文摘

•: Bioaccessibility of arsenic in rice, seaweed and fish occurs mainly in the stomach.
•: Arsenosugars are degraded in the gastrointestinal tract but when ingested from seaweed they remain unchanged.
•: The toxicity of arsenic in rice is increased in the gastrointestinal tract.
•: Chemical demethylation of arsenic species is likely to occur in humans.
•: A mechanism for arsenosugar degradation is suggested.
