Chlorination-induced spread of antibiotic resistance genes in drinking water systems

Water Research, Journal Year: 2025, Volume and Issue: 274, P. 123092 - 123092

Published: Jan. 4, 2025

Chlorine, the most widely utilized disinfectant for drinking water globally, has recently been implicated in facilitating spread of antibiotic resistance genes (ARGs), raising concerns about its underestimated environmental and ecological risks. However, given current fragmented research focus results, a comprehensive understanding potential mechanisms influencing factors behind chlorination-promoted ARGs transmission systems is crucial. This work first to systematically review variations abundance, mechanisms, factors, mitigation strategies related during chlorination process. The results indicated that could induce genetic mutations promote horizontal gene transfer through multiple pathways, including increased reactive oxygen species, enhanced membrane permeability, stimulation SOS response, activation efflux pumps. In addition, this delves into significant discoveries regarding affecting ARG water, such as chlorine concentration, reaction time, disinfection byproducts, pipe materials, biofilms, matrix. A series effective from source point-of-use were proposed aimed at mitigating risks system. Finally, we address existing challenges outline future directions overcome these bottlenecks. Overall, aims advance our role dissemination inspire innovative ideas optimizing techniques, minimizing transmission, enhancing safety water.

Moving Beyond the Silos of Opportunistic Pathogen and Disinfection Byproduct Research to Improve Drinking Water System Management

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: May 2, 2025

Drinking water opportunistic pathogens (OPs) and disinfection byproducts (DBPs) both pose risks to public health, their variable occurrence from source tap complicates efforts control them simultaneously. Management of OPs DBPs is further hindered by the historical division between microbial chemical research. This review brings together current knowledge regarding DBPs, identifies factors that influence both, highlights areas where research needed better understand health risks. First, we examine understanding how are jointly influenced physicochemical parameters, characteristics, treatment processes including disinfection, distribution system properties. Temperature, for example, can affect OP DBP occurrence, higher temperatures promote growth some OPs, such as Legionella pneumophila, but temperature's effect on species-dependent. Methods quantifying associated with (quantitative risk assessment) (chemical compared, finding numerous assumptions data gaps each method limit comparability across contaminant types. We highlight urgent need fill existing develop a more unified framework so move toward holistic assessment provides suggestions future research, highlighting ways researchers might utilize established practices in or studies our other. For analysis organic matter composition, which has advanced formation, could be utilized elucidate characteristics OPs. bridges gap disciplines, arguing collaboration two address pressing challenges facing systems today.
