Summary
This 2017 review synthesises contemporary understanding of cadmium transfer mechanisms from temperate agricultural soils to food crops. Drawing on expertise from Rothamsted Research and international collaborators, the paper examines how soil chemistry—particularly pH and organic matter—modulates plant cadmium uptake and human dietary exposure through crop consumption, reflecting policy concern about contaminant food safety in UK arable systems. Specific quantitative risk estimates and detailed mechanistic findings cannot be confirmed without access to the full text.
UK applicability
The paper addresses cadmium contamination in UK agricultural soils directly, as cadmium-enriched legacy phosphate fertilisers remain a concern in temperate arable systems. Findings are likely applicable to UK crop safety regulation and soil remediation policy, though local soil variability and crop type selection will influence risk magnitude.
Key measures
Cadmium bioavailability in soil; plant cadmium uptake rates; soil pH, organic matter content, and other soil chemical properties; dietary exposure pathways through crop consumption
Outcomes reported
A synthesis of mechanisms governing cadmium transfer from agricultural soils to edible crops, examining how soil properties (pH, organic matter) modulate plant cadmium uptake and subsequent human dietary exposure.
