Fate of typical endocrine active compounds in full-scale wastewater treatment plants: Distribution, removal efficiency and potential risks

Occurrence and removal of four artificial sweeteners in wastewater treatment plants of China

“…33 The negative removal efficiency may be caused by the release of artificial sweeteners in the mud phase to the aqueous phase and the conversion of intermediate metabolites. 34 Subedi and Kannan 2 also found the negative removal efficiency (−54.2%) of ACE in the WWTP of Albany Area, New York, U. S. A., and the research results of Li et al 3 showed that the lowest removal efficiency of SUC was nearly −100% in a WWTP of Australia. Among the four artificial sweeteners, the median removal of ACE, APM and NTM was more than 50%, while SUC had a much lower median removal efficiency of 34.6%.…”

Detection and Treatment of Persistent Pollutants in Water: General Review of Pharmaceutical Products

“…Improved results are obtained with several advanced oxidation processes. [112] The rate of elimination of pharmaceuticals depends on the microbial populations capability to degrading the main contaminant as well as the by-products generated during biotransformation (metabolic and co-metabolic pathway), the initial concentration of the PP and the overall treatment system's environment. [97] On the other hand, the continuous exposure of microbial consortia in water allows them to acclimatize, enriching the biodegradation activity and sometimes favoring the persistence of contaminants.…”

“…According to the literature review and to what is summarized in Table 6, it has been found that antidepressant pharmaceuticals are not easily biodegraded. Improved results are obtained with several advanced oxidation processes [112] . The rate of elimination of pharmaceuticals depends on the microbial populations capability to degrading the main contaminant as well as the by‐products generated during biotransformation (metabolic and co‐metabolic pathway), the initial concentration of the PP and the overall treatment system's environment [97] …”

Ecotoxicological assessment of the effects of fluoxetine on Daphnia magna based on acute toxicity, multigenerational reproduction effects, and attraction-repellence responses

“…In fact, fluoxetine has been detected in untreated wastewaters and effluents of wastewater treatment plants (WWTP) at concentrations that vary between 0.012 and 3.5 μg/L (Brooks et al, 2003;Schultz et al, 2010;Writer et al, 2013;Ribeiro et al, 2014). Fluoxetine cannot be eliminated completely by WWTPs as shown by Yuan et al (2013) and Cao et al (2020). In fact, Ma et al (2018) reported that the effluents of WWTPs had an even higher concentration; up to 300%.…”
