Summary
This narrative review examines the ecotoxicological behaviour and impacts of silver nanoparticles (AgNPs) introduced to agricultural soil, particularly through sewage sludge amendments. The authors synthesise findings on AgNP effects across soil microorganisms, plant physiology and animal health, as suggested by literature published through 2019. The review addresses transformation pathways of AgNPs in soil environments and their bioavailability to different organisms, contributing to understanding of nanotechnology risks in soil-based food systems.
UK applicability
Relevant to UK agricultural policy on sewage sludge use in farming, particularly regulations governing biosolids application to land. Findings inform risk assessment frameworks for emerging contaminants in soil under UK and EU environmental protection standards.
Key measures
Ecotoxicological endpoints across microbiota, plant growth/physiology, and animal health; pathways of AgNP transformation and bioavailability in soil systems
Outcomes reported
This review synthesises evidence on the ecotoxicological impacts of silver nanoparticles (AgNPs) and their derivatives when introduced to soil, with or without sewage sludge amendment. It examines effects across microorganisms, plants and animals.
