Microplastic pollution promotes soil respiration: A global‐scale meta‐analysis

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(7)

Published: July 1, 2024

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.

Concentration‐ and Size‐Dependent Influences of Microplastics on Soil Hydraulic Properties and Water Flow

European Journal of Soil Science, Journal Year: 2025, Volume and Issue: 76(1)

ABSTRACT Extensive usage of agricultural plastic film correspondingly leads to excessive residues microplastics (MPs). MP accumulation alters soil hydraulic properties and water flow. However, little is known about the combined effects concentration particle size on hydrological properties, a numerical approach for modelling infiltrated flow has not been well developed. Hence, we determined affected by established model suitable MP‐contaminated soils. Quantitative findings indicated that saturated conductivity soil–MP mixture was 10.8%–50.0% smaller than pure soil, which decreased increased with increase in size, respectively. The always had significant influences conductivity; contrast, generated under condition small size. Besides, higher or MPs led weaker water‐holding capacity, residual content 0.6% – 41.5% 0.2% 11.6%, Furthermore, presence inhibited infiltration, wetting front migration rate cumulative infiltration 7.1% 29.4% 4.7% 21.7%, respectively, Correlation analysis negatively correlated saturated/residual moisture, infiltration; addition, conductivity, compared (15.63%), (46.28%) played major role response movement changes external environment.

Micro/nanoplastics pollution poses a potential threat to soil health

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(8)

Published: Aug. 1, 2024

Abstract Micro/nanoplastic (MNP) pollution in soil ecosystems has become a growing environmental concern globally. However, the comprehensive impacts of MNPs on health have not yet been explored. We conducted hierarchical meta‐analysis over 5000 observations from 228 articles to assess broad parameters (represented by 20 indicators relevant crop growth, animal health, greenhouse gas emissions, microbial diversity, and pollutant transfer) whether depended MNP properties. found that exposure significantly inhibited biomass germination, reduced earthworm growth survival rate. Under exposure, emissions gases (CO 2 , N O, CH 4 ) were increased. caused decrease bacteria diversity. Importantly, magnitude impact soil‐based was dependent dose size; however, there is no significant difference type (biodegradable conventional MNPs). Moreover, As uptake plants, but promoted plant Cd accumulation. Using an analytical hierarchy process, we quantified negative as mean value −10.2% (−17.5% −2.57%). Overall, this analysis provides new insights for assessing potential risks ecosystem functions.
