Toxic heavy metals contaminating one-sixth of global cropland - study
The Guardian
|April 18, 2025
About one sixth of global cropland is contaminated by toxic heavy metals, researchers have estimated, with as many as 1.4 billion people living in high-risk areas worldwide.
Approximately 14% to 17% of cropland - roughly 242m hectares (598m acres) - is contaminated by at least one toxic metal such as arsenic, cadmium, cobalt, chromium, copper, nickel or lead, at levels that exceed agricultural and human health safety thresholds.
The analysis collected data from more than 1,000 regional studies around the globe, as well as using machine learning technology.
