US EditionThe 'King of Poisons' Is Building up in Rice
- A study published on April 16, 2025, in Lancet Planetary Health revealed that rising temperatures and CO2 increase arsenic uptake in rice, raising health risks by 2050.
- Researchers led by Donming Wang began this decade-long study in 2014 to assess how warming climates affect arsenic levels in 28 key rice varieties across seven Asian countries.
- The team found that higher temperatures and CO2 spur root growth, which paradoxically enhances arsenic accumulation despite potential yield benefits from carbon capture.
- Under a worst-case scenario, inorganic arsenic in rice could rise by 44 percent, prompting coauthor Lewis Ziska to warn the health consequences are "enormous" due to cancer risk increases.
- This research implies urgent adaptation efforts like improved soil management and irrigation are needed alongside emissions mitigation to prevent toxic rice and increased health risks.
