“…This is consistent with the general water quality classification of the three rivers. The estrogenic activities detected in surface water and sediment of the Shijing River were approximately one to two orders of magnitude higher than those reported in Korea [32], Portugal [33], the United Kingdom [34], and the United States [35], where the estrogenic activities ranged from below the limit of detection to 4.01 ng EEQ/L in surface water and from below the limit of detection to 12.1 ng EEQ/g in sediment. The estrogenic activities in the rivers of other regions clearly fall in the range for the Liuxi and Zhujiang rivers.…”

Abstract-This paper reports screening of multiple hormonal activities (estrogenic and androgenic activities, antiestrogenic and antiandrogenic activities) for surface water and sediment from the Pearl River system (Liuxi, Zhujiang, and Shijing rivers) in South China, using in vitro recombinant yeast bioassays. The detection frequencies for estrogenic and antiandrogenic activities were both 100% in surface water and 81 and 93% in sediment, respectively. The levels of estrogenic activity were 0.23 to 324 ng 17b-estradiol equivalent concentration (EEQ)/L in surface water and 0 to 101 ng EEQ/g in sediment. Antiandrogenic activities were in the range of 20.4 to 935 Â 10 3 ng flutamide equivalent concentration (FEQ)/L in surface water and 0 to 154 Â 10 3 ng FEQ/g in sediment. Moreover, estrogenic activity and antiandrogenic activity in sediment showed good correlation (R 2 ¼ 0.7187), suggesting that the agonists of estrogen receptor and the antagonists of androgen receptor co-occurred in sediment. The detection frequencies for androgenic and antiestrogenic activities were 41 and 29% in surface water and 61 and 4% in sediment, respectively. The levels of androgenic activities were 0 to 45.4 ng dihydrotestosterone equivalent concentration (DEQ)/L in surface water, and the potency was very weak in the only detected sediment site. The levels of antiestrogenic activity were 0 to 1,296 Â 10 3 ng tamoxifen equivalent concentration (TEQ)/L in surface water and 0 to 89.5 Â 10 3 ng TEQ/g in sediment. The Shijing River displayed higher levels of hormonal activities than the Zhujiang and Liuxi rivers, indicating that the Shijing River had been suffering from heavy contamination with endocrine-disrupting chemicals. The equivalent concentrations of hormonal activities in some sites were greater than the lowest-observed-effect concentrations reported in the literature, suggesting potential adverse effects on aquatic organisms.

“…These values are comparable to YES E2 EQs reported by other studies, including sediments collected from the UK rivers with 0.20-13 ng E2 EQ g −1 dw (Thomas et al 2004) and German rivers with 0.03-1.3 ng E2 EQ g −1 dw (Grund et al 2011), as well as the values of sediment analysis from Dutch inland and estuarine waters ranging from 0.10 to 1.2 ng E2 EQ g −1 dw (Legler et al 2002) and from Chinese Liao River with non-detectable to 6.04 ng E2 EQ g −1 dw ). On the other hand, sediment YES-E2 EQs reported in our present study are much greater than those reported in other studies, including sediments from the UK estuaries with 0.021-0.03 ng E2 EQ g −1 SEQ (Peck et al 2004), from Dutch inland and estuarine waters with 0.005 and 0.34 ng E2 EQ g −1 SEQ (Houtman et al 2006), and sediment from a Korean lake with E2 EQs ranging from 0.003 to 0.064 ng E2 EQ g −1 dw (Koh and Khim 2005).…”

“…It is hypothesized that this distribution may relate with a sedimentation effect in the reservoir. Surface sediments are frequently a sink for persistent organic pollutants and EDCs in riverine environments (Ahlf et al 2002;Forstner and Westrich 2005;Labadie et al 2007;Vigano et al 2006;Peck et al 2004;Wang et al 2011).

Two types of biological tests were employed for monitoring the toxicological profile of sediment cores in the Three Gorges Reservoir (TGR), China. In the present study, sediments collected in June 2010 from TGR were analyzed for estrogen receptor (ER)-and aryl hydrocarbon receptor (AhR)-mediated activities. The estrogenic activity was assessed using a rapid yeast estrogen bioassay, based on the expression of a green fluorescent reporter protein. Weak anti-estrogenic activity was detected in sediments from an area close to the dam of the reservoir, and weak estrogenic activities ranging from 0.3 to 1 ng 17β-estradiol (E2) equivalents (EQ) g −1 dry weight sediment (dw) were detected in sediments from the Wanzhou to Guojiaba areas. In the upstream areas Wanzhou and Wushan, sediments demonstrated additive effects in coadministration of 1 nM E2 in the yeast test system, while sediments from the downstream Badong and Guojiaba areas showed estrogenic activities which seemed to be more than additive (synergistic activity). There was an increasing tendency in estrogenic activity from upstream of TGR to downstream, while this tendency terminated and converted into anti-estrogenic activity in the area close to the dam. The AhR activity was detected employing rat hepatoma cell line (H4IIE). EROD activities were found homogenously distributed in sediments in TGR ranging from 200 to 311 pg 2,3,7,8-tetrachlorodibenzo-p -dioxin (TCDD) EQ g −1 dw for total AhR agonists and from 45 to 76 pg TCDD EQ g −1 dw for more persistent AhR agonists. The known AhR agonists polycyclic aromatic hydrocarbon, polychlorinated biphenyl, and PCDD/F only explained up to 8 % of the more persistent AhR agonist activity in the samples, which suggests that unidentified AhR-active compounds represented a great proportion of the TCDD EQ in sediments from TGR. These findings of estrogenic potential and dioxin-like activity in TGR sediments provide possible weight-of-evidence of potential ecotoxicological causes for the declines in fish populations which have been observed during the past decades in TGR.

An increasing part of drinking water in Europe is prepared from surface water. At the same time, a growing number of emerging contaminants is being discovered in surface water. This review provides an overview of classes of emerging contaminants nowadays detected in the aquatic environment that are of relevance for drinking water production. These comprise e.g. endocrine disrupting compounds, such as hormones and compounds with hormone-like properties, pharmaceuticals, illicit and non-controlled drugs, sweeteners, personal care products, complexing agents, nanoparticles, perfluorinated compounds, flame retardants, pesticides, and fuel additives. The individual compounds are observed in concentrations that are generally considered too low to cause acute effects. Nevertheless, health effects due to long-term exposure to a mixture of low concentrations of all kinds of emerging contaminants cannot be excluded with current knowledge. Moreover, contamination of drinking water with man-made substances is considered unwanted in principle. The precautionary principle is used to motivate that prevention of emission of emerging contaminants into the environment is the preferred approach to safeguard sustainable drinking water production. In the mean time, extensive monitoring of the sources and development and application of advanced treatment techniques are used to prepare safe drinking water.
