ABSTRACT:
The drinking water and food are main pathway entry of the As in humans
and animals. Their in-takes cause diseases i.e. skin cancer, vascular disorder,
etc. A wide variety of the rice is cultivated in the central India. The field
soil and rice cultivated in the summer season at Koudikasa village, central
India were selected for the As contamination studies. The concentration (n =
20) of total- As (AsT) in the field soil, rice grain, husk, straw and root was
ranged from 44 - 270, 0.17 - 0.72, 0.40 - 1.58, 2.5 - 5.9 and 204 - 354 mg/kg
with mean value of 126 ± 28, 0.47 ± 0.07, 0.83 ± 0.15, 4.2 ± 0.5 and 276 ± 21
mg/kg, respectively. The total arsenic, monomethylarsenonate, dimethylarsinite
and inorganic As in the rice grain are quantified.
