A review toward contaminants of emerging concern in Brazil: Occurrence, impact and their degradation by advanced oxidation process in aquatic matrices

Ultrahigh surface area of single-atom iron nanosheets assists in the efficient utilization of reactive oxygen species in the peroxymonosulfate activation process for pollutant removal

“…To verify the practicality of the SAFe/CNS catalyst, the catalytic activity of SAFe/CNS in activating PMS for BPA degradation in a complex water matrix was investigated. According to previous studies, the concentration of BPA in surface water is generally at the ng L −1 level, 48,49 and as far as we know, the reported maximum concentration of BPA in surface water is 39.9 μg L −1 , 50 while BPA concentrations detected in the influent water of wastewater treatment plants (WWTPs) ranged from ng L −1 to mg L −1 . 51 Therefore, to closely reflect the degradation process in the real environment, we chose an initial BPA concentration of 0.1 mg L −1 in the practicality investigation.…”

An Overview of the Impact of Pharmaceuticals on Aquatic Microbial Communities

“…Among the biological processes, it is possible to enumerate the following as examples: activated sludge [ 130 ], microalgae treatment [ 131 ], biofiltration [ 132 ], and constructed wetlands [ 133 ]. Photoreaction can also be used to eliminate some pharmaceuticals, as reviewed by Abd Rahman, Choong [ 134 ], as well as filtration/adsorption processes [ 135 , 136 ] and advanced oxidation processes [ 137 ]. In this review, these strategies will not be discussed in detail since it is possible to find a vast number of recent review articles describing different strategies to remove pharmaceuticals and ECs in general [ 131 , 132 , 133 , 134 , 135 , 136 , 137 ].…”

Challenges on solar oxidation as post-treatment of municipal wastewater from UASB systems: Treatment efficiency, disinfection and toxicity

“…RQ calculated for drug mixtures and their metabolites indicates high risk to aquatic organisms ( Green algae , Daphnid and Fish ). As direct discharge of hospital wastewater to municipal wastewater network or to surface waters are frequent practices in developing countries due lack of sanitation infrastructure ( Azuma et al, 2019 ), results obtained in this risk assessment are very concerning ( Marson et al, 2022 ), especially with regard to drugs and their metabolites.…”

“…Among CECs, pharmaceuticals have been associated to ecotoxicological risks ( Sodré et al, 2018 ) and adverse effects upon aquatic organisms, depending on exposure route, bioavailability, susceptibility, and stability ( Espinosa-Barrera et al, 2021 ). Marson et al (2022) concluded that from the high load of CECs present in municipal wastewater and reaching surfaces waters, most are pharmaceutical drugs. In fact, concentrations of some pharmaceutical drugs (e.g.…”
