“…As the treatment process went on, from sampling site a (influent) to d (aerobic unit), the values of AQ/ Ant increased during the both seasons. Previous studies demonstrated that Ant could be biologically transformed to AQ (Cañ as et al, 2007;Lundstedt et al, 2007;Wu et al, 2010). So the result of the present study suggested that the biotransformation from Ant to AQ might occur along the process.…”

“…Solar radiation might be a factor influencing the transformation (Fan et al, 1996), which could explain the higher concentrations of OPAHs in the non-heating season. Wu et al (2010) proved that Ant and BaA could be transformed to AQ and BA-7,12-D and other metabolites by fungi in PAH-contaminated sediment. In the WWTPs, secondary treatment technologies are all activated sludge processes; fungi are prevalent species in the activated sludge, though they are not the dominant ones.…”

• 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.

“…Similar to other low molecular weight (LMW) PAHs such as naphthalene and phenanthrene, anthracene can be degraded by a wide variety of microorganisms. Isolated bacteria capable of anthracene metabolism include organisms from both Gram-positive (Dean-Ross et al, 2001;Khan et al, 2002;Zeinali et al, 2007;Zhang et al, 2009;Zeng et al, 2010;Ling et al, 2011) and Gram-negative genera (Story et al, 2004;Jacques et al, 2005;Baboshin et al, 2008;Arulazhagan and Vasudevan, 2011;Jin et al, 2012), and several fungi have been described that are capable of transforming anthracene (Wu et al, 2010;Acevedo et al, 2011). However, only recently have culture-independent methods been applied to directly link uncultivated or uncharacterized bacteria to the metabolism of anthracene in contaminated environments.…”

Stable-isotope probing was previously used to identify bacterial anthracene-degraders in untreated soil from a former manufactured gas plant site. However, subsequent pyrosequence analyses of total bacterial communities and quantification of 16S rRNA genes indicated that relative abundances of the predominant anthracene-degrading bacteria (designated Anthracene Group 1) diminished as a result of biological treatment conditions in lab-scale, aerobic bioreactors. This study identified Alphaproteobacterial anthracene-degrading bacteria in bioreactor-treated soil which were dissimilar to those previously identified. The largest group of sequences was from the Alterythrobacter genus while other groups of sequences were associated with bacteria within the order Rhizobiales and the genus Bradyrhizobium. Conditions in the bioreactor enriched for organisms capable of degrading anthracene which were not the same as those identified as dominant degraders in the untreated soil. Further, these data suggest that identification of polycyclic aromatic hydrocarbon-degrading bacteria in contaminated but untreated soil may be a poor indicator of the most active degraders during biological treatment.
