Key Points

Higher ferrihydrite levels correlate with reduced inorganic arsenic in rice grains, indicating soil management impacts.
The study shows that arsenic accumulation in rice can be managed by adjusting soil properties, specifically ferrihydrite content.
Assessment involved analyzing arsenic species in rice grains sourced from varied paddy soils, highlighting significant variances.
These findings may inform agricultural practices, emphasizing the need for monitoring soil amendments to control arsenic levels.

Implication

Analysis reveals ferrihydrite levels affect inorganic arsenic species in rice grains, suggesting food safety concerns.

Abstract

Rice is consumed by ~50% of the global population, grown primarily in flooded paddy fields, and is susceptible to arsenic accumulation. Inorganic arsenic, particularly in reduced form (As(III)), is considered...
