Abstract

Rice is a common food in the state of Assam, and because it is grown in arsenic contaminated soil, eating it might expose people to arsenic. Standard procedures were used while analysing arsenic content in various parts of rice plant and other biochemical indicators related to arsenic stress. In descending order, the rice plant's parts that accumulate arsenic are root, straw, leaf, husk, and grain. With a reduction in the build-up of arsenic, it was observed that the catalase activity increased, although the ascorbic acid oxidase activity, hydrogen peroxide content, malondialdehyde content, and proline content all decreased. It is clear from the current study that the amount of arsenic in the rice grain (0.094 to 0.147 ppm) is below the permissible limit prescribed by FAO/WHO, but since the local population typically eats rice three times a day, which may cause bioaccumulation so efforts can be made to check arsenic in the cooked rice as well.
