“…Thus, biological transformation processes might be another possible pathway for the transformation from the PAHs to the OPAHs. Additionally, Haritash and Kaushik (2009) have demonstrated that the OPAHs could be formed and accumulated during the biological degradation process. The possible formation of OPAHs could be analyzed based on the ratios of OPAHs to the corresponding PAHs (Fig.…”

“…The three types of most commonly detected substituted polycyclic aromatic hydrocarbons (SPAHs) in the environment, including oxygenated-PAHs (OPAHs), nitrated-PAHs (NPAHs), and methyl-PAHs (MPAHs), could be emitted from the same sources as the PAHs, such as incomplete combustion, vehicle engines, and spilled oil (Nikolaou et al, 1984;Manoli et al, 2000;Bamford and Baker, 2003;Lundstedt et al, 2007;Tsapakis and Stephanou, 2007). In addition, the NPAHs and OPAHs may also be formed from the oxidation of PAHs by chemical and/or microbiological processes (Bamford and Baker, Science of the Total Environment 481 (2014) [178][179][180][181][182][183][184][185] 2003; Lundstedt et al, 2007;Wang et al, 2007;Haritash and Kaushik, 2009;Kojima et al, 2010). Generally speaking, NPAHs and OPAHs show higher toxicity than their parent PAHs, such as mutagenicity and carcinogenicity (Durant et al, 1996;Umbuzeiro et al, 2008).…”

• Methyl-PAHs, oxy-PAHs, and PAHs were detected in rivers, but no nitro-PAHs.• 2-MN, 9-FL, and AQ were the three highest-concentration SPAHs.• OPAHs were possibly transformed from the PAHs especially at higher temperature.• Wastewater treatment plant effluent was the major source for the SPAHs and PAHs.• The major amount of SPAHs and PAHs entered the farmland through irrigation. a b s t r a c t a r t i c l e i n f o Substituted polycyclic aromatic hydrocarbons (SPAHs) occur ubiquitously in the whole global environment as a result of their persistence and widely-spread sources. Some SPAHs show higher toxicities and levels than the corresponding PAHs. Three types of most frequently existing SPAHs, oxygenated-PAHs (OPAHs), nitrated-PAHs (NPAHs), and methyl-PAHs (MPAHs), as well as the 16 priority PAHs were investigated in this study. The purpose was to identify the occurrence, possible transformation, and source and fate of these target compounds in a water shortage area of North China. We took a river system in the water-shortage area in China, the Haihe River System (HRS), as a typical case. The rivers are used for irrigating the farmland in the North of China, which probably introduce these pollutants to the farmland of this area. The MPAHs (0.02-0.40 μg/L in dissolved phase; 0.32-16.54 μg/g in particulate phase), OPAHs (0.06-0.19 μg/L; 0.41-17.98 μg/g), and PAHs (0.16-1.20 μg/L; 1.56-79.38 μg/g) were found in the water samples, but no NPAHs were detected. The concentrations of OPAHs were higher than that of the corresponding PAHs. Seasonal comparison results indicated that the OPAHs, such as anthraquinone and 2-methylanthraquinone, were possibly transformed from the PAHs, particularly at higher temperature. Wastewater treatment plant (WWTP) effluent was deemed to be the major source for the MPAHs (contributing 62.3% and 87.6% to the receiving river in the two seasons), PAHs (68.5% and 89.4%), and especially OPAHs (80.3% and 93.2%) in the rivers. Additionally, the majority of MPAHs (12.4 kg, 80.0% of the total input), OPAHs (16.2 kg, 83.5%), and PAHs (65.9 kg, 93.3%) in the studied months entered the farmland through irrigation.

“…This study focused on Polycyclic Aromatic Hydrocarbons (PAHs), a class of widely distributed hazardous organic chemicals with a long-term persistence in ecosystems (Nascimbene et al, 2014). PAHs also have detrimental biological effects such as mutagenicity and carcinogenicity (Gan et al, 2009;Haritash and Kaushik, 2009;Camacho et al, 2012). Therefore, we investigated the change in the red edge using phenanthrene as the pollutant, evaluating changes of red edge slope and area as indictors of vegetation stress and exploring the mechanism of spectral changes.…”

a b s t r a c tTo investigate the mechanisms and potential for the remote sensing of phenanthrene-induced vegetation stress, we measured field canopy spectra, and associated plant and soil parameters in the field controlled experiment in the Yellow River Delta of China. Two widely distributed plant communities, separately dominated by reed (Phragmites australis) and glaucous seepweed (Suaeda salsa), were treated with different doses of phenanthrene. The canopy spectral changes of plant community resulted from the decreases of biomass and foliar projective coverage, while leaf photosynthetic pigment concentrations showed no significance difference among treatments. The spectral response to phenanthrene included a flattened red edge, with decreased first derivative of reflectance. The red edge slope and area consistently responded to phenanthrene, showing a strong relationship with aboveground biomass, coverage and canopy pigments density. These results suggest the potential of remote sensing and the importance of field validation to correctly interpret the causes of the spectral changes.

“…BTEX-benzene, toluene, ethyl-benzene, xylenes), VPHs and PAHs (Philp and Atlas 2005;Pavelescu et al 2008). Among the aforementioned chemicals the removal of genotoxic BTEX and PAH compounds from the environment is of the greatest importance (Haritash and Kaushik 2009;Gonul and Kucuksezgin 2012). Bioremediation is the only sustainable way to achieve their elimination.…”

Nowadays, because of substantial use of petroleum-derived fuels the number and extension of hydrocarbon polluted terrestrial ecosystems is in growth worldwide. In remediation of aforementioned sites bioremediation still tends to be an innovative, environmentally attractive technology. Although huge amount of information is available concerning the hydrocarbon degradation potential of cultivable hydrocarbonoclastic bacteria little is known about the in situ long-term effects of petroleum derived compounds on the structure of soil microbiota. Therefore, in this study our aim was to determine the longterm impact of total petroleum hydrocarbons (TPHs), volatile petroleum hydrocarbons (VPHs), total alkyl benzenes (TABs) as well as of polycyclic aromatic hydrocarbons (PAHs) on the structure of bacterial communities of four different contaminated soil samples. Our results indicated that a very high amount of TPH affected positively the diversity of hydrocarbonoclastic bacteria. This finding was supported by the occurrence of representatives of the a-, b-, c-Proteobacteria, Actinobacteria, Flavobacteriia and Bacilli classes. High concentration of VPHs and TABs contributed to the predominance of actinobacterial isolates. In PAH impacted samples the concentration of PAHs negatively correlated with the diversity of bacterial species. Heavily PAH polluted soil samples were mainly inhabited by the representatives of the b-, cProteobacteria (overwhelming dominance of Pseudomonas sp.) and Actinobacteria.
