Summary
This comprehensive review examines the fate and ecological implications of engineered nanoparticles in agricultural soils, synthesising evidence on their transformations through physical, chemical and biological pathways. The authors integrate findings on how nanoparticles alter soil microbiota, enzyme function and biogeochemical cycling, whilst advocating for green synthesis strategies and risk-mitigation approaches to support responsible implementation of nanotechnologies in sustainable agriculture.
Regional applicability
The review is a global synthesis drawing on international laboratory and field research; findings on nanoparticle soil behaviour and microbial impacts are likely transferable to United Kingdom agroecosystems, though specific regulatory and adoption pathways will depend on UK policy frameworks and agro-climatic conditions. UK practitioners should note that green synthesis and risk-mitigation approaches align with current sustainable intensification policy priorities.
Key measures
Nanoparticle transformations (physical aggregation and sorption; chemical dissolution and redox processes; biological microbial and enzymatic degradation); soil microbial biomass, diversity and enzyme activity; nutrient cycling rates; soil respiration; persistence and stability of nanoparticles in soil
Outcomes reported
The review synthesises current research on how engineered nanoparticles transform and interact within soil matrices through physical, chemical and biological pathways, and evaluates their cascading effects on soil microbial communities, enzyme activity and nutrient cycling processes.
