Rice grain contaminated with toxic metals : Rice is one of the world's most important staple foods, feeding more than half the global population. But the soil where it grows can also expose the crop to arsenic, cadmium and mercury, three toxic metals that can make their way into the rice grain, as per a report.
Researchers at Colorado State University are proposing a different way to tackle the problem: change the chemistry of the soil so the toxic metals become immobilized and are less likely to be taken up by rice plants.
