“…The high resistance of E. coli isolates to TET observed in Cascavel was similar to that observed in Lake Honghu in China, which was due to a high level of consumption, low cost, high effectiveness and low toxicity of the antibiotic (Wang et al, 2017). Resistance to TET has increased throughout decades of TET use for medical treatments; the indiscriminate use of antimicrobials generates a selective pressure on E. coli, leading to the selection of resistant strains (Reinthaler et al, 2003, Tenover, 2006.…”

“…It is a gram-negative bacillary bacterium, commonly found in the intestines of humans and animals, and is an important indicator of water, soil and food contamination (Wambugu et al, 2015;Osinska et al, 2017). The wide use of antimicrobials in the fight against infectious diseases results in a continuous release of these drugs into waters and soils (Wang et al, 2017). Selective pressure leads to an increase in the number of bacteria resistant to these antimicrobials (Cáceres & Muniesa, 2016;Chen et al, 2017).…”

Aquatic ecosystems of urban rivers are contaminated through waste disposal, which poses a public health problem. The objective of this research was to evaluate the quality of water used for recreation and public supply of six rivers in the city of Cascavel - Paraná, including Cascavel, Quati, Bezerra, Antas, Clarito and Amambay. Samples were collected every 4 months in 2017, and their physicochemical and microbiological parameters, as well as resistance profiles of strains of Escherichia coli to antimicrobials distributed by pharmacies of the primary healthcare network, were evaluated. Parameters such as water temperature, turbidity, total nitrogen, total phosphorus, total coliforms and thermotolerant coliforms showed significant differences. The allowed limit for thermotolerant coliforms, which was set by National Environment Council, Resolution 357/2005, was exceeded in all of the six analyzed rivers. It was determined that 48.1% of E. coli strains showed resistance to nine antimicrobial tested. The highest levels of resistance were found for ampicillin (27.7%), tetracycline (27.7%) and amoxicillin (24.0%). The results of this study contribute to the understanding of the hazards associated with the contamination of springs in urban centers with wastewater containing resistant bacteria. Therefore, recovery work is necessary in these areas because of the importance of these water sources for the entire western region of Paraná state.

“…Meanwhile, to evaluate the primary source of the antibiotics of Honghu lake, the waters from four major connecting rivers (i.e., R1 to R4) of Honghu lake and four typical aquaculture ponds (i.e., P1 to P4), which can exchange water with Honghu lake, were collected(Wang et al 2017b). In keeping with the Government Protection Zone definition(Zhang et al 2017) and in taking into account the different sources of pollution at each site(Wang et al 2017b) (treated sewage, crop, livestock, and fish aquaculture), all sampling sites were categorized into two groups—namely, the impacted and the less-impacted, control group(Zhang et al 2017). Sampling sites labeled L1, L2, P1, P2, P3, P4, R1, R2, R3, and R4 were classified as impacted, while sites labeled L3, L4, L5, L6, L7, L8, L9, and L10 were classified as less-impacted ( Figure 1 ).…”

BackgroundAgricultural activities, such as stock-farming, planting industry, and fish aquaculture, can influence the physicochemistry and biology of freshwater lakes. However, the extent to which these agricultural activities, especially those that result in eutrophication and antibiotic pollution, effect water and sediment-associated microbial ecology, remains unclear.MethodsWe performed a geospatial analysis of water and sediment associated microbial community structure, as well as physicochemical parameters and antibiotic pollution, across 18 sites in Honghu lake, which range from impacted to less-impacted by agricultural pollution. Furthermore, the co-occurrence network of water and sediment were built and compared accorded to the agricultural activities.ResultsPhysicochemical properties including TN, TP, NO3--N, and NO2--N were correlated with microbial compositional differences in water samples. Likewise, in sediment samples, Sed-OM and Sed-TN correlated with microbial diversity. Oxytetracycline and tetracycline concentration described the majority of the variance in taxonomic and predicted functional diversity between impacted and less-impacted sites in water and sediment samples, respectively. Finally, the structure of microbial co-associations was influenced by the eutrophication and antibiotic pollution.ConclusionThese analyses of the composition and structure of water and sediment microbial communities in anthropologically-impacted lakes are imperative for effective environmental pollution monitoring. Likewise, the exploration of the associations between environmental variables (e.g. physicochemical properties, and antibiotics) and community structure is important in the assessment of lake water quality and its ability to sustain agriculture. These results show agricultural practices can negatively influence not only the physicochemical properties, but also the biodiversity of microbial communities associated with the Honghu lake ecosystem. And these results provide compelling evidence that the microbial community can be used as a sentinel of eutrophication and antibiotics pollution risk associated with agricultural activity; and that proper monitoring of this environment is vital to maintain a sustainable environment in Honghu lake.

“…Fortunately, the discovery of the antibiotics in the twentieth century defended these lives against the attacks from various infection diseases owing to broad-spectrum antibacterial activity and easy availability. Therefore, massive antibiotics were produced in large scale for the clinic therapy of the infection diseases, and the annual consumption in the world reached about 100,000-200,000 tons (Kummerer, 2009;Wang et al, 2017). Unfortunately, not all the antibiotics can be completely consumed prior to the validity period.…”

Direct and Indirect Recycling Strategies of Expired Oxytetracycline for the Anode Material in Lithium Ion Batteries

et al. 2019

It is well-known that the antibiotics inhibit the wide spread of various infection diseases and guarantee the life safety of many patients. However, various waste antibiotics into the environment also pose the great challenges of the environmental contamination and the ecological poison. Unreasonable disposal of expired antibiotics is one of the main sources of waste antibiotics in the ecological environment. For this reason, in order to focus on the circular economy of such highly refined medical grade chemicals, expired oxytetracycline was recycled for the anode active material in lithium ion batteries (LIBs) by direct and indirect strategies. That is, it was directly used as the anode active material or recycled by two-step carbonization for LIBs anode. Furthermore, the effect of these two strategies on the electrochemical performances was also discussed. Both anode materials showed their individual advantages and high feasibility for LIBs anode. For example, both them delivered the satisfactory Li-storage performances. Additionally, the direct route possessed lower recycling cost and high recovery rate, while the application range of carbon material in the indirect route was broader.
