“…Similar results were obtained by Ávila et al [10], who found no significant differences when they evaluated the effect of operational and design parameters on ARG reductions (p > 0.05). Likewise, Sabri et al [11] did not observe significant changes in ARG (p > 0.05) in the water column, while the difference in ARG abundance could be seen only in the support medium. Abou-kandil et al [34] indicated that ARGs persisted in the biofilm formed on the support medium.…”

“…By contrast, Li et al [56] indicated a 16% higher ARG reduction in summer compared to those obtained during winter. Likewise, Sabri et al [11] evidenced negative correlations between temperature and ARG abundances. Abou-kandil et al [34] attributed these results to the fact that during summer, the metabolic activity and biomass responsible for ARG biodegradation intensified.…”

“…The occurrence of ARGs in influent with an average abundance of 2.0 × 10 7 copies/mL shows the risks associated with the occurrence of HTG and ARB proliferation. These processes can trigger the dissemination of AR into the environment [3,11]. Moreover, concentrations of antibiotics, pesticides, disinfectants, and heavy metals in sewage can increase this risk [6,49].…”

“…In addition, this result may indicate that flow configuration is not a determining factor in ARG reduction. Other factors must be taken into account to maximize the filtration, adsorption, and biodegradation mechanisms [11,30,34,49]. However, it is important to consider aeration as a relevant parameter when optimizing a CW to reduce ARGs in future studies.…”

“…Enterococcus sp., for example, are naturally resistant pathogens with the ability to acquire resistance to almost all available antibiotics [9]. Due to this, the contamination of surface water with antibiotics from treated and untreated sewage is considered to be the main cause of the rapid spread of AR in the environment [3,10,11].…”

The main objective of this review is to evaluate the performance of constructed wetlands (CWs) used to reduce antibiotic-resistant genes (ARGs) during sewage treatment. To accomplish this objective, statistical and correlation analyses were performed using published data to determine the influence of operational and design parameters on ARG reduction in CWs. The effects of design and operational parameters, such as different CW configurations, seasonality, monoculture and polyculture, support medium, and hydraulic retention time (HRT), on ARG removals, were analyzed. A comparison of ARG reduction under different CW configurations showed that the hybrid configuration of surface flow (SF)–vertical subsurface flow (VSSF) achieved the highest reductions, with values of 1.55 ulog. In this case, aeration is considered an important factor to reduce ARGs in CWs, and it should be considered in future studies. However, statistical analyses showed that the ARG reductions under different CW configurations were not significant (p > 0.05). The same behavior was observed when the effects of operational factors on ARG reductions were analyzed (p > 0.05). The results of this study show that CWs are not optimal technologies to reduce ARGs in sewage. The combination of CWs with advanced wastewater technologies can be a solution for enhancing ARG reduction and reducing the spread of antibiotic resistance.

As the Journal of Environmental Quality (JEQ) celebrates 50 years of publication, the division of environmental microbiology is one of the newest additions to the journal. During this time, significant advances in understanding of the interconnected microbial community and impact of the microbiome on natural and designed environmental systems have occurred. In this review, we highlight the intractable challenge of antimicrobial resistance (AMR) on humans, animals, and the environment, with particular emphasis on the role of integrated agroecosystems and by highlighting contributions published in JEQ. From early studies of phenotypic resistance of indicator organisms in waters systems to current calls for integrating AMR assessment across “One Health,” publications in JEQ have advanced our understanding of AMR. As we reflect on the state of the science, we emphasize future opportunities. First, integration of phenotypic and molecular tools for assessing environmental spread of AMR and human health risk continues to be an urgent research need for a one health approach to AMR. Second, monitoring AMR levels in manure is recommended to understand inputs and potential spread through agroecosystems. Third, baseline knowledge of AMR levels is important to realize the impact of manure inputs on water quality and public health risk; this can be achieved through background monitoring or identifying the source‐related genes or organisms. And finally, conservation practices designed to meet nutrient reduction goals should be explored for AMR reduction potential.
