Data on fluoride concentration levels in cold and warm season in rural area of Shout (West Azerbaijan, Iran).

The aim of this study was to determine the concentration of fluoride in drinking water, the distribution system, in 22 villages in Shout (A city in West Azerbaijan province). Sampling of springs and underground water was carried out in two warm and cold seasons. Fluoride concentration were determined through spectrophotometer with a model, DR/5000.The fluoride concentration were compared with Iranian standards and WHO guidelines for drinking water.

Value of the data

The main health outcomes of fluoride, including dental and skeletal fluorosis.

The Iranian standard of fluoride in drinking water is based on the maximum annual temperature of the area because of temperature impact on water consumption.

In cooler areas, such as West in Northern Iran, the consumption of drinking water is lower, thus higher fluoride concentrations in drinking water are required.

Fluoridation of drinking water in rural areas with less than the WHO optimum value is recommended.

Based on the data, defluoridation of drinking water could be recommended in fluorotic rural areas.

Data

Based on Table 1, the average concentration of fluoride in warm and cold seasons (in spring and groundwater) were 0.01–3 and 0.01–4 mg/l, respectively. According Iranian standard (1053IR) World Health Organization (WHO), in 57.9% and 18.2%of samples fluoride concentration in warm and cold season was less than the permissible limit respectively.

Sample collection and analytical procedures

The samples were collected from 22 points in the rural areas of Shout in the warm and cold seasons through using census method (6 samples from each village, 3 samples in the warm season and 3 samples in the cold season). Transportation (PE containers, 200 ml) and storage of samples were carried out in accordance with standard methods of water and wastewater treatment [1], [2], [3], [4], [5], [6], [7], [8]. To determine the residual fluoride concentration of spectrophotometer UV–vis DR-500 (SPAND method was used. Finally, the concentration of fluoride was compared with Iranian and international (WHO guideline)) standards [9], [10].
