Assessing Microplastic Contamination Effects on Soil Microbial Communities in Agricultural Land
This study sampled agricultural soils with varying degrees of microplastic contamination to assess effects on microbial diversity, abundance, and enzymatic activity, finding that higher microplastic concentrations reduced microbial diversity and suppressed nutrient-cycling enzyme activity.
Plasticizers determine a deeper reshape of soil virome than microplastics
Researchers compared how microplastics and the common plasticizer diethyl phthalate independently affect soil viral communities, finding that the plasticizer caused a much more dramatic shift in viral diversity than the plastic particles themselves. Diethyl phthalate exposure led to a three-fold increase in viral genetic material and triggered widespread activation of dormant viruses within soil bacteria. The findings suggest that the chemical additives leaching from plastics may pose a greater threat to soil ecosystems than the physical plastic particles.
Effect of Polyvinyl Chloride Microplastics on Bacterial Community and Nutrient Status in Two Agricultural Soils
Polyvinyl chloride microplastics at environmentally relevant concentrations did not broadly alter bacterial diversity in two agricultural soils over 35 days, but did significantly change available phosphorus levels and shifted the abundance of specific bacterial genera. The results suggest that microplastic pollution can subtly reshape nutrient cycling and microbial community composition in farmland soils.
Microplastics negatively affect soil fauna but stimulate microbial activity: insights from a field-based microplastic addition experiment
A meta-analysis of microplastic studies found that microplastics negatively affect soil fauna abundance and diversity while stimulating soil microbial activity, based on data from multiple laboratory experiments. The opposing effects on fauna and microbes suggest that microplastics can shift soil community structure in ways that alter ecosystem functions like decomposition and nutrient cycling.
Meta-analysis reveals differential impacts of microplastics on soil biota
Soil microplastic contamination ranged from 0.34 to over 410,000 items/kg across sites, and their presence significantly increased mortality rates and decreased individual numbers, diversity, and reproduction of soil organisms, though biomass was unaffected due to opposing effects on different organism groups.
A global review on the abundance and threats of microplastics in soils to terrestrial ecosystem and human health
This review examines microplastic pollution levels across agricultural, roadside, urban, and landfill soils worldwide, finding wide variation but consistent contamination. Microplastics alter soil pH, density, and water movement, disrupt microbial communities, inhibit plant growth, and affect soil animals. For humans, the concern is that microplastics in soil can enter the food chain through crops and contaminated water.
Soil microplastic characteristics and the effects on soil properties and biota: A systematic review and meta-analysis
Meta-analysis of 2,886 experimental groups found that microplastics significantly decreased soil bulk density and aggregate stability, indicating structural damage, while also reducing plant root biomass and soil phosphatase activity. Invertebrates were more sensitive to microplastics than other soil organisms, as particles can pass through nematode gut walls causing oxidative stress and altered gene expression.
Global meta-analysis reveals differential effects of microplastics on soil ecosystem
This meta-analysis pooled data from 114 studies to understand how microplastics affect soil ecosystems at different concentrations. Higher microplastic levels reduced soil organic matter and microbial activity, suggesting that increasing plastic pollution could degrade the soil that supports our food supply.
