“…As a key factor, pH affects the degree of dissociation of the substances in solution and the electrical conductivity of the solution; furthermore, pH affects the formation rate, yield, and hydrogen and oxygen evolution of strong oxidizing intermediates, all of which affect the electrochemical reaction rate. To explore the influence of solution pH on the removal of oxytetracycline, experiments were carried out with different pH (3,5,7,9), while other conditions (current: 0.4 A, Na 2 SO 4 electrolyte concentration: 4 g/L, plate spacing: 2 cm) remained unchanged. As shown in Figure 2, the rate of oxytetracycline removal increased gradually with decreasing pH, and increased significantly when the pH of the solution gradually became acidic.…”

“…As a feed additive, they are directly added to aquaculture water. Microorganisms in the water can become resistant to the added antibiotics after long-term exposure to them in the environment, affecting the microbial community and aquatic organisms and destroying the aquatic ecosystem [7,8]. Additionally, antibiotics from various sources are eventually transported to water bodies, seep into groundwater, and contaminate drinking and tap water [9].…”

In this study, a Ti/IrO2-Ta2O5 anode was prepared by a hydrothermal method, and the prepared electrode was characterized by techniques such as scanning electron microscopy, X-ray diffraction, and electron dispersive spectroscopy. At the same time, the anode characteristics before and after electrochemical experiments were analyzed. The electrode gradation mechanism of oxytetracycline is discussed. In the whole experimental process, the range of electrolysis conditions was determined by single factor experiment, and then the optimal removal condition of oxytetracycline was determined by orthogonal experiments. The removal rate of oxytetracycline reached 99.02% after 20 min of electrolysis under the following optimal conditions: a current of 0.500 A, plate spacing of 2 cm, Na2SO4 electrolyte concentration of 4 g/L, and solution pH of 3. Additionally, the mechanism of oxytetracycline removal was explored, free radical scavenging experiments were performed, and the degradation mechanism was inferred based on the changes in the ultraviolet absorption of the oxytetracycline solution before and after electrolysis. Then, based on the liquid chromatography–mass spectrometry data, seven possible compounds and five possible removal pathways were proposed.

“…Waterways including rivers, lakes and some beach waters have been identified as a vector for ESBL-producing E. coli [10–16], with the main origin of these bacteria being human faeces rather than emergence of AMR within the waterway itself [17]. It has been found that the concentration of ESBL-producing E.…”

Whole genome sequence analysis of ESBL-producing Escherichia coli recovered from New Zealand freshwater sites

Extended-spectrum beta lactamase (ESBL)-producing Escherichia coli are often isolated from humans with urinary tract infections and may display a multidrug-resistant phenotype. These pathogens represent a target for a One Health surveillance approach to investigate transmission between humans, animals and the environment. This study examines the multidrug-resistant phenotype and whole genome sequence data of four ESBL-producing E . coli isolated from freshwater in New Zealand. All four isolates were obtained from a catchment with a mixed urban and pastoral farming land-use. Three isolates were sequence type (ST) 131 (CTX-M-27-positive) and the other ST69 (CTX-M-15-positive); a phylogenetic comparison with other locally isolated strains demonstrated a close relationship with New Zealand clinical isolates. Genes associated with resistance to antifolates, tetracyclines, aminoglycosides and macrolides were identified in all four isolates, together with fluoroquinolone resistance in two isolates. The ST69 isolate harboured the bla CTX-M-15 gene on a IncHI2A plasmid, and two of the three ST131 isolates harboured the bla CTX-M-27 genes on IncF plasmids. The last ST131 isolate harboured bla CTX-M-27 on the chromosome in a unique site between gspC and gspD. These data highlight a probable human origin of the isolates with subsequent transmission from urban centres through wastewater to the wider environment.

“…Their consumption increased tremendously in the last twenty years and a percent of about 30–90% is discharged in the environment in their native form or as metabolites [ 4 ]. Once entered the environment, antibiotics alter microbial communities and generate drug resistance in environmental bacteria via antibiotic resistance genes [ 5 ]. In this context, Swiacka et al [ 6 ] realized an extensive review related to the presence of different pharmaceuticals and their metabolites (antibiotics, analgesics, antidiabetics, antidepressants, NSAIDS, etc.)…”

Fish are able to accumulate by ingestion various contaminants of aquatic environment, with negative consequences on their intestine, being continuously threatened worldwide by heavy metals, pesticides and antibiotics resulted from the human activities. Consequently, the health of other species can be affected by eating the contaminated fish meat. In this context, our study aimed to perform a comparison between the changes in intestine samples of Carassius gibelio individuals collected from different artificial lakes in Bucharest (Romania), used by people for leisure and fishing. The presence of various metals, pesticides and antibiotics in the gut of fish was assessed in order to correlate their accumulation with changes of antioxidative enzymes activities and microbiome. Our results showed that fish from Bucharest lakes designed for leisure (Chitila, Floreasca and Tei lakes) have an increased level of oxidative stress in intestine tissue, revealed by affected antioxidant enzymes activities and GSH levels, as well as the high degree of lipid peroxidation, compared to the fish from protected environment (Vacaresti Lake). Some heavy metals (Fe, Ni and Pb) and pesticides (aldrin and dieldrin) were in high amount in the gut of fish with modified antioxidative status. In conclusion, our study could improve the knowledge regarding the current state of urban aquatic pollution in order to impose several environmental health measures.
