“…It has been reported that animal-derived food plays a key role in human exposure to antibiotics via dietary intake. , Due to the decreasing tendency in antibiotic usage per ton of animal products in China since 2014, the rise in concentrations of antibiotics in the urine collected from the general population in the test areas in 2020 (compared to 2017) was likely due to increased intake of antibiotics (self-medication) during the COVID-19 pandemic, especially considering the relatively lower bioavailability of antibiotics through oral uptake than via intravenous injection . Moreover, consistent with the above-mentioned results, relatively higher levels of sulfadiazine, sulfamethoxazole, and sulfamethazine (divided into the sulfonamide group), as well as ofloxacin (divided into the fluoroquinolone group), were found in the receiving rivers of sewage across Shanghai in November 2020 (range: nd to 76.7, 8.83–35.1, 10.9–332, and nd to 40.0 ng/L) than those in November 2014 (nd to 53.9, nd to 26.0, nd to 10.1, and nd to 16.1 ng/L). , …”

The outbreak of the novel coronavirus 2019 (COVID-19) pandemic has resulted in the increased human consumption of medicines. Antibiotics are of great concern due to their adverse effects, such as increased bacterial resistance and dysbiosis of gut microbiota. Nevertheless, very little is known about the changes in self-medication with antibiotics during the COVID-19 pandemic and the resultant potential health risks. Herein, we examined the concentration profiles of some commonly used antibiotics in human urine collected from several geographical regions in China between 2020 and 2021. Antibiotics were found in 99.2% of the urine samples at concentrations ranging from not detected (nd) to 357 000 (median: 10.2) ng/mL. During the COVID-19 pandemic, concentrations of urinary antibiotics were remarkably higher than those found either before the pandemic or in the smooth period of the pandemic. Moreover, elevated levels of antibiotics were determined in urine samples from the regions with more confirmed cases. The exposure assessment showed that hazard index values >1 were determined in 35.2% of people. These findings show that human exposure to antibiotics increased during the COVID-19 pandemic, and further research is imperative to identify the public health risks.

“…These antibiotic residues, which are excreted directly or indirectly from hospitals (waste and wastewater), animal breeding facilities, industrial facilities, aquaculture fields and human feces or urine reach wastewater treatment plants. (Kümmerer et al 2000;Li et al 2021). Since almost all general wastewater treatment plants in the world are designed on the basis of removing C, N, P and some other main pollutants, it has been proven by many studies that these existing wastewater treatment plants are not sufficient for the removal of antibiotics (Al-Gheethi et al 2015;Lien et al 2016;Russell and Yost 2021).…”

This study aims to remove oxytetracycline (OTC), that harms the ecosystem, with activated carbon (LPAC) obtained from Lemon Pulp (LP). Characterization and properties of LPAC were analyzed by Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy (FTIR), Scanning Electron Microscope (SEM), X-ray diffraction (XRD) and Point of Zero Charge (pHPZC) analyses.BET surface area, pore volume and pHPZC of LPAC produced by carbonization at 400 0 C and activation with KOH at 800 0 C were obtained as 1333.01 m 2 /g, 0.391 cm 3 /g and 6.81, respectively. pH, reaction time, initial OTC concentration and adsorbent amounts were optimized in the adsorption study performed with LPAC with high porosity and micropores. Kinetic evaluation was made with Pseudo-First-Order, Pseudo-Second-Order and Intra-Particle Diffusion Models and Freundlich, Langmuir and Temkin equations are used to investigate their isotherms under reaction equilibrium conditions and also the results were analyzed by statistical method (ANOVA). In Pseudo Second Order kinetic and Freundlich isotherm models, where the best results were obtained, R 2 values were calculated as 0.9988 and 0.9953, respectively. Maximum OTC removal efficiency was found as 104.222 mg/g. Overall, this research indicates that LPAC for the treatment of water contaminated with antibiotics is environmentally friendly green material.
