Data on fluoride concentration levels in cold and warm season in City area of Sistan and Baluchistan Province, Iran
Study area
description Sistan-and-Baluchistan province in South-East of Iran between the latitudes 25° 4′- 31°25′ N and Longitudes 58° 55′- 63°20′ E, encompassing an area is about 18175 km2 (Fig. 4).The area has a hot climate, and the highest and lowest air temperatures respectively are 50 °C and −7 °C, with an annual average of 25 °C. 2.2. Sample collection and analytical procedures This cross sectional study has been conducted on rural drinking water sources under supervision of department of rural water and waste water province for a year. According to standard method number 2348 Institute of Standards & Industrial Research of Iran, Sampling was carried out randomly in different seasons. The number of sampling, was variable. Samples were taken via polyethylene packaging with volume of 1 l from any source of drinking water provided for residents. Also samples were transported to the water laboratory in each city as soon as possible in a specified condition. Fluoride concentration was estimated using HACH device (spectrophotometer DR/5000 Company, USA) -Spectrophotometer (DR 5000- HACH). By SPADNS Method at wavelength of 580 nm [1–6]. Ultimately, with employing Arc GIS 9.3 software, fluoride ion dispersion at the provincial level, with using geographic coordinates (longitude and latitude regions) from collected water place, has been depicted, then description of critical points was discussed. Excel software has been used for statistical analysis of results and its comparison with national standard number 1053 Institute of Standards and Industrial Research of Iran with announcement of maximum allowable concentration of fluorides in drinking water (0.5 to 1.5 mg/l)
