- •
A mass balance based soil heavy metal accumulation model was developed.
- •
Trends of soil Cd content under five remediation scenarios was predicted.
- •
Liming reduces Cd content in rice produce but increases soil Cd in the long term.
- •
Higher inputs of Cd in the past were estimated based on retrospective simulations.
- •
Integrating remediation measures reduced Cd in both soils and rice grains.
