“…Comparing the removal efficiency of each antibiotic separately, we found that the removal efficiencies varied largely from –1084.8% to 100% for the detected antibiotics in four PMFs (Table 3). Among the 17 antibiotics investigated, the highest removal efficiency was for norfloxacin, reaching 100%, which was similar to the value (93.9%) at the PMFs from Qingdao, China (Wang et al, 2021). Sulfapyridine and sulfamethoxazole were the second highest, and their average removal efficiency was 90.3% and 89.6%, respectively.…”

“…The negative removal efficiency of several antibiotics, including ciprofloxacin, clarithromycin, erythromycin-H 2 O, lincomycin, ofloxacin, and so forth, were observed in the studied PMFs, which were also reported in previous works (Cardoso et al, 2014; Larsson et al, 2007). For example, the removal efficiency of lincomycin in two PMFs in Qingdao was reported to be – 100% to 98.4% (Wang et al, 2021). The negative removal efficiency of antibiotics was observed in PMFs, which might be due to several reasons: (i) transformation of the conjugated forms into parent compounds by microorganisms (Jelic et al, 2011), (ii) release of the antibiotics enclosed in fecal particles (Göbel et al, 2007), and (iii) sampling strategies and uncertainties of sample treatments and measurements (Jelic et al, 2011; Tran et al, 2016).…”

This study aimed to update information on the presence and persistence of antibiotics in wastewater from four typical pharmaceutical plants in China and the removal of antibiotics by the wastewater treatment process. It also evaluated the environmental impact of antibiotic residues through wastewater discharge into receiving water bodies. The results indicated that 13 antibiotics were detected in wastewater samples with concentrations ranging from 57.03 to 726.79 ng/L. Fluoroquinolones (FQs) and macrolides (MLs) were the most abundant antibiotic classes in wastewater samples, accounting for 42.5% and 38.7% of total antibiotic concentrations, respectively, followed by sulfonamides (SAs) (16.4%) and tetracyclines (TCs) (2.4%). Erythromycin-H2O (ERY), lincomycin (LIN), ofloxacin (OFL), and trimethoprim (TMP) were the most frequently detected antibiotics; among these antibiotics, the concentration of OFL was the highest in most wastewater samples. No significant difference was found in the removal of antibiotics between different treatment processes, and more than 50% of antibiotics were not completely removed with a removal efficiency of less than 70%. The concentration of detected antibiotics in the receiving water was an order of magnitude lower than that in the wastewater due to dilution. Finally, an environmental risk analysis showed that lincomycin and ofloxacin could pose a high risk at the concentrations detected in effluents and a medium risk in their receiving waters, highlighting that they were a potential hazard to the health of the aquatic ecosystem.

“…The massive levels of pollutants released into water sources worldwide due to increased population expansion and industrial development have generated adverse environmental effects in recent decades [ 1 , 2 , 3 , 4 ]. The effluents from textile industries, particularly synthetic dyes, discharged without proper treatment and management adversely affect our environment in one way or another [ 1 ].…”

“…Moreover, synthetic dyes, present in many industrial wastewaters, are highly stable molecules and are difficult to degrade by conventional physicochemical processes [ 2 ]. The dyes and antibiotics in the wastewater of pharmaceutical plants and industrial effluents are among the most serious and hazardous pollutants that must be removed from the wastewater before discharging [ 3 ]. These toxic and dangerous substances are harmful and cannot be removed through conventional methods such as physical adsorption and biochemical techniques [ 4 ].…”

Design and Preparation of Biomass-Derived Activated Carbon Loaded TiO2 Photocatalyst for Photocatalytic Degradation of Reactive Red 120 and Ofloxacin

The design and development of novel photocatalysts for treating toxic substances such as industrial waste, dyes, pesticides, and pharmaceutical wastes remain a challenging task even today. To this end, a biowaste pistachio-shell-derived activated carbon (AC) loaded TiO2 (AC-TiO2) nanocomposite was fabricated and effectively utilized towards the photocatalytic degradation of toxic azo dye Reactive Red 120 (RR 120) and ofloxacin (OFL) under UV-A light. The synthesized materials were characterized for their structural and surface morphology features through various spectroscopic and microscopic techniques, including high-resolution transmission electron microscope (HR-TEM), field emission scanning electron microscope (FE-SEM) along with energy dispersive spectra (EDS), diffuse reflectance spectra (DRS), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, photoluminescence spectra (PL) and BET surface area measurements. AC-TiO2 shows enhanced photocatalytic activity compared to bare TiO2 due to the change in the bandgap energy and effective charge separation. The degradation rate of dyes was affected by the bandgap of the semiconductor, which was the result of the deposition weight percentage of AC onto the TiO2. The presence of AC influences the photocatalytic activity of AC-TiO2 composite towards RR 120 and OFL degradation. The presence of heteroatoms-enriched AC enhances the charge mobility and suppresses the electron-hole recombination in AC-TiO2 composite, which enhances the photocatalytic activity of the composite. The hybrid material AC-TiO2 composite displayed a higher photocatalytic activity against Reactive Red 120 and ofloxacin. The stability of the AC-TiO2 was tested against RR 120 dye degradation with multiple runs. GC-MS analyzed the degradation intermediates, and a suitable degradation pathway was also proposed. These results demonstrate that AC-TiO2 composite could be effectively used as an ecofriendly, cost-effective, stable, and highly efficient photocatalyst.

“…Most antibiotics cannot be completely metabolized after entering the organism, and 50–90% of them ultimately reach the aquatic environment through urine or feces [ 8 ]. Antibiotic concentrations in China have reached nanogram or even milligram levels today [ 9 ], as they are difficult to degrade and easy to enrich in the ecosystem due to their environmental persistence and bioaccumulation. Thus, they may accumulate in the environment and organisms for an extended period of time.…”

The hazards of antibiotics as emerging contaminants to aquatic ecosystems and human health have received global attention. This study investigates the presence, concentration levels, spatial and temporal distribution patterns, and their potential risks to aquatic organisms and human health of sulfonamides (SAs) in the Shaanxi section of the Weihe River. The SA pollution in the Weihe River was relatively less than that in other rivers in China and abroad. The spatial and temporal distribution showed that the total concentrations of SAs in the Weihe River were highest in the main stream (ND–35.296 ng/L), followed by the south tributary (3.718–34.354 ng/L) and north tributary (5.476–9.302 ng/L) during the wet water period. Similarly, the order of concentration from highest to lowest during the flat water period was main stream (ND–3 ng/L), north tributary (ND–2.095 ng/L), and south tributary (ND–1.3 ng/L). In addition, the ecological risk assessment showed that the SAs other than sulfadiazine (SDZ) and sulfamethoxazole (SMZ) posed no significant risk (RQS < 0.01) to the corresponding sensitive species during both periods, with no significant risk to human health for different age groups, as suggested by the health risk assessment. The risk of the six SAs to both aquatic organisms and human health decreased significantly from 2016 to 2021.
