Summary
This review synthesises current evidence on the sources, fate, and transport of microplastics and nanoplastics in agricultural systems, tracing their movement from soil amendment practices and irrigation through to food webs and human exposure. The authors, drawing on expertise across soil science, analytical chemistry, and environmental governance, assess the biological and toxicological implications at each stage of the pathway. The paper also critically evaluates the state of national and international governance frameworks, identifying gaps and proposing directions for more effective regulatory oversight.
UK applicability
The findings are broadly applicable to UK conditions, where microplastic contamination of agricultural soils via sewage sludge (biosolids) application, mulch films, and irrigation water is an emerging regulatory concern; the governance analysis is particularly relevant given ongoing UK post-Brexit review of environmental contaminant standards.
Key measures
Microplastic and nanoplastic particle size distributions; soil contamination levels; bioaccumulation and trophic transfer rates; regulatory thresholds and policy gaps
Outcomes reported
The paper likely reviews how microplastics and nanoplastics move through agricultural soils into food webs and ultimately human bodies, examining accumulation pathways, biological uptake mechanisms, and the adequacy of existing governance frameworks to manage these contaminants.
