Title: Arsenic in rice: Determination, bioavailability and potential toxicity

Biography

Biography: Basem Shomar

Abstract

More than 60 rice samples have been collected from the local markets of Qatar and additional 20 rice samples have been collected from the West Bengal, India. Total arsenic and other trace metals have been analyzed using ICPMS. New methods have been developed to study the bioavailability of arsenic including synthetic stomach and small intestine. Studying arsenic speciation is challenging and the study tried to use LAICPMS to address the distribution of the As within the rice grains.
The purpose of this talk is to highlight the total concentration of arsenic (and other trace elements) in rice; the bioavailability tests, the speciation and the potential toxicity.
