Time-dependent effects of microplastics on soil bacteriome
Researchers studied how six common types of microplastics affect soil bacteria over time at realistic contamination levels. The effects were slow to appear due to the chemical stability of plastics, but over time, microplastics altered bacterial community structure and soil functions in ways that differed by plastic type. This matters because changes to soil bacteria can affect nutrient cycling and crop health, with potential downstream effects on food quality.

Polyethylene microplastics distinctly affect soil microbial community and carbon and nitrogen cycling during plant litter decomposition
Researchers measured how polyethylene microplastics affect soil microbial communities and carbon cycling in agricultural soils, finding that microplastic addition shifted microbial diversity and suppressed key carbon mineralization processes. The results suggest microplastic accumulation in farmland could impair soil carbon storage.
Microplastics Trigger Soil Dissolved Organic Carbon and Nutrient Turnover by Strengthening Microbial Network Connectivity and Cross-Trophic Interactions
This study found that polyethylene and PVC microplastics in agricultural soil significantly altered the microbial communities responsible for breaking down organic carbon and recycling nutrients. The microplastics strengthened connections between bacteria, fungi, and other microorganisms in ways that accelerated carbon and nutrient turnover. These changes to fundamental soil processes could affect crop nutrition and long-term soil health on farms contaminated with microplastics.
Aging Dynamics of Polyvinyl Chloride Microplastics in Three Soils with Different Properties
Researchers tracked how PVC microplastics age and degrade over 12 months in three different soil types. They found that soil properties significantly influenced the aging process, with sandy soil promoting more surface oxidation and silty clay causing greater physical fragmentation into smaller particles. The study reveals that microplastics do not remain static in soil but undergo continuous chemical and physical changes that may affect their environmental impact over time.
Polyethylene and polyvinyl chloride microplastics promote soil nitrification and alter the composition of key nitrogen functional bacterial groups
Researchers found that polyethylene and PVC microplastics in soil increased nitrification (a key step in the nitrogen cycle) and changed the composition of nitrogen-processing bacteria. These changes could affect soil fertility and the availability of nutrients for crops. The study highlights how microplastic contamination in agricultural soil may have hidden effects on food production by altering fundamental soil processes.
