Determination of antibiotics in sewage from hospitals, nursery and slaughter house, wastewater treatment plant and source water in Chongqing region of Three Gorge Reservoir in China

Occurrence, distribution and potential affecting factors of antibiotics in sewage sludge of wastewater treatment plants in China

“…ROX, ERY and SPI were frequently detected in sludge samples with the mean concentration of 69.6, 10.4 μg/kg, and 3.64 μg/kg, respectively. This may be attributed to their high consumption in China (Chang et al, 2010). As for the other two macrolides, TYL and JOS, showed very rare detection and low concentration in sludge samples.…”

“…This may be due to the fact that sulfonamides appeared to have little sorption affinities to sludge, as was evidenced by their low values of Kds (Okuda et al, 2009). In addition, sulfonamides are primarily used for animals (Chang et al, 2010;Malintan and Mohd, 2006), and only a small percentage of them are used for human medicine. Therefore, the concentrations of sulfonamides in sludge were much lower than those of quinolones and macrolides.…”

Occurrence and ecological hazard assessment of selected antibiotics in the surface waters in and around Lake Honghu, China

“…Due to their continuous input into the environment through numerous pollution sources and their degradation-resistant characteristics, antibiotics are regarded as a class of ubiquitous and "pseudo-persistent" contaminants in aquatic environments (Nödler et al, 2012;Yao et al, 2015). Numerous studies have reported the concentrations of antibiotics ranged from several ng per liter to hundreds of μg per liter in various environmental compartments, such as hospital sewage, municipal sewage, surface waters, groundwater, and seawater (Brown et al, 2006;Kümmerer, 2009;Chang et al, 2010;Rodriguez-Mozaz et al, 2015;Yao et al, 2015Yao et al, , 2017Chen et al, 2015a, b;Ngumba et al, 2016;Sui et al, 2017). The antibiotic burden in water can result in direct toxicity to animals (Wollenberger et al, 2000;Wang et al, 2014;Yan et al, 2016) and plants (Migliore et al, 2003;Pan and Chu, 2016), but more importantly, they can induce antibiotic-resistant bacteria or genes, which increase health and ecological hazards through food chains, even at low concentrations (Wellington et al, 2013;Ye et al, 2016;Sharma et al, 2016).…”

Occurrence of pharmaceuticals and personal care products and associated environmental risks in the central and lower Yangtze river, China

“…Contaminations by heavy metals Yang et al, 2009), nutrients (Chen et al, 2000), pesticides , persistent organic pollutants Wang et al, 2009) and perfluorinated compounds (So et al, 2007) have been previously reported. However occurrence data for PPCPs in the Yangtze River basin has been limited to the Yangtze Estuary (Yan et al, 2013) and the Chongqing region of the Three Gorges Reservoir (Chang et al, 2010). Therefore, the aim of this study was to determine the occurrence of PPCPs in surface waters collected from the main water channel of the central and lower Yangtze River (from the Three Gorges Dam to the Yangtze River estuary), and from four large lakes within the river basin.…”
