Background: The pollution of water with heavy metals and their entering the biochemical cycle can lead to environmental degradation. Arsenic in drinking water is one of the elements whose high concentrations have adverse regulatory consequences for the health of the body. Therefore, this study was conducted to determine the health risk of arsenic in drinking water, irrigation water, and rice in Meydavood District in Khuzestan Province, Iran.Methods: Samples were collected from drinking water wells, agriculture, and rice grains cultivated in the area. After preparations, the samples were analyzed for arsenic using inductively coupled plasma mass spectrometry (ICP-MS).Findings: The results showed the mean concentration of arsenic in the drinking water, the water used for irrigation, and in the rice of Meydavood District to be 8, 12.75 mg/l, and 0.079 mg/l, respectively. Chronic daily intake (CDI) of arsenic through water and rice, for children, women, and men were calculated and were lower than the Food and Agriculture Organization (FAO) standards. However, target hazard quotient (THQ) values in the 3 groups were higher than 1, which suggests that people are exposed to significant health risks.Conclusion: In general, the THQ (>1) for residents, especially for children, due to the drinking of water and consumption of rice, falls within unsafe limits. Considering the effects that the flow variations and the length of time water stays in the well have on the concentration of arsenic, it is important to monitor water levels and discharge rates.
