“…These data suggest that human estrogens, rather than microconstituents like BPA, are the major contributors to estrogenic activity of raw wastewater and treated effluents. This observation is supported by other studies, which have observed changes in estrogenic activity during wastewater treatment using different in vitro assays (Drewes et al, 2005;Fernandez et al, 2007;Jacobsen et al, 2004;Jin et al, 2008;Körner et al, 2000Körner et al, , 2001Nakada et al, 2004;Sun et al, 2008;Tan et al, 2007;Tanaka et al, 2003;Vethaak et al, 2005).…”

“…Several recent studies have reported changes in both microconstituent concentrations and endocrine activity during wastewater treatment. Bioassays used by various researchers to assess endocrine activity in influent and effluent wastewaters included a variety of in vitro assays, including yeast estrogen screen (YES), E-screen assay, and a receptor mediated luciferase reporter gene assay Drewes et al, 2005;Hemming et al, 2004;Jin et al, 2008;Körner et al, 1999;Leusch et al, 2005Leusch et al, , 2006Murk et al, 2002;Rutishauser et al, 2004;Tanaka et al, 2003). Matsui et al (2000) used the YES assay to investigate differences in estrogenic activity between the influent and effluent at the WWTP in Lake Biwa, Japan.…”

The presence of microconstituents in effluents from municipal wastewater treatment plants (WWTPs) and their receiving waters has attracted considerable recent attention. This review summarizes the state of the science on the removal of bisphenol A (BPA) by WWTPs and presents evidence that the compound should be effectively removed in well-operated activated sludge systems. The biological treatment of BPA has been extensively studied in laboratory, pilot, and full-scale municipal WWTPs. Although removal efficiencies varied, the average of the reported removal efficiencies for BPA in full-scale facilities was 84%. Mass balance studies conducted in the laboratory with '"C-labeled BPA and studies of full-scale facilities show that biodégradation is the dominant removal process, consistent with the fact that BPA is readily degradable and able to support microbial growth. Many of the plants were able to reduce BPA concentrations in the wastewater effluent to significantly less than 1 |ig/L. This review examines operating parameters important for optimizing and sustaining the perfonnance of wastewater treatment systems including solids residence time (SRT), which proved to be the most critical. The weight of evidence suggests the optimum SRT needs to be approximately 10 days to ensure high treatment efficiencies. Other optimum operating conditions include maintaining dissolved oxygen concentrations of greater than or equal to 2.0 mg/L, elevating the SRT during periods of low temperature, and implementing step-feed control during storm-induced high flow conditions to avoid the washout of biomass.

“…Beyond total organic carbon content, the ability to predict partitioning of BPA to sediments is dependent on pH (Zeng et al 2006), black carbon (Zeng et al 2006), ionic strength (Zeng et al 2006; Xu et al 2008), and temperature (Xu et al 2008). Bisphenol A has a pKa of 10.29 ± 0.69 (Table 1), which results in enhanced sorption at lower pH values and higher solubility or desorption at pH values closer to the pKa.…”

Because bisphenol A (BPA) is a high production volume chemical, we examined over 500 peer-reviewed studies to understand its global distribution in effluent discharges, surface waters, sewage sludge, biosolids, sediments, soils, air, wildlife, and humans. Bisphenol A was largely reported from urban ecosystems in Asia, Europe, and North America; unfortunately, information was lacking from large geographic areas, megacities, and developing countries. When sufficient data were available, probabilistic hazard assessments were performed to understand global environmental quality concerns. Exceedances of Canadian Predicted No Effect Concentrations for aquatic life were >50% for effluents in Asia, Europe, and North America but as high as 80% for surface water reports from Asia. Similarly, maximum concentrations of BPA in sediments from Asia were higher than Europe. Concentrations of BPA in wildlife, mostly for fish, ranged from 0.2 to 13 000 ng/g. We observed 60% and 40% exceedences of median levels by the US Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey in Europe and Asia, respectively. These findings highlight the utility of coordinating global sensing of environmental contaminants efforts through integration of environmental monitoring and specimen banking to identify regions for implementation of more robust environmental assessment and management programs.

“…Effluents from domestic sewage treatment plants (STPs) have been identified as the major contributor of estrogens to aquatic environments [8]. These compounds, with the exception of EE2, have now been widely detected in Chinese STP effluents [9][10][11][12][13][14][15][16][17][18][19] and rivers [20]. This apparent absence of EE2 is similar to findings in Japan [8,21].…”

“…There were 43 separate datasets of influent and effluent concentrations found for Chinese STPs [9][10][11][12][13][14][15][16][17][18][19]. Thus, a per capita release of estrogens was derived from the measured influent and effluent concentrations.…”

All rights reservedAbstract: The GWAVA model, incorporating regional water abstractions and reservoir information, was used to model human-sourced steroid estrogens: estrone (E1) and estradiol (E2) in the Yellow River catchment. The river flows in the main stem were calibrated using gauged flows. Following a review of Chinese data on estrogen discharge from a range of sewage treatment plants, low, median and high discharge rates were identified and used as best, expected and worst case scenarios, respectively. For any given location, the time-variation of modelled estrogens levels was summarized using the mean and upper 90th percentile (90%ile), which is where the model predicts 90% of values would be below this concentration. The predicted means and 90%iles for E1 were comparable with previous E1 measurements reported in the river. For the whole catchment, only 19% (mean value) of the river system by length was predicted to exceed 1 ng/L E2 equivalents (EEQ) using expected estrogen sewage discharge. Only 3% of the network by length was predicted to exceed the dangerously high 10 ng/L EEQ when considering 90%ile concentrations. The highest exposures were in the Fen and Wei tributaries. Endocrine disruption risk from estrogens was predicted to be minimal in the main stem.Only in the worst case discharge scenario and 90%ile predicted concentrations, were the most downstream river reaches of the main stem predicted to be at risk. Reservoirs appeared to be helpful in reducing estrogen concentrations thanks to longer water residence facilitating biodegradation. This article is protected by copyright. All rights reserved
