New Models Predict Cadmium Accumulation in Wheat and Improve Food Safety

Wheat, in particular, tends to absorb more cadmium than rice due to its greater internal transport efficiency. In China's rice-wheat rotation systems, wheat grains often exceed the established safety limits for cadmium, despite complying with national soil quality standards. Recently, regulations imposing stricter limits for cadmium in soil have been revised, although this could lead to unnecessary costs and over-regulation. Previous predictive models have proven insufficient, failing to capture the complexity of real soil conditions. Therefore, there is an urgent need for more precise and field-validated models to ensure wheat safety without burdening producers. New Models for Predicting Cadmium Accumulation On May 14, 2025, researchers from Nanjing University and Columbia University published a study in the Eco-Environment & Health journal presenting new models for predicting cadmium accumulation in wheat grain. Using data from 311 soil and wheat samples from across China, the ...
