Summary
This 2020 international narrative review synthesises the mechanisms governing cadmium bioavailability and soil–plant transfer across diverse soil types, climates and crop species. The authors evaluate evidence-based agronomic mitigation strategies—including soil amendments, varietal selection and management practices—to reduce cadmium accumulation in food crops, addressing a persistent food safety challenge in intensive and developing agricultural contexts where dietary cadmium exposure poses human health risk.
UK applicability
The review's findings on soil-plant cadmium transfer and agronomic mitigation are relevant to UK arable and horticultural systems, where soil pH, organic matter content and crop selection influence cadmium uptake. UK producers and regulators may benefit from the synthesised evidence on amendment strategies and varietal selection to manage food safety compliance.
Key measures
Cadmium bioavailability; soil–plant cadmium transfer; cadmium concentration in food crops; effectiveness of agronomic mitigation interventions
Outcomes reported
The review synthesises mechanisms of cadmium bioavailability and soil–plant transfer across diverse soil types, climates and crop species. It evaluates evidence-based agronomic mitigation strategies including soil amendments, varietal selection and management practices to reduce cadmium accumulation in food crops.
