Microplastics (MPs) contamination presents a significant global environmental challenge, with its potential to influence soil carbon (C) dynamics being crucial aspect for understanding C changes and cycling. This meta-analysis synthesizes data from 110 peer-reviewed publications elucidate the directional, magnitude, driving effects of MPs exposure on globally. We evaluated impacts characteristics (including type, biodegradability, size, concentration), properties (initial pH organic [SOC]), experimental conditions (such as duration plant presence) various components. Key findings included promotion SOC, dissolved C, microbial biomass root following addition soils, while net photosynthetic rate was reduced. No were observed respiration shoot biomass. The study highlights that concentration, along other attributes, critically influences responses. Our results demonstrate both nature environment interact shape cycling, providing comprehensive insights guiding strategies mitigating impact MPs.

A growing number of studies have demonstrated that microplastic (MP) contamination is widespread in terrestrial ecosystems. wide array MPs made conventional, fossil-based polymers differing size and shape has been detected soils worldwide. Recently, also bioplastics found soils, but there a dearth information concerning their toxicity on soil organisms. This study aimed at exploring the potential induced by exposure for 28 days to irregular shaped differently sized (polyethylene terephthalate – PET) bioplastic (polylactic acid PLA) polymer earthworm Eisenia foetida. Two amounts (1 g 10 g/kkg soil, corresponding 0.1% 1% weight) both MP types were administered earthworms. multi-level approach was used investigate MP-induced effects sub-individual individual level. Changes activity antioxidant detoxifying enzymes, as well lipid peroxidation levels, investigated specific time-points (i.e., 7, 14, 21 days) responses. Histological analyses performed assess tissue level, while change digging considered proxy behavioral effects. Earthworms ingested polymers. PET did not induce any adverse effect none biological levels. In contrast, PLA caused modulation earthworms' oxidative status showed bell-shaped superoxide dismutase coupled with an increase glutathione peroxidase activity. However, neither damage, nor alteration occurred. These findings suggest bio-based can cause higher compared MPs.

Recent Insights into Microplastic Pollution and Its Effects on Soil Carbon: A Five-Year Ecosystem Review

Microplastics, Год журнала: 2025, Номер 4(2), С. 18 - 18

Опубликована: Апрель 14, 2025

The widespread presence of microplastics (MPs) is growing concern for both the scientific community and public. Contemporary research increasingly focuses on ecosystem transformation global climate change. We conducted a literature review, consisting 46 studies, to investigate consequences MPs’ influence carbon cycle in different soil types across various ecosystems. MPs can affect cycling compounds other biogenic elements by impacting microbiome, enzyme activity, plant growth, litter decomposition, more. majority authors report increased CO2 and/or CH4 emissions soils containing MPs. However, some studies demonstrate opposite or neutral result, outcomes differ even within single study depending type type, form, size used. Further clarification development our understanding regarding impact ecosystems remain crucial, taking into account inclusion as wide variety possible future research.
