“…Opposite to chlorine, which did not affect plasmid DNA structure at the studied doses, ozone and photocatalytic treatment resulted in conformational changes and the damage increased with increasing oxidant doses. When Fenton and ozone oxidation processes were investigated in the removal of tetM gene and its host E. coli HB101 from synthetically contaminated cow manure, PCR-based monitoring assays showed that the band intensity of the tetM gene gradually decreased by increasing the Fenton reagent and the applied ozone dose (Cengiz et al, 2010). A different approach was used by Paul et al (2010) to evaluate the effects of photolytic and TiO 2 photocatalytic treatment processes on the antibacterial activity of ciprofloxacin.…”

Urban wastewater treatment plants (UWTPs) are among the main sources of antibiotics' release into the environment. The occurrence of antibiotics may promote the selection of antibiotic resistance genes (ARGs) and antibiotic resistant bacteria (ARB), which shade health risks to humans and animals. In this paper the fate of ARB and ARGs in UWTPs, focusing on different processes/technologies (i.e., biological processes, advanced treatment technologies and disinfection), was critically reviewed. The mechanisms by which biological processes influence the development/selection of ARB and ARGs transfer are still poorly understood. Advanced treatment technologies and disinfection process are regarded as a major tool to control the spread of ARB into the environment. In spite of intense efforts made over the last years to bring solutions to control antibiotic resistance spread in the environment, there are still important gaps to fill in. In particular, it is important to: (i) improve risk assessment studies in order to allow accurate estimates about the maximal abundance of ARB in UWTPs effluents that would not pose risks for human and environmental health; (ii) understand the factors and mechanisms that drive antibiotic resistance maintenance and selection in wastewater habitats. The final objective is to implement wastewater treatment technologies capable of assuring the production of UWTPs effluents with an acceptable level of ARB.

“…Other AOPs, e.g., UV/H2O2-mediated oxidation, photo-Fenton, TiO2 photocatalysis, or activated-persulfate oxidation, have also been demonstrated to be effective in removing ARB&ARG from conventionally treated wastewater (Cengiz et al 2010;Michael et al 2012;Michael-Kordatou et al 2015;Ferro et al 2015). However, it is still an open question whether the operational conditions of AOPs may select bacteria with higher capacity to resist oxidative stress conditions (e.g., enhanced defense mechanisms, horizontal gene transfer, or mutation rates).…”

Over the last decade, numerous evidences have contributed to establish a link between the natural and human-impacted environments and the growing public health threat that is the antimicrobial resistance. In the environment, in particular in areas subjected to strong anthropogenic pressures, water plays a major role on the transformation and transport of contaminants including antibiotic residues, antibiotic-resistant bacteria, and antibiotic resistance genes. Therefore, the urban water cycle, comprising water abstraction, disinfection, and distribution for human consumption, and the collection, treatment, and delivery of wastewater to the environment, is a particularly interesting loop to track the fate of antibiotic resistance in the environment and to assess the risks of its trans-mission back to humans. In this article, the relevance of different transepts of the urban water cycle on the potential enrichment and spread of antibiotic resistance is reviewed. According to this analysis, some gaps of knowledge, research needs, and control measures are suggested. The critical rationale behind the measures suggested and the desirable involvement of some key action players is also discussed.

“…Numerous studies have investigated the efficacy of solar-powered Fenton oxidation and ozonation on P. aeruginosa and ARGs [ 87 ]. Since the 1950s, ozone treatment has been used to treat hospital wastewater, and several studies have demonstrated its effectiveness in eliminating a range of pathogens, including P. aeruginosa [ 88 ].…”
