“…Among the major point sources of environmental contamination from antibiotics are the UWTPs known for their low efficiency in removing such contaminants by the CAS process. 17 For example, Lindberg et al 18 reported that ciprofloxacin is not readily biodegradable in wastewater during CAS treatment and that 70% of its total amount is adsorbed to sludge. Consequently, antibiotic-resistant bacteria (ARB), including multiple-antibiotic resistant bacteria, have been detected in UWTPs.…”

BACKGROUND This study aims at evaluating the degradation of the antibiotic ciprofloxacin (CIP) in urban wastewater effluents using a UV‐C‐driven oxidation processes in the presence of hydrogen peroxide. Under the optimum experimental conditions, the phytotoxicity and ecotoxicity of the treated samples were investigated against one plant species (Sinapis alba) and a crustacean (Daphnia magna), respectively. The efficiency of the process to remove E. coli and ciprofloxacin‐resistant E. coli was also assessed. RESULTS Complete degradation of CIP was achieved within 15 min of treatment under the optimum concentration of the oxidant ([H2O2] = 10 mg L−1). The degradation rate of the antibiotic fitted pseudo‐first‐order kinetics. An increase in both shoot inhibition and root inhibition was observed, until 60 min of treatment, beyond which, the phytotoxic effect was eliminated. The results demonstrated the ability of the UV‐C process to reduce the toxicity towards D. magna by 40%, comparatively, to the untreated wastewater. The inactivation of E. coli and CIP‐resistant E. coli was achieved within 2 min of treatment. CONCLUSIONS The UV‐C/H2O2 process was successfully applied for the removal of CIP at low environmental concentration level. The treatment process was able to achieve a significant reduction of phyto‐ and eco‐toxic effects, as well as E. coli harbouring resistance to CIP. © 2016 Society of Chemical Industry

“…Due to the extensive application and wide-spectrum use of ABs in recent decades, AB residues are now frequently being detected in raw or treated wastewater (WW) [7][8][9] , hospital effluents 2,10,11 , surface water 2,[12][13][14] , groundwater 15,16 , and soil sediments in the natural systems 6,17 . The range of concentration is from ng L −1 (norfloxacin, 11.1-964 ng L −1 ) 8 to mg L −1 (ciprofloxacin, 28-31 mg L −1 ) 18 . Owing to the reality that ABs can cause severe damage to the aquatic and human life even in trace concentrations, their buildup in the environment and way up to the trophic levels has been recognized as one of the gravest environmental issues to policymakers and industry personnel worldwide 16 .…”

Proclivities for prevalence and treatment of antibiotics in the ambient water: a review

et al. 2020

In the intial two decades of the twenty-first century, antibiotic (AB) resistance in human pathogens has emerged as a major challenge for water, sanitation, and public health. Considering these challenges, we critically reviewed AB-related studies with particular emphasis on their (i) patterns of consumption, (ii) pathway prevalences and environmental implications in ambient waters, and (iii) benefits and limitations of existing AB removal/purging techniques. We found that lifestyle, land use, urbanization, the ease of availability, and the tendency of the medical practitioners to recommend ABs are the key factors governing the AB use pathway and enrichment in the environment. In the developing world, the most prevalent group of ABs is quinolone, whereas in the developed world, older-generation AB groups are most prevalent. Further, enormous variability in the consumption of ABs around the globe is explicitly highlighted in this study. Ciprofloxacin has been reported in the highest concentration among all the ABs with 28–31 mg L−1 in the raw wastewater of the Indian subcontinent. We found that adsorption may be one of the most efficient AB removal techniques, and NaOH-activated carbon prepared from Macadamia nut shells is the most effective adsorbent identified to date. The literature showed that the Langmuir isotherm and pseudo-second-order kinetic model explain the AB adsorption mechanism most effectively. The future challenge lies in developing advanced protocols and markers to prioritize the strategy and simulate the ecotoxicities of the individual and a mixture of ABs.

“…The higher residual concentrations of SAs were found in hospital and pharmaceutical wastewater [7]. Sulfisoxazole was found to reach 157.7 ng/L in wastewater treatment plants (WWTP) influent, and sulfadiazine in WWTP effluent reached 960 ng/L in China [8–9]. Sulfamethazine was not detected in airborne particulate matter collected near dairy production facilities [10], but it was found in dust samples collected from a pig‐fattening farm in Germany [11].…”

In the present research, field-amplified sample injection-CZE (FASI-CZE) coupled with a diode array detector was established to determine trace level sulfa antibiotic. Sulfathiazole, sulfadiazine, sulfamethazine, sulfadimethoxine, sulfamethoxazole, and sulfisoxazole were selected as analytes for the experiments. The background electrolyte solution consisted of 70.0 mmol/L borax and 60.0 mmol/L boric acid (including 10% methanol, pH 9.1). The plug was 2.5 mmol/L borax, which was injected into the capillary at a pressure of 0.5 psi for 5 s. Then the sample was injected into the capillary at an injection voltage of-10 kV for 20 s. The electrophoretic separation was carried out under a voltage of +19 kV. The capillary temperature was maintained at 20˚C throughout the analysis, and six sulfonamides were completely separated within 35 min. Compared with pressure injection-CZE, the sensitivity of FASI-CZE was increased by 6.25-10.0 times, and the LODs were reduced from 0.2-0.5 to 0.02-0.05 μg/mL. The method was applied to the determination of sulfonamides in river water and particulate matter samples. The recoveries were 78.59-106.59%. The intraday and interday precisions were 2.89-7.35% and 2.77-7.09%, respectively. This provides a simpler and faster method for the analysis of sulfa antibiotic residues in environmental samples.
