Toxicity Mechanisms of Nanoplastics on Crop Growth, Interference of Phyllosphere Microbes, and Evidence for Foliar Penetration and Translocation

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 58(2), P. 1010 - 1021

Published: Nov. 7, 2023

Despite the increasing prevalence of atmospheric nanoplastics (NPs), there remains limited research on their phytotoxicity, foliar absorption, and translocation in plants. In this study, we aimed to fill knowledge gap by investigating physiological effects tomato leaves exposed differently charged NPs absorption NPs. We found that positively caused more pronounced effects, including growth inhibition, increased antioxidant enzyme activity, altered gene expression metabolite composition even significantly changed structure phyllosphere microbial community. Also, exhibited differential translocation, with penetrating into dispersing uniformly within mesophyll cells. Additionally, absorbed were able translocate roots. These findings provide important insights interactions between crop plants demonstrate NPs' accumulation crops could negatively impact agricultural production food safety.

Photo-oxidation of Micro- and Nanoplastics: Physical, Chemical, and Biological Effects in Environments

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(2), P. 991 - 1009

Published: Jan. 3, 2024

Micro- and nanoplastics (MNPs) are attracting increasing attention due to their persistence potential ecological risks. This review critically summarizes the effects of photo-oxidation on physical, chemical, biological behaviors MNPs in aquatic terrestrial environments. The core this paper explores how photo-oxidation-induced surface property changes affect adsorption toward contaminants, stability mobility water porous media, as well transport pollutants such organic (OPs) heavy metals (HMs). It then reviews photochemical processes with coexisting constituents, highlighting critical factors affecting MNPs, contribution phototransformation other contaminants. distinct mechanism aged pointed out, terms toxicity organisms, biofilm formation, planktonic microbial growth, soil sediment community function. Furthermore, research gaps perspectives put forward, regarding underlying interaction mechanisms natural constituents under conditions, combined fate microbiological effect photoaged especially biotransformation pollutants.

Polyethylene microplastics alter soil microbial community assembly and ecosystem multifunctionality

Environment International, Journal Year: 2023, Volume and Issue: 183, P. 108360 - 108360

Published: Nov. 30, 2023

Although pervasive microplastics (MPs) pollution in terrestrial ecosystems invites increasing concern, impact of MPs on soil microbial community assembly, and ecosystem functions multifunctionality received relatively little attention. Here, we manipulated a mesocosm experiment to investigate how polyethylene (PE MPs; 0, 1%, 5%, w/w) influence plant production, quality, diversity enzymology carbon (C), nitrogen (N) phosphorus (P) cycling, maize–soil continuum. Results showed that PE exerted negligible effect biomass (dry weight). The 5% caused declines the availability water, C P, whereas enhanced pH storage. activity C-cycling enzymes (α/β-1, 4-glucosidase, β-D-cellobiohydrolase) was promoted by 1% MPs, while β-1, 4-glucosidase inhibited MPs. reduced N-cycling (protease urease), increased P-cycling enzyme (alkaline phosphatase). shifted composition, number specialist species, stability networks resistance. altered with concentration decreasing dispersal limitation proportion (from 13.66 9.96%). Overall, improved concentration, α/β-1, urease, protease, ammonium-N content were most important predictors multifunctionality. These results underscore can alter assembly multifunctionality, thus development implement scalable solutions controlling become increasingly imperative sustainable agricultural production.
