Foodstuffs. Determination of hydride-reactive arsenic compounds in rice by atomic absorption spectrometry (Hydride-AAS) following acid extraction Ingestion-build-181247 BS 148 specifies requirements for1 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.
