Abstract
Cadmium is a potentially toxic heavy metal with no known
benefit to humans. Plant foods are the predominant sources of Cd in
human diets. In this study, wheat and rice collected from different
farmers from the state of Haryana were analyzed for Cd content.
Processing of wheat samples by washing and milling to flour was done
and the rice samples were milled and polished. Cd and Ni contents of
grains were analyzed using Atomic Adsorption Spectrophotometer after
diacid digestion with nitric-perchloric acid mixture. Cd was not
detectable in any of the wheat samples except four from Khungai
(Jhajjar), Sukara Khara (Sirsa), Panda (Sonipat) and Harsona
(Sonipat) villages. It was not detectable in any of the rice samples. Ni
was present in most of the wheat and rice sample analyzed.
