- Risk assessment of rice consumption by different French populations groups.
- Rice cooking mode has a different toxicological implication for children and adults.
- Mitigate inorganic arsenic exposure related to consumption of contaminated rice.
Total (Ast), inorganic arsenic (Asi = As(III) + As(V)) and dimethylarsonic acid (DMA) were determined in 37 commercial rice samples collected in France. Ast was measured by inductively coupled plasma-mass spectrometry (ICP-MS) whereas anion-exchange chromatography - ICP-MS was used for Asi and DMA determination. Ast in raw rice varied from 0.041 to 0.535 mg kgâ1 whereas Asi varied from 0.025 mg kgâ1 (polished Basmati rice) up to 0.471 mg kgâ1 (organic rice duo). The daily intake and associated health risk for different population groups as a function of age and gender was also assessed. The intake varied between 0.002 and 0.184 μg kgâ1 body weight for Ast and 0.002 and 0.153 μg kgâ1 body weight for Asi, which do not pose a chronic toxicity risk. Organic wholegrain rice may entail a risk for children in the case of sole consumption at the expense of polished rice. The impact of rice cooking/boiling in terms of the overall toxicological risk related to As species was also investigated. Pre-rinsing and boiling the raw rice by using an excess of water is the most efficient mode to obtain a significant Asi removal and further reduction of the toxicological risk for children, particularly for white rice varieties.
