Aim: Rice is one of the most important parts of human diet in the world, therefore it is necessary to determine its quality by measurements of hazard pollutants.

Materials and Methods: In this study, the health risk index and concentration of arsenic was calculated according to the per capita consumption of rice. Also, the risk of cancer was assessed using the risk assessment method for slope cancer.

Findings: the average concentration of iAs was 64, 80, 92, 99, 82 μg kg^-1 and tAs was 370, 269, 214, 110, and 97 μg kg^-1 for Argentina, Uruguay, USA, Iran, and India, respectively. The risk ratios for India are greater than one and indicate the potential health risk.

Conclusion: Carcinogenic risk values for total arsenic indicate that it is greater than 4X^-10 in all countries and indicates a high risk of cancer for humans. On the other hand, the risk ratio index for rice imported from India, Uruguay, and Argentina is more than one and indicates the possibility of potential risk to the consumer. Carcinogenic risk values for total arsenic indicate that, imported rice is larger than 4X^-10 and indicates a high risk of cancer in Iranian consumers. The risk ratio for rice imported from other countries is less than one and does not indicate the potential for risk to the consumer. Also, the carcinogenic risk values for the mineral arsenic show that, imported rice from other countries is less likely to indicate a risk of cancer in Iranian consumers.
