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.

Exploring the Ameliorative Effects of Brassinolide on Microplastic-Induced Stress in the Rhizosphere Microecology of Pinellia Ternata

Опубликована: Янв. 1, 2025

Microplastics (MP) are found to exist in various environmental media because of their small particle size, large quantity and difficult decomposition. Farmland soil is regarded as a major pool source MP. Inevitably, the chemical properties microbial community will be impacted when MP enters soil. Brassinolide (BR) has been shown an ameliorator adverse effect on development Pinellia ternata. However, potential impact BR applications rhizosphere microecology P. ternata under interference not researched. In present study, was used test plant study influence foliar application its root characteristics, enzyme activity, community, physical properties. comparison with CK, length treatment combined significantly decreased by 22.8% 35.8% respectively. As compared group, catalase activity 12.5% increased urease 15.8%. The reduced pathogenic bacteria some extent improved effects caused above results revealed that had remediation composition pollution. purpose this understand agricultural quality measures.
