A Mini-Review of Antibiotic Resistance Drivers in Urban Wastewater Treatment Plants: Environmental Concentrations, Mechanism and Perspectives
AI summary Read the abstract
This review examines the drivers of antibiotic resistance in urban wastewater treatment plants, including antibiotics, heavy metals, disinfectants, personal care products, and microplastics. Researchers summarized the concentration levels and mechanisms by which these chemical pollutants promote the development and spread of antibiotic-resistant bacteria and genes. The study emphasizes the importance of studying these interactions under realistic conditions to better understand and mitigate antibiotic resistance in wastewater systems.
Antibiotic resistance is one of the biggest challenges to public health and ecological safety in the 21st century. Urban wastewater treatment plants (UWTPs), as reservoirs of antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB), simultaneously contain a wide variety of chemical pollutants. The review introduces the actual concentration levels and the mechanisms of antibiotic resistance drivers (ARDs) in UWTPs, including antibiotics, heavy metals, disinfectants, cosmetics and personal care products, non-antibiotic drugs, and microplastics. Moreover, this review emphasizes the importance of approaching the actual activated sludge environment in future research and proposes future directions.

Antibiotic and Non-Antibiotic Determinants of Antimicrobial Resistance: Insights from Water Ecosystems
AI summary Read the abstract
This review explains how non-antibiotic pollutants like heavy metals, biocides, and microplastics are contributing to antibiotic resistance in water systems, beyond the well-known problem of antibiotic overuse. Wastewater treatment plants are hotspots where these pollutants interact with bacteria, promoting the spread of resistance genes through mobile genetic elements. The findings are concerning for human health because drug-resistant bacteria from water environments can ultimately reach people through drinking water and food.

Unveiling the Interactions Between the Antibiotic Resistome and Microplastics Influenced by Trace Elements and PPCPs in Wastewater Treatment Plants
AI summary Read the abstract
This study investigated how microplastics, trace elements (copper and zinc), and pharmaceuticals/personal care products interact in wastewater treatment plants to influence the spread of antibiotic resistance genes. The findings revealed that co-occurrence of these pollutants promoted the persistence and spread of the antibiotic resistome beyond what any individual contaminant caused.
