“…The concentrations varied across a range from sub ng/L concentrations to tens of ng/L, which were generally comparable to the reported levels from other published references concerned with DWSs of The Netherlands (de Jongh et al, 2012), United States (Loraine and Pettigrove, 2005;Stackelberg et al, 2007;Focazio et al, 2008;Benotti et al, 2009;Wang et al, 2011;Padhye et al, 2014), Canada (Kleywegt et al, 2011), France (Vulliet et al, 2011;Mompelat et al, 2011), Spain (Boleda et al, 2011;Huerta-Fontela et al, 2011) and South Korea (Kim et al, 2007). The concentration levels in this survey were similar to reports on those in the DWSs of the Chongqing area of China (Chang et al, 2010;Yan et al, 2014).…”

“…Several mechanisms had been proposed to explain seasonal variations in pharmaceuticals, including seasonal discharges, water temperature, irradiance and dilution effects (Daneshvar et al, 2010;Padhye et al, 2014). The lower temperatures presented during cold seasons result in slower rates of biodegradation than during the warm season.…”

a b s t r a c tPharmaceuticals in drinking water sources (DWSs) have raised significant concerns for their persistent input and potential human health risks. Currently, little is known about the occurrence of pharmaceuticals in DWSs in China. In this study, a survey for multi-class pharmaceuticals in DWSs of five major river watersheds in China was conducted from 2012 to 2013. Samples were collected from 25 sampling sites in rivers and reservoirs. 135 pharmaceuticals were analyzed using solid-phase extraction and ultra-performance liquid chromatography tandem mass spectrometry. The results showed that a total of 70 pharmaceuticals were present in the samples, and the most frequently detected ones included sulfonamides, macrolides, antiepileptic drugs, anti-inflammatory drugs, and β-blockers, etc. Amongst these, maximum concentrations of lincomycin, sulfamethoxazole, acetaminophen and paraxanthine were between 44 ng/L and 134 ng/L, and those of metoprolol, diphenhydramine, venlafaxine, nalidixic acid and androstenedione were less than 1 ng/L. Concentrations of the two that were most persistent, DEET and carbamazepine, were 0.8-10.2 ng/L and 0.01-3.5 ng/L, respectively. Higher concentrations of cotinine were observed in warm season than in cold season, while concentrations of lincomycin were the opposite. In a causality analysis, the occurrence of pharmaceuticals in DWSs depends mainly on the detection limits of the methods, their usage and the persistence in the aquatic environment.

“…However, there still exist a variety of trace organic pollutants and pathogenic microorganisms that pose potential risk in its direct reuse [2,3]. Endocrine-disrupting chemicals (EDCs) have been widely detected in secondary effluent [4]. They pose a threat to ecological security and human health by interfering with endocrine system even at concentrations as low as ng·L −1 level [5].…”

Endocrine-disrupting chemicals (EDCs) in the secondary effluent discharged from wastewater treatment plants are of great concern when water reuse is intended. The combined process of ozone (O 3 ) and ultrafiltration (UF) is a promising EDC removal method. The removal efficiency of five EDCs using O 3 , UF and their combination were investigated and compared. The five EDCs were estrone, 17β-estradiol, estriol, 17α-ethynyl estradiol and bisphenol A, which are typically present in secondary effluent. Results showed that organic matters in secondary effluent became easier to be removed by the combined process, with ultraviolet absorbance reduction enhanced by 11%-18% or 24%-26% compared to the UF or O 3 alone. The removal efficiency of EDC concentration, estrogenicity and acute ecotoxicity by the combined process was 17%-29% or 54%-92%, 19% or 73%, 40% or 60% greater, respectively, than that of the O 3 or UF alone. Particularly, when EDCs were treated by the combination of O 3 and UF, about 100% EDC removal efficiency was achieved. Overall, the combined application of O 3 and UF offers an effective approach to control the concentration and toxicity of EDCs in secondary effluent.

“…NOMs lead to disinfection byproduct (DBPs) by reacting with common disinfectants (e.g., chlorine, ozone, chlorine dioxide, chloramines) [1]. Certain SOCs, encompassing pharmaceuticals and personal care products (PPCPs), pesticides, household chemicals and endocrine disrupting chemicals, have been shown to impose adverse impacts on human, wildlife and aquatic ecosystems [2,3]. Organic contaminants have become an increasing cause of concern for governments and water authorities around the world as they attempt to implement sustainable water treatment practices.…”
