“…Considering the results of arsenic concentration in drinking water of the rural population, it is obvious that the major exposure with arsenic in drinking water is related to the region of Kahak County (mean value of > 10 µg/L), which is much higher than the Iranian National drinking water standard and WHO guidance (1). Therefore, the exposure risk assessment was applied for the region of Kahak County.…”

“…These skin lesions generally develop within 5 -10 years after the initial exposure, although shorter latencies have been reported. Many other signs and symptoms have also been noted such as chronic cough, crepitation's in the lungs, diabetes mellitus, hypertension, and weakness (1,6).…”

“…High concentration of As and the physico-chemical parameters in groundwater in rural drinking water in Qom province has been previously reported. Mining activity and geology of the study area including rural county of Qom province and possible leaching of As in ground water has an important factor in the health of inhabitants (1,2). The present study addresses these through a human health risk assessment in the rural of Qom province for exposure by arsenic in drinking water.…”

“…Arsenic (As) is a toxic element, which is found naturally in water sources, soil, and sediments (1,2). The nature of the soil parent material appears to be the main factor determining the As concentration in soils, although due to its low supergene mobility, the soils are slightly enriched in As compared with their soil parent rocks (3,4).…”

“…It is estimated that 200 million people throughout the world are exposed to arsenic in drinking water that exceed the recommended limit of 10 µg/L as set out in the guidelines of the world health organization (WHO) (1). Arsenic (As) is a toxic element, which is found naturally in water sources, soil, and sediments (1,2).…”

Arsenic is a toxic element, which is found naturally in water sources. Due to its high toxicity it has become a serious problem in drinking water sources and also affects the health of communities. Therefore, in the present study, risk estimation and the probability of adverse health effects of exposure to arsenic from drinking water was evaluated in the rural areas of Qom province. Water samples were taken from 44 rural areas with regard to the number of rural areas and also the type of water distribution systems. The intensity, duration and frequency of exposure to arsenic in drinking water were determined. Then the hazard quotient and cancer risks ware calculated. Results showed that more than 16% of the rural population was exposed to arsenic with level above 10 µg/L in the rural regions of Kahak County (10 ± 6.29 µg/L). Results of risk assessment showed that hazard quotient (HQ) were 1.7 and 2, while the cancer risk (CR) were 76 × 10 -5 and 42 × 10 -4 for 2 groups of age 1 and 2, respectively. The results indicated that the hazard quotient is higher than 1 (HQ > 1) for group 1 and group 2. For carcinogenic effects, the study indicated that the population in the Kahak region are exposed to arsenic in drinking water with the concentration of > 10 µg/L and they are at a very high risk for cancer, due to the fact that the cancer risk for the 2 groups are more than 7.6 and 42 times the environmental protection agency (EPA) criteria, respectively. Therefore it is recommended that at first, the source and water supply system in Kahak region is to be substituted with safe drinking water and to provide health facilities and screening tests for exposed populations.
