cm compared to an average starting depth of 0.5 cm. A simple predictive model identifies the extensive time periods, in excess of 10 years, required to mobilise 50% of the benzo(e)pyrene and benzo(ghi)perylene from the surface soil layer. Although this reduces to between 2 and 7 years for fluoranthene and pyrene, it is concluded that the possibility of surface applied PAHs reaching and contaminating a groundwater aquifer is unlikely.

“…The estimated diagnostic molecular ratios of the selected PAHs for this study were presented in Table 4. From the selected ratios of Phe/Ant, BaP/BghiP, BaA/(BaA+Chr), Flt/(Flt+Pyr), BaP/(BaP+Chr), and Ind/(Ind+BghiP) the possible sources of PAHs identified are diesel combustion, gasoline, wood combustion, vehicle emission, coal combustion and traffic emissions (25,(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39). The observed ratios from this study ranged between 1.17-6.00, 0.09-1.14, 0.37-0.88, 0.44-0.87, 0.33-2.07, and 0.14-1.14, respectively, for Phe/Ant, BaP Based on the source identification observations, it can be concluded that mixed sources are the major contributors of PAHs to urban wastewater drains.…”

Wastewater from urban areas constitutes one of the major sources of pollutants contributed to aquatic ecosystem. This study was carried out to elucidate the occurrence and possible source of US Environmental Protection Agency identified 16 priority polycyclic aromatic hydrocarbons (PAHs) in water and sediments from the urban wastewater drains in Delhi, India. A total 60 samples (water and sediment) collected during year 2011-2012, and analyzed the following USEPA methods. Water and sediment samples were extracted using liquid-liquid and ultrasonication techniques, respectively. Glass column chromatography with activated silica was used for sample extracts clean-up, followed by quantification on HPLC equipped with diode array detector at 254 nm wavelength using mixture of acetonitrule and water as mobile phase. Concentrations of total 16 PAHs ( 16PAHs) in all drain water samples ranged from 0.29-35.22 μg/L (mean ± SD, 10.83 ± 10.66 μg/L), predominated by two-and three -ring PAHs. The 16PAHs concentrations in all collected sediments ranged between 220-19321 μg/kg (mean±SD, 5574 ± 6820 μg/kg) dry weights. High molecular weight PAHs (≥4-ring PAHs) were dominant in sediment samples. Benzo(a)pyrene equivalent (BaPeq), a relative carcinogenic potential to the corresponding PAHs to BaP was estimated and presented. A selected number of concentration ratios of specific PAHs compounds were calculated and used to diagnose the possible sources of PAHs contamination. The diagnostic ratios reflected pyrogenic input from gasoline or diesel powered vehicular emissions as the major source of PAHs. The levels of PAHs observed in water and sediments were compared with similar studies undertaken in other regions of the world.
