Abstract Microplastic (MP) pollution likely affects global soil carbon (C) dynamics, yet it remains uncertain how and to what extent MP influences respiration. Here, we report on a meta‐analysis determine the effects of microbiome CO 2 emission. We found that significantly increased contents organic C (SOC) (21%) dissolved (DOC) (12%), activity fluorescein diacetate hydrolase (FDAse) (10%), microbial biomass (17%), but led decrease in diversity (3%). In particular, increases components further promote emission (25%) from soil, with much higher effect MPs these emissions than biomass. The could be attributed opposite vs. diversity, as accumulation recruited some functionally important bacteria provided additional substrates for specific heterotrophic microorganisms, while inhibiting growth autotrophic taxa (e.g., Chloroflexi , Cyanobacteria ). This study reveals can increase by causing shifts microbiome. These results underscore potential importance plastic terrestrial fluxes, thus climate feedbacks.

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.

Microplastics (MPs) and antibiotic resistance genes (ARGs) pose significant challenges to the One Health framework due their intricate multifaceted ecological environmental impacts. However, understanding of how MP properties influence ARG prevalence in mariculture sediments remains limited. Herein, polystyrene (PS) polyvinyl chloride (PVC) MPs with different sizes (20-120 μm 0.5-2.0 mm) were selected evaluate impacts underlying mechanisms driving ARGs dissemination. The results showed that PS PVC increased relative abundance by 1.41-2.50-fold 2.01-2.84-fold, respectively, compared control, particularly high-risk genes. polymer type effect was identified as more influential than size sediment resistome evolution. shifted microbial community assembly from stochastic deterministic processes, thus enriching host pathogens. Furthermore, highly hydrophobic not only recruited bacteria colonization but also facilitated exchange within plastisphere. exogenous additives released (e.g., heavy metals, bisphenol A, tridecyl ester) particles synergistically promoted conjugative transfer inducing oxidative stress enhancing cell membrane permeability. These findings revealed characteristics spread marine benthic ecosystems, underscoring importance mitigating pollution maintain ecosystem health, prevent zoonotic diseases, balance global health.

Microorganisms colonizing the surfaces of microplastics form a plastisphere in environment, which captures miscellaneous substances. The plastisphere, owning to its inherently complex nature, may serve as "Petri dish" for development and dissemination antibiotic resistance genes (ARGs), adding layer complexity tackling global challenge both ARGs. Increasing studies have drawn insights into extent proliferation ARGs occurred presence micro/nanoplastics, thereby increasing antimicrobial (AMR). However, comprehensive review is still lacking consideration current increasingly scattered research focus results. This focuses on spread mediated by microplastics, especially challenges perspectives determining contribution AMR. accumulates biotic abiotic materials persistent surfaces, which, turn, offers preferred environment gene exchange within across boundary plastisphere. Microplastics breaking down smaller sizes, such nanoscale, can possibly promote horizontal transfer environmental stressors inducing overgeneration reactive oxygen species. Additionally, we also discussed methods, quantitatively comparing ARG profiles among different samples this emerging field that multidimensional parameters are great necessity systematically determine risk Finally, based biological sequencing data, offered framework assess AMR risks micro/nanoplastics biocolonizable microparticles leverage AMR-associated messages, including ARGs' abundance, mobility, potential acquisition pathogens.

The environmental dissemination of extracellular antibiotic resistance genes (eARGs) in wastewater and natural water bodies has aroused growing ecological concerns. coexisting chemical pollutants are known to markedly affect the eARGs transfer behaviors microbial community, but detailed interactions specific impacts remain elusive so far. Here, we revealed a concentration-dependent impact dimethyl phthalate (DMP) several other types esters (common released from plastics) on transformation eARGs. DMP exposure at an environmentally relevant concentration (10 μg/L) resulted 4.8-times raised frequency Acinetobacter baylyi severely suppressed high (1000 μg/L). promotion by low-concentration was attributed multiple mechanisms, including increased bacterial mobility membrane permeability facilitate uptake improved DMP-bounded (via noncovalent interaction) enzymatic degradation (with DNase activity). Similar promoting effects were also found real biofilm systems. In contrast, higher-concentration disrupting DNA structure. Our findings highlight potentially underestimated spreading aquatic environments due deepen our understanding risks biological-chemical combined pollution bodies.
