Occurrence and behavior of antibiotics in water and sediments from the Huangpu River, Shanghai, China

Occurrence, Seasonal Variation and Risk Assessment of Antibiotics in Qingcaosha Reservoir

“…Compared with previous studies (Table 1), the concentrations of SDZ and SQX are relatively higher than those in the Yangtze Estuary [22], Huangpu River [21], and Urban water [29]. The concentration of SMM (n.d-163.2 ng/L) in this study is lower than those in the Huangpu River (ranged from 2.05-623.27 ng/L) [32] and the Pearl River (ranged from n.d-1080 ng/L) [33].…”

“…Because of the strong sorption to sediments and high hydrophobicity of the MLs, the concentrations of the MLs in the aquatic environment were found to be very low. In previous investigations, TC and DC have also been detected in the Huangpu River [20] and Yangtze Estuary [21]. The detection frequencies of TCs in the Huangpu River were high; this might be due to the large usage and discharge in the river [20].…”

Occurrence and risk assessment of antibiotics in river water in Hong Kong

“…The concentrations of DO (n.d-82.2 ng/L) were found to be comparable to those in the Huangpu River (n.d-113.9 ng/L, Jiang et al, 2011;n.d-54.3 ng/L, Chen and Zhou, 2014), Chaohu in China (n.d-42.3 ng/L, Tang et al, 2015) and in stream water in North America (n.d-110 ng/L, Kolpin et al, 2002), but were higher than those in the Ebro River (2.5-65.2 ng/L, García-Galán et al, 2011), the Yangtze River (n.d-2.4 ng/L, Yan et al, 2013), and the Pearl River (0.19-13.69 ng/L, Yang et al, 2011). DO has a low degradation potential in the environment and is easily disposed of in soil or sediment (Kolpin et al, 2002;Andreozzi et al, 2003).…”

“…The levels of the sulfonamides detected were compared to the levels found in other countries. The concentration of SMZ in the river water (n.d-580.4 ng/L) was the same as in the Huangpu (2.1-623.3 ng/L, Jiang et al, 2011;19.9-389.4 ng/L, Chen and Zhou, 2014), urban surface waters of Beijing in China (n.d-123 ng/L, Li et al, 2015) and Pearl Rivers in China (n.d-1080 ng/L, Yang et al, 2011), and slightly higher than in the Yangtze Estuary in China (0.53-89.1 ng/L, Yan et al, 2013), the Ebro River in Spain (2.5-65.2 ng/L, García-Galán et al, 2011), and stream water in North America (n.d-120 ng/L, Kolpin et al, 2002). The concentrations of the other target sulfonamides, including SMX (n.d-3.1 ng/L), SD (n.d-14.8 ng/L), and SP (n.d-3.2 ng/L), were lower than in other river waters in China and in countries such as Beijing (China) , North America (Kolpin et al, 2002), Spain (García-Galán et al, 2011;Boleda et al, 2013;Mendoza et al, 2015), France (Tamtam et al, 2008), and Australia (Watkinson et al, 2009) (Table 2).…”

The Effects of Antibiotics on Microbial Community Composition in an Estuary Reservoir during Spring and Summer Seasons

“…Based on the results of our preliminary experiment within QCS Reservoir in an earlier stage, we referred to related researches about antibiotics in the Yangtze estuary [17][18][19], and antibiotics including the fluoroquinolones (FQs) (such as ofloxacin (OFX), ciprofloxacin (CFX), norfloxacin (NFX)), Sulfonamides (SAs) (such as sulfamonomethoxine (SMM), sulfadiazine (SDZ), sulfaquinoxaline (SQX)), Tetracyclines (TCs) (such as tetracycline (TC), doxycycline (DC)), β-lactams (such as penicillin G (ETM), penicillin V (PEN V), cefalexin (LEX)), Macrolides (MLs) (such as erythromycin-H 2 O (ETM), tylosin (TYL)) and other common antibiotics (such as Polymix-B (POL), Vancomycin (VAN), Lincomycin (LIN)) were selected as target compounds in our research. The antibiotic standards and internal standards (purities of all the chemicals are >98%) were purchased from Dr. Ehrenstorfer GmbH (Augsburg, Germany), and the detection methods of antibiotics were according to our colleague Yue Jiang's research, and the further information about preparation, extraction, sample detection and analysis can be found in the Supplementary Methods.…”
