“…However, this seasonal variation trend is inconsistent with previous investigations [31,39]. Furthermore, it was notable that the antibiotic compositions in the rivers did not exhibit a significant difference with the seasonal variation (analysis of similarities (ANOSIM), p > 0.05) (Supplementary Materials Figure S3), indicating that perennial anthropic activity, but not the seasons or hydrologic conditions, may be an important factor influencing the usage pattern of these antibiotics.…”

“…In comparison, the information found in the water samples of the reservoir system was inconsistent with those in the river system. Taken together, these differences in the detection frequencies and levels of various antibiotics in the river-reservoir system may be attributed to the usage patterns of antibiotics in the surrounding catchments, as well as to the biogeochemical processes of antibiotics along with different hydrologic gradients, such as photo-degradation, adsorption, and biodegradation [3,27,31]. For fluoroquinolones, the maximum concentration of CIP was found at site S3 (dry season) with the value of 442.1 ng/L, followed by site S5 (wet season) with the value of 417.6 ng/L (Supplementary Materials Figure S2).…”

Antibiotic pollutions in the aquatic environment have attracted widespread attention due to their ubiquitous distribution and antibacterial properties. The occurrence, distribution, and ecological risk assessment of 17 common antibiotics in this study were preformed in a vital drinking water source represented as a river-reservoir system in South China. In general, 15 antibiotics were detected at least once in the watershed, with the total concentrations of antibiotics in the water samples ranging from 193.6 to 863.3 ng/L and 115.1 to 278.2 µg/kg in the sediment samples. For the water samples, higher rain runoff may contribute to the levels of total concentration in the river system, while perennial anthropic activity associated with the usage pattern of antibiotics may be an important factor determining similar sources and release mechanisms of antibiotics in the riparian environment. Meanwhile, the reservoir system could act as a stable reactor to influence the level and composition of antibiotics exported from the river system. For the sediment samples, hydrological factor in the reservoir may influence the antibiotic distributions along with seasonal variation. Ecological risk assessment revealed that tetracycline and ciprofloxacin could pose high risks in the aquatic environment. Taken together, further investigations should be performed to elaborate the environmental behaviors of antibiotics in the river-reservoir system, especially in drinking water sources.

“…These high-intensive usages of antibiotics plus the relatively low sewage treatment rate may lead to a high contamination level in China in comparison with the other areas in the world . Thus, the antibiotic occurrence and ecological hazards evaluation in the surface waters in China has been of great concern (Jiang et al, 2011;Zhang et al, 2015;Deng et al, 2016;Xu et al, 2016;Yao et al, 2017;Ma et al, 2017;Chen et al, 2017). However, these studies mainly focused on rivers; moreover, the antibiotic information on lakes in China is still limited, even with Lake Taihu, Chaohu, and Baiyangdian having been studied (Cheng et al, 2014;Xu et al, 2014;Tang et al, 2015).…”

“…For the past decades, water pollution has got greater attentions due to the growing contaminants from traditional pollutants to emerging contaminants [1]. As one of the mostly emerging pollutants, the pharmaceuticals have attracted considerable attention due to the higher usage for both human health and livestock breeding [2]. Cimetidine (as showed in Table 1), a kind of typical pharmaceuticals, is widely used as H 2 -receptor antagonist in mammals for the treatment of duodenal ulcers and gastric hypersecretion [3,4].…”

In this study, to investigate the elimination of micropollutant from aqueous solutions by construction waste, waste red brick (WRB) with and without incorporated of iron species (goethite and hematite) were prepared by a simple method. The prepared materials were systematically characterized and batch experiments were conducted to study the elimination of typical micropollutant cimetidine from the water environment. Results showed that both two iron species could be successfully incorporated onto WRB and the main structure of WRB were maintained. The adsorption process of cimetidine onto bricks was fast due to the microstructure and useful adsorption sites on the surface of bricks. The Langmuir model fitted the experimental data better and the qmax of cimetidine increased about 24.4% and 39.6% for the incorporation of hematite and goethite, respectively. The pH values influenced the adsorption behavior greatly and the favorable pH value was around 6.0. The charge screening effect and competition adsorption may influence the adsorption behavior together. Due to the interaction between cimetidine and bricks, the outer-sphere complexation may be formed in the adsorption process. This study shows new methods for the elimination of the micropollutant from the water environment and offers useful guidelines for the reuse of construction waste.
