Arsenic and Heavy Metals in Vietnamese Rice: Assessment of Human Exposure to These Elements through Rice Consumption.


ABSTRACT: In this work, twelve heavy metals and arsenic, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn, in a rice sample collected from some areas of Vietnam have been quantified and implemented by using multiple analytical platforms such as ICP-MS, AAS, and mercury analyser. Seventy rice samples collected from the Red River Delta and mining zone activity were analysed. Concentration of heavy metals and arsenic in rice was analysed after appropriated sample digestion using internal or external calibration curves. The mean concentration (mg kg-1 dried weight) of the analysed elements in rice samples decreased on the order of Mn (19.268)?>?Fe (13.624)?>?Zn (8.163)?>?Cu (3.138)?>?Ni (0.384)?>?Cr (0.296)?>?Co (0.279)?>?As (0.115)?>?Cd (0.111)?>?Pb (0.075)?>?Hg (0.007)?>?Se (
