Metal Contamination Laboratory 1 article published in JoVE Environment Determination of Inorganic Arsenic in a Wide Range of Food Matrices using Hydride Generation - Atomic Absorption Spectrometry. Maria B. de la Calle1, Vicenta Devesa2, Yiannis Fiamegos1, Dinoraz Vélez2 1European Commission, Joint Research Centre, 2Metal Trace Element Laboratory, IATA-CSIC The usefulness of an analytical method to determine inorganic arsenic in a wide range of food matrices is demonstrated. The method consists of selective extraction of inorganic arsenic into chloroform with a final determination by hydride generation-atomic absorption spectrometry.
