“…ETM has previously been identified as a potential ecological risk to aquatic biotas in rivers of China (Bu et al 2013;Chen et al 2017). Additionally, ETM, CLA, and azithromycin were included on a watch list of substances that could pose a significant ecological risk for aquatic environments in countries within the European Union (Välitalo et al 2017).…”

Lakes are an important source of freshwater, containing nearly 90% of the liquid surface fresh water worldwide. Long retention times in lakes mean pollutants from discharges slowly circulate around the lakes and may lead to high ecological risk for ecosystem and human health. In recent decades, antibiotics and antibiotic resistance genes (ARGs) have been regarded as emerging pollutants. The occurrence and distribution of antibiotics and ARGs in global freshwater lakes are summarized to show the pollution level of antibiotics and ARGs and to identify some of the potential risks to ecosystem and human health. Fifty-seven antibiotics were reported at least once in the studied lakes. Our meta-analysis shows that sulfamethoxazole, sulfamerazine, sulfameter, tetracycline, oxytetracycline, erythromycin, and roxithromycin were found at high concentrations in both lake water and lake sediment. There is no significant difference in the concentration of sulfonamides in lake water from China and that from other countries worldwide; however, there was a significant difference in quinolones. Erythromycin had the lowest predicted hazardous concentration for 5% of the species (HC) and the highest ecological risk in lakes. There was no significant difference in the concentration of sulfonamide resistance genes (sul1 and sul2) in lake water and river water. There is surprisingly limited research on the role of aquatic biota in propagation of ARGs in freshwater lakes. As an environment that is susceptible to cumulative build-up of pollutants, lakes provide an important environment to study the fate of antibiotics and transport of ARGs with a broad range of niches including bacterial community, aquatic plants and animals.

“…O ver the past few decades, one typical antibiotic, oxytetracycline (OTC), has been widely used in treating human and animal infections. The residue of OTC has been detected in water environment, resulting in the formation of antibiotic resistance bacteria, which pose great threats to both human and livestock (Chen et al, 2018). Besides, conventional water treatment could hardly eliminate antibiotic residue, due to its stable chemical property.…”

Retracted: The Fabrication of Magnetically Recyclable La-Doped TiO₂/Calcium Ferrite/Diatomite Composite for Visible-Light-Driven Degradation of Antibiotic and Disinfection of Bacteria

Powdery photocatalyst has been deeply studied due to its great potential in water treatment, yet its low recyclability is the bottleneck hindering its practical application. In this work, magnetically recyclable lanthanum-doped TiO 2 /calcium ferrite/diatomite (La-TCD) ternary composite was synthesized by sol-gel method. The physicochemical properties of this material were characterized and studied, and the photocatalytic property was evaluated by the decomposition of antibiotic oxytetracycline (OTC) and disinfection of bacteria Escherichia coli under visible light irradiation. The formation of heterojunction between La-doped TiO 2 and calcium ferrite hindered the recombination of photo-induced charge carriers and improved the photocatalytic activity. Besides, the photodecomposition of OTC was enhanced by the high adsorption ability of substrate diatomite, in other words, the adsorption and decomposition synergistic behavior between catalyst and diatomite. The optimal La doping amount, as well as composite dosage, was determined. The composite could simply be recovered from waterbody by an external magnet, and the repetition tests indicated no obvious decrease of photoactivity after five cycles. Above all, this composite presented good potential to be applied in wastewater remediation process.

“…At the same time, TCs were commonly administered to livestock for the prevention and treatment of most respiratory infection and diarrhea ( Matsui et al, 2008 ) and their usage tended to increase in winter ( Cheng et al, 2014 ). Under the influence of these factors, most studies found that the concentration of antibiotics in the water body was higher in the dry season ( Yan et al, 2013 ; Chen et al, 2018 ). The seasonal variation in antibiotics would produce a selective pressure, so the abundance of ARG in winter would be higher ( Caucci et al, 2016 ; Sui et al, 2017 ).…”

The widespread use of antibiotics and the induced antibiotic resistance genes have attracted much attention in recent years. The longshore sediments in the water-level-fluctuating zone of the Three Gorges Reservoir were selected to investigate the spatial-temporal distribution of antibiotics and antibiotic resistance genes in two different operation stages (low-water level in summer and high-water level in winter). Three kinds of tetracycline antibiotics (tetracycline, oxytetracycline, and chlortetracycline) and three kinds of tetracycline resistance genes [tet(A), tet(C), and tet(M)] were analyzed and quantified. The results showed that the distribution of tetracyclines and resistance genes in riverine, transition and lacustrine zones showed a certain regularity, and the tetracycline antibiotics concentration and the total abundance of the tetracycline resistance genes were highest in the transition zone, and then the riverine zone. Meanwhile, there were significant seasonal variations of tetracycline and the resistance genes. The concentrations of the tetracycline and resistance genes were higher in summer than those in winter, while the relative abundance of resistance genes was higher in winter. It was suggested that the different seasonal distribution of antibiotics and resistance genes may be correlated with the reservoir operation in the Three Gorges Reservoir and the higher use of antibiotics in winter. In addition, Pearson correlation analysis showed that the concentrations of the tetracycline, class 1 integron and 16S rRNA were positively correlated with the abundance of the tetracycline resistance genes.
