Abstract This study employs a novel combined pilot plant consisting of an anaerobic reactor followed by membrane electrochemical bioreactor (eMBR) to treat domestic water containing selected contaminants emerging concern (CECs) [ibuprofen (IB), carbamazepine (CBZ), diclofenac (DCF) and 17α-ethinylestradiol (EE2)]. The first phase operated as conventional achieve the removal organic matter [chem...

Abstract The relationship between the distribution of medicines used in Pandemic by SARS-COV-19 municipality Rio de Janeiro and estimated level environmental risk caused their residues was evaluated. amount distributed primary health care (PHC) units 2019 2021 were collected. quotient (RQ) corresponded to ratio predictive concentration (PECest) obtained consumption excretion each drug its non-e...

The effect of impedance measurements applied voltage on the detection 17α-ethinylestradiol (EE2) in water samples using interdigitated electrodes (IDE) coated or not with thin films, is described. Firstly, immersion EE2 aqueous solutions layer-by-layer films prepared poly(allylamine hydrochloride) (PAH), graphene oxide (GO), poly(1-(4-(3-carboxy-4-hydroxyphenylazo) benzene sulfonamido) 1,2 etha...

The fish Vitellogenin (Vg) gene has been applied as a biomarker for exposure to estrogenic compounds in the aquatic environment. In this study, we cloned and characterized Vg cDNA from the Korean rose bitterling Rhodeus uyekii (Ru-Vg). The Ru-Vg cDNA encodes a 1424-amino-acid polypeptide that belongs to the VgAo1 family and contains a putative signal peptide, lipovitellin I, phosvitin, and lipo...

This study analyses the electrokinetic (EK) contribution to removal from a clay soil of mixture 10 different contaminants emerging concern (CECs; 17?-estradiol, E2; sulfamethoxazole, SMX; bisphenol A, BPA; ibuprofen, IBU; 17?-ethinylestradiol, EE2; oxybenzone, OXY; diclofenac, DCF; triclosan, TCS; caffeine, CAF; carbamazepine, CBZ). After 4 days, CECs natural attenuation was between 0% (CBZ) an...

Sewage treatment systems can prevent the direct discharge of endocrine disruptors, such as 17α-ethinylestradiol (EE2), into environment. Treatment capable promoting total phosphorus (TP) removal, sequencing batch reactors (SBRs), are promising in this regard. Two lab-scale SBRs with different sludge retention times (SRTs) were assessed for their EE2 and TP removal rates. Anaerobic/aerobic/anoxi...

This study describes the application of Ag/Nb2O5 catalysts, suspension and spheres alginate immobilized for degradation 17α-Ethinylestradiol (EE2). The techniques used to characterize photocatalysts were as follows: X-ray diffraction (XRD), N2 adsorption–desorption analysis (BET), point charge zero (PZC), scanning electron microscopy (SEM) energy dispersive spectroscopy (EDS). Different catalys...

To contribute to the development and evaluation of a practical and cost-effective in vivo testing system for endocrine disruption (specifically environmental estrogens), the effects of 17alpha-ethinylestradiol (EE2) were assessed in a gonadal recrudescence assay with the fathead minnow (Pimephales promelas). Mature male and female fathead minnows were kept first at 15 degrees C on a 8 h light/1...

Rhodococcus equi ATCC13557 was selected as a model organism to study oestrogen degradation based on its previous ability degrade 17α-ethinylestradiol (EE2). Biodegradation experiments revealed that R. unable metabolise EE2. However, it able E2 with the major metabolite being E1 no further of E1. conversion into incomplete, 11.2 and 50.6% degraded in mixed (E1-E2-EE2) E2-only conditions, respect...
