“…2 and Tables S6-S7). Similar concentrations have also been observed in the wastewaters of other WWTPs in China (Gao et al, 2012;Jia et al, 2012;Leung et al, 2012;Li and Zhang, 2010;Xu et al, 2007) and other countries (Golet et al, 2003;Karthikeyan and Meyer, 2006;Lindberg et al, 2005;Watkinson et al, 2007). However, ciprofloxacin was found at lower concentrations than those reported previously in other countries (Golet et al, 2002(Golet et al, , 2003Yang et al, 2005), or at the lower end of those concentration ranges in Hong Kong (Li and Zhang, 2010) and Sweden (Lindberg et al, 2005).…”

“…The normalized total mass load of the fluoroquinolones (including effluents and sludge) ranged from 181 to 392 μg/day/inhabitant, which is lower than those in Beijing in North China (789 μg/day/inhabitant) (Jia et al, 2012). Among the fluoroquinolones, the mass load per capita of norfloxacin (6.8-16.5 μg/day/inhabitant) and ofloxacin (8.91-32.6 μg/day/ inhabitant) in the effluents were at the lower range in Hong Kong (Leung et al, 2012) (norfloxacin: 12-1448 μg/day/inhabitant; ofloxacin: 77-3953 μg/day/inhabitant) and Beijing in North China (Gao et al, 2012) (ofloxacin: 62.5-480 μg/day/inhabitant). The normalized total mass load of macrolides ranged from 24.7 to 147 μg/day/inhabitant for effluents and ranged from 1.47 to 5.58 μg/day/inhabitant for sludge.…”

“…None of the four sulfonamides (SLM, SMI, SMT, and SMZ) were found in all soil samples. Generally, antibiotic compounds were not fully degraded in the WWTPs process; therefore antibiotic degradation products were formed and their concentrations were varied among WWTPs using different treatment processes (Gao et al, 2012a;Leung et al, 2012). In addition, none of the twenty four antibiotics were detected in the control soil samples.…”

“…However, the conventional biological processes in WWTPs could not remove the antibiotics and resistant bacteria completely, which could be influenced by compound-specific properties and treatment processes in specific WWTPs, such as hydraulic retention time (HRT) and solid retention time (SRT) (Rizzo et al, 2013;Lindberg et al, 2005;Li and Zhang, 2010). Numerous studies have reported the occurrence of antibiotics in wastewater, sludge, and the removal efficiency of antibiotics by WWTPs (Leung et al, 2012;Liu et al, 2012;. For example, Gao et al (2012a) investigated the occurrence of antibiotics in eight sewage treatment plants in Beijing, China, and found that the removal efficiency of antibiotics varied significantly among the eight WWTPs, with average removal efficiency of fluoroquinolones, sulfonamides, and macrolides ranging from 48% to 72%, 39% to 64%, and À34% to 69%, respectively.…”

a b s t r a c tThe abundance and distribution of antibiotics and antibiotic resistance genes (ARGs) in soils from six parks using reclaimed water in Beijing, China, were characterized. Three classes of commonly used antibiotics (tetracycles, quinolones, and sulfonamides) were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The highest concentrations of tetracyclines and quinolones were 145.2 mg kg À1 and 79.2 mg kg À1 , respectively. Detected tetG, tetW, sulI, and sulII genes were quantified by quantitative PCR. ARGs exhibited various abundances for different park soils. The integrase gene (intI1) as an indicator of horizontal gene transfer potential was also detected in high abundance, and had significant positive correlation with tetG, sulI, and sulII genes, suggesting that intI1 may be involved in ARGs dissemination. Both sulII and intI1 clones had high homology with some classes of pathogenic bacteria, such as Klebsiella oxytoca, Acinetobacter baumannii, Shigella flexneri, which could trigger potential public health concern.

“…Wastewater irrigation may be an important source of antibiotics in soil owing to their incomplete elimination by sewage treatments Leung et al 2012;Li and Zhang 2011;Wei et al 2011). Some antibiotics, such as NOR and OFL, have been detected in the secondary effluents, and even detected in the tertiary effluents with high concentrations Li et al 2013).…”

The recycling of reclaimed wastewater for irrigation and road cleaning is an important strategy to minimize water scarcity in megacities. However, little is known regarding the potential accumulation of antibiotics contained in reclaimed wastewater in urban soil. We investigated the occurrence and distribution of eight quinolones (QNs), nine sulfonamides (SAs), and five macrolides (MLs) antibiotics in urban surface soil in Beijing and Shanghai, China. QNs, especially norfloxacin (NOR), ofloxacin (OFL), and ciprofloxacin (CIP) were the predominant antibiotics in urban surface soil, and NOR revealed the highest average concentration of 94.6 μg kg −1 . The antibiotic concentrations in urban soil in our study were higher than those detected in agricultural soils after long-term wastewater irrigation and manure fertilization. The concentrations of antibiotics in Shanghai urban soil showed a significant negative correlation with soil pH and a positive correlation with total organic carbon (TOC), reflecting the effect of speciation and soil organic matter content on sorption and retention. In addition, antibiotic concentrations in the urban soil were positively correlated with heavy metal contents, likely due to their coexistence in reclaimed wastewater and the promoting effect of metals on the sorption of antibiotics. In several soil samples, NOR, OFL, CIP, enrofloxacin (ENR), and fleroxacin (FLE) showed higher concentrations than the trigger value of 100 μg kg −1 in soil, indicating a potential risk for the environment.
