Data on fluoride concentration level in villages of Asara (Alborz, Iran) and daily fluoride intake based on drinking water consumption.

In the present data article, fluoride concentration levels of drinking water (with spring or groundwater sources) in 10 villages of Asara area located in Alborz province were determined by the standard SPADNS method using a spectrophotometer (DR/2000 Spectrophotometer, USA). Daily fluoride intakes were also calculated based on daily drinking water consumption. The fluoride content were compared with EPA and WHO guidelines for drinking water.

Value of the data

Data can be used as a base-line data for concentration levels of the fluoride in spring and groundwater.

The data shown here will be informative for health policy makers by assigning interception actions against adverse health effects of fluoride with considering fluoride intake by drinking water and food.

Data shown here may serve as benchmarks for other groups working in the field of water, food, and toxicology to compute organic and inorganic daily intakes by drinking water as well as food consumption.

Data

In the Asara area of Alborz province the concentration levels of fluoride in their drinking water sources (spring and groundwater) ranged from 0.1–3.19 mg/L (Mean 0.763). As seen in Table 1, it shows that the average daily intakes of fluoride based on 2 liter daily drinking water consumption [1] reached 1.52 with a range of 1.02–2.7 mg/day. As shown in Table 1, the mean concentration levels of fluoride in drinking water of all villages were below than the EPA, and WHO drinking water guidelines.

Experimental design, materials and methods

Study area description

Ten villages of Asara (Alborz, Iran) were selected as sampling points including Sorkhedar, Sarvedar, Khor, Kondor, Moroud, Nashtroud, Abharak, Shahrestanak, Rey Zamin, and Koshke Bala (Fig. 1).

Sample collection and analytical procedures

Sixty samples were collected from 10 villages (6 samples from each village) of the Asara area of Alborz province. Water samples were collected by using 200 mL polyethylene bottles that were washed three times with deionized water; prior to collecting each sample, then bottles were labeled with the sample number and location for identification. After transferring to the laboratory, all samples were stored in a dark place at room temperature in polyethylene containers until the fluoride analysis was made by the standard SPADNS method [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16] using a Spectrophotometer (DR/2000 Spectrophotometer, USA). The concentration levels of fluoride in waters were compared with EPA and WHO guidelines for drinking water. Eventually daily fluoride intakes were estimated based on 2 l daily drinking water consumption and concentration levels of fluoride in waters.
