“…High SMX loading inhibited growth of anaerobic microorganisms. Oliveira et al (2019) demonstrated the potential of treating antibiotic sulfamethazine (SMZ) by horizontal flow-anaerobic immobilized biomass reactor. Yu, Wang, et al (2019) reported that magnetic humic acid (MHA) nanoparticle enhanced azo dye degradation under elevated salt concentration.…”

“…The technique was performed over the frequency range from 10 000 to 0.1 Hz at an AC potentiostatic pertubation with amplitude of 10 mV around the open circuit potential (OCP). All the measurements were performed aer monitoring the OCP for 300 s in a solution containing 0.01 mol L À1 PBS (pH 7.4), 0.1 mol L À1 KCl as the supporting electrolyte and 0.005 mol L À1 K 3 [Fe(CN) 6 ]/ K 4 [Fe(CN) 6 ] as the redox probe. The recorded EIS data were modelled to an electrical equivalent circuit using Zview 2.9b soware.…”

“…Thus, antibiotics in the environment are considered as a major threat to human health and aquatic ora and fauna, even at the extremely low concentrations found in the environment, such as micrograms and nanograms per liter. [6][7][8] Currently, there is great concern about multi-resistant bacteria occurring in wastewater treatment plants (WWTPs), since these units were not designed to remove ECs and provide an environment that is favorable for microorganism multiplication. 1,2,6,[9][10][11][12] It is known from the literature 2,13-17 that pharmaceutical compounds may be partially degraded (producing more toxic sub-products) or may remain unchanged during conventional treatment in WWTPs and then be released into water bodies.…”

In this study an impedimetric immunosensor was developed in order to determine ciprofloxacin (CIP) in wastewater samples, an emergent contaminant widely found in wastewater. To achieve this, an anticiprofloxacin antibody was immobilized on the surface of a printed carbon electrode. Then, the developed immunosensor was applied in wastewater samples from Université Laval residences (Québec, Canada) through the load transfer resistance (R ct ) using [Fe(CN) 6 ] 3À/4À as a redox probe, and the average CIP concentration was found to be 2.90 Â 10 À4 mg mL À1 . The observed R ct changes presented a linear relationship from CIP concentrations of 10 À5 to 1.0 mg mL À1 , with detection and quantification limits of 2.50 Â 10 À6 and 7.90 Â 10 À6 mg mL À1 , respectively. The immunosensor presented high selectivity and repeatability, as well as a good recovery rate in wastewater samples (97%). Significant interference with other compounds was not observed. The proposed method requires only 30 mL of sample without the use of organic solvents or preceding sample preparation and/or extraction techniques. Moreover, the method is fast: only 20 min of incubation followed by 2 min of analysis time was sufficient to obtain the CIP concentration. The method's estimated cost is U$ 2.00 per sample.

Emerging contaminants are substances found in the environment whose concentrations vary from µg to ng L-1 and whose presence in wastewater has gained popularity in the scientific community due to the potential impacts these compounds can cause to the environment. This designation concerns the lack of legislation to regulate their discharge or even to monitor these compounds. Moreover, emerging contaminants are capable of causing harmful effects to nontarget organisms and therefore affect the ecosystem balance. There are several compounds classified as emerging contaminants such as pharmaceuticals, illicit drugs, hormones, pesticides, among others. And among them, caffeine is considered an emerging contaminant and can be highlighted due its presence in medicines, beverages, foodstuff and several other products. In addition, it is a compound used worldwide recognized as a marker of anthropogenic activity. In this review, we present a discussion about emerging contaminants, focusing on caffeine, regulatory aspects that involve the theme, as well as effects on organisms, removal technologies and techniques for analyzing these compounds in environmental matrices.
