Emerging contaminants such as 17α-ethynylestradiol (EE2) can be discharged from sewage systems and contaminate water supplies. Paranoá Lake is a strategic reservoir in Brasília (Brazil) that receives treated treatment plants (STPs) has recently become supply. This study monitored EE2 residues different matrices watershed using the ELISA method. monitoring was performed together with local envir...

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...

Abstract Micropollutants have been continuously detected in freshwater. In parallel, the potential adverse effects of human exposure to endocrine-disrupting chemicals (EDCs) through drinking water gaining attention researchers and health authorities. Given this fact, study aimed evaluate effectiveness chlorination photolysis remove estrogenic activity caused by mixtures EDCs water: estrone (E1:...

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...
