“…In the Hai River system in northern China, the RQs of norfloxacpin and lomefloxacin ranged from 0.007 to 0.11 (Chen et al 2018). Similar results were also observed in the rivers located in central China; for example, the RQ of 13 antibiotics belonging to sulfonamides, tetracyclines, and fluoroquinolones detected in the Han River were demonstrated to have a value below 1, regardless of the concentration variation in seasons (Hu et al 2018). In addition to urban surface-water systems, a limited number of studies have Integr Environ Assess Manag 2020:43-52 © 2019 SETAC DOI: 10.1002/ieam.4204 attempted to measure the presence and assess the risks of antibiotics in rural areas, but the findings in the rural area were comparable to the present study concentrating on urban surface-water systems.…”

The occurrence of antibiotics in China's surface waters is an emerging concern. Although the ecological risk assessment for a small number of antibiotics is available in some regions, no attempt has been made to assess their risks at a national scale. The present work therefore proposed a probabilistic approach to characterize the ecological risks of 26 major use antibiotics, including sulfonamides, tetracyclines, beta‐lactams, fluoroquinolones, and macrolides, in China's surface waters. Initially we performed exposure and hazard assessment for these substances by synthesizing and interpreting the available occurrence and ecotoxicity data. For 22 antibiotics with sufficient ecotoxicity data, we assessed their risks by constructing joint probability curves (JPCs), from which their expected ecological risk (EER) estimates were less than 1%; for all the 26 antibiotics, in conjunction with the exposure distribution curves (EDCs), an assessment factor (AF) approach was applied and the potential risks were only detected for amoxicillin, ciprofloxacin, and penicillin with risk quotients (RQs) of 1.04, 1.54, and 5.83, respectively. These results indicated that the ecological risks of most major use antibiotics posed to nontarget organisms in China's aquatic environment seem to be low. Nevertheless, there are large uncertainties in the risk characterization processes, likely because of the significant data gaps in the understanding of exposure and hazards of these antibiotics.

“…Their results showed that the hazard quotients of antibiotics were higher in the sediment than those in the water body of the Hanjiang River. Moreover, antibiotic mixtures posed higher ecological risks to water resource in central China than aquatic organisms [32].…”

As a developing country with insufficient water resources, China’s water environment management and performance evaluation have important research value. The three provinces (Henan, Hubei, and Hunan) in central China with typical significance in geographical location and water resources governance were selected as research objects in this paper. Based on the principal component analysis (PCA) method and the pressure-state-response (PSR) model, a comprehensive evaluation system for the water environment in those three provinces during 2011–2017 was established in this paper. The evaluation results show that: (1) The water environment management and performance evaluation of the three provinces in central China were generally poor in 2011–2012, but the overall trend was rising; (2) in 2013–2014, the situation was improved compared to the previous two years, but needed further enhancement; (3) in 2015–2017, the water environment management and performance of the three provinces showed significant improvement. Among them, the Hubei Province had the highest water environment evaluation value (1.692), and the Henan Province had the most significant progress (from 0.043 to 1.671). The contributions of this paper are: (1) The comprehensive evaluation model based on PCA and the PSR model was constructed to analyze the sustainable development of water environment in central China; (2) the performance evaluation system for water environment management, which could comprehensively evaluate the performance of water environment treatment and effectively reveal the correlation between various indicators, was established. The principal factors in water environment management can be obtained by this evaluation system. Based on the analysis of the reasons underlying the above changes, the corresponding policy recommendations for improving water environment management and performance in central China were suggested in order to provide a reference for further improvement of water environment management in developing countries.

“…3 In addition, SDZ was found to be the most abundant contaminant in some waterways and sediments. 4 MFCs were developed as biological processing technology, and belong to the biological electrochemical system. 5 They can use various organic substrates (small molecules such as sugar, fatty acid, protein) to generate electricity through the biological oxidation process.…”

Overuse of antibiotics impacts environmental health worldwide. In this paper, the effect on the performance of microbial fuel cells (MFCs) under treatments with sulfonamides (SAs) was investigated. The results showed that when MCFs were treated with sulfamonomethoxine (SMM), the maximum power density was higher (20.95 mW/m 2) than when treated with sulfadiazine (SDZ) (19.79 mW/m 2). The power density of MFCs gradually decreased with increased concentration of SAs. Microbial activity analysis showed that SAs had negative effects on bacterial growth, riboflavin secretion and cell attachment on the MFCs anode. The power density of MFCs at different pH values was in order as follows: pH 6 > pH 7 > pH 8 > pH 5 > pH 9, where the highest was 22.90 mW/m 2 at pH 6. Electrochemical analysis showed that conditions favorable to the protonation of SMM also had a positive effect on the electrical performance of MFCs. These findings could provide the basis for uncovering the mechanism by which SAs affect electricity generation in MFCs, and demonstrates the feasibility for the efficient degradation of SAs and power generation.
