Summary
This review synthesises evidence on how microplastics contamination affects soil properties, drawing on research as of 2021. The authors examine impacts on soil structure, hydrology, nutrient cycling, and microbial communities, though they note that microplastics research in soils was still relatively nascent at the time of publication. The paper identifies critical gaps in understanding long-term effects and proposes directions for future research into this emerging soil contaminant.
Regional applicability
The findings are globally relevant, as microplastics contamination is an international issue affecting soils in multiple countries including the United Kingdom. However, as a narrative review without region-specific primary data, direct applicability to UK soil management and agricultural policy depends on complementary site-specific or UK-focused empirical research.
Key measures
Soil physical properties (structure, porosity, water retention), soil chemical properties (nutrient content, pH), soil biological properties (microbial communities, enzyme activity), microplastic concentration and characteristics
Outcomes reported
The study synthesised current knowledge on how microplastics alter soil properties including structure, water retention, nutrient cycling, and microbial communities. It identified knowledge gaps and proposed future research directions for understanding microplastics' impacts on soil health and agricultural systems.
