Foodstuffs. Determination of hydride-reactive arsenic compounds in rice by atomic absorption spectrometry (Hydride-AAS) following acid extraction. | Status: Confirmed, Current

1 Scope This Technical Specification describes a screening procedure for the determination of nitric-acid extractable inorganic arsenic in rice with hydride generation-AAS. The method has been developed and validated for the application of analysis in rice. It has been validated in an interlaboratory study according to ISO 5725[2] on parboiled rice and brown rice having an inorganic arsenic content of 0,092 mg/kg and 0,191 mg/kg.
