Abstract : Inorganic arsenic (As) is a chronic, non-threshold carcinogen. Rice grain and rice-based products can be the major source of Asi for many subpopulations. Present study has been evaluated the As concentration in rice grains from Ambagarh Chowki, India. Twenty two village grown rice samples were collected and Arsenic species including As(III), As(V), MMA and DMA were separated and determined by ICP-MS method. The mean concentration of total arsenic in rice samples was 101.2 ± 57.2 μg/kg. The dominant species detected in rice samples was As(III), following DMA, As(V) and MMA. The Pearson's correlation analysis indicated significant positive relationships between As(III) and total arsenic (r = 0.923, p < 0.01), and DMA and total arsenic (r = 0.811, p < 0.01). However, the percentage of As(III) decreased with the total arsenic concentration in rice (r = − 0.115, p < 0.01). High levels of the arsenic in rice grains were observed in west part of Ambagarh Chowki regions associated with mining leakage activities. The cancer risk and hazard quotient were employed to estimate the potential human health risk. The results suggested great carcinogenic risk and high potential non-carcinogenic risk to people. Keywords - Arsenic; Rice grain,mining leakage, cancer risk, carcinogenic risk
