Data on health risk assessment of fluoride in drinking water in the Khash city of Sistan and Baluchistan province, Iran.

According to studies, high concentration of fluoride in drinking water has adverse health effects such as dental and skeletal fluorosis. This data analyzes the concentrations and health risks of fluoride in 30 drinking water samples collected from 11 villages of the Khash city, Sistan and Baluchistan province in Iran. Fluoride concentration was measured using SPADNS method according to the standard method for examination of water and wastewater. Data indicated that average fluoride concentration in drinking water was 0.731 mg L-1. The mean estimated daily intake (EDI) values for fluoride in different groups of infants, children, teenagers and adults were 0.0058, 0.0414, 0.0292 and 0.0234 mg/kg, respectively. Also, risk assessment data indicated that hazard quotient (HQ) value of groundwater samples was less than one in 90% of samples in age groups of infants, children, teenagers and adults.

Data on health risk assessment to the nitrate in drinking water of rural areas in the Khash city, Iran.

The main objective of this data was determination of the nitrate concentration and its health risk assessment in the drinking water resources. In the aim of this data article a number of 30 samples of nitrate concentration in drinking water resources were collected from villages of the Khash city, Sistan and Baluchistan province, Iran. The nitrate concentration was measured using a Spectrophotometer accordance standard methods for examination of water and wastewater. Data indicated that nitrate concentration in drinking water ranged from 6 to 35 mg/L (average 16.083 mg/L). The mean EDI values for nitrate in different groups of infants, children, teenagers and adults were 0.1287, 0.9114, 0.6433 and 0.5155 mg/Kg, respectively. The findings of data showed that HQ value was less than 1 in 96% of samples in age groups of infants, children, teenagers and adults.
