Rice feeds more than half the world, but 3 toxic metals can travel from paddy soil into its grains; researchers propose changing soil chemistry and reinforcing plant barriers to keep arsenic, cadmium and mercury out

Rice grain contaminated with toxic metals: Rice cultivation faces contamination from toxic metals like arsenic and cadmium. Researchers propose altering soil chemistry to immobilize these harmful elements. This strategy aims to prevent metals from entering the edible rice grain. The approach targets low to moderate contamination levels in rice paddies.
