Since the body's greatest need for fluoride should be supplied through drinking water, determination of the amount of fluoride in drinking water has great importance. The aim of this study was to measure the concentrations of fluoride in sources of drinking water in urban and rural areas of Neyshabur in 2017 and compare it with existing standards. Materials and Methods:This descriptive cross-sectional was conducted on urban and rural drinking water sources in Neyshabur in 2017. A total of 100 water samples were randomly collected from different sources in Neyshabur. The collected samples were then transferred to the Neyshabur Water and Wastewater Laboratory and the proportion of fluoride ion was measuredusing a spectrophotometer DR 2000 at 580 nm. Results:The average concentration of fluoride in rural resources was obtained0.567± 0.12 mg/lin wells and 0.69 ± 0.13 mg/lin springs. The average co...

Corrosion is a physical and chemical reaction between materials and the surrounding environment, ... more Corrosion is a physical and chemical reaction between materials and the surrounding environment, which causes changes in the properties of the material and may lead to the financial loss of pipes, as well as other transmission and distribution facilities. In addition, corrosion may be associated with the entry of heavy metals into water sources, threatening the health of the users. The present study aimed to evaluate the corrosion and scaling potential of the drinking water sources in Neyshabur city, Iran in 2017. This descriptive, cross-sectional study was conducted on the water sources in Neyshabur city. In total, 50 samples were randomly selected from the water distribution network to evaluate the corrosion and scaling potential based on the Langelier, Ryzner, aggressive, and Pokurious indices. The mean values obtained for the Langelier, Ryzner, Aggressive, and Pokurious indices in the samples collected from the distribution network were -0.91, 9.58, 11.69, and 8.57, respectively...

In the first and end year of the study period, the Mean±SD of total hardness (as calcium carbonate, mg/l), electrical conductivity (as micromhos/cm) and total dissolved solid in the first and end year of the study period were 192.69±56.83, 235.25±84.73 and 606.21±194.69, 744.55±288.52 and 348.79±106.81, 464.71±183.52 respectively. On the basis of Pearson correlation coefficient, the ascending trend of some parameters concentration with time was significant at the level of 95% of confidence limits (α ≤ 0.05).

In general, 30 samples were randomly selected from Mashhad markets. Analysis of variance (ANOVA) and t test were used to compare color and price variables. Based on the results, the mean concentrations of studied elements were as follows: Cd (ND-0.52 µg/g), Cr (0.25-76.35 µg/g), Ni (ND-20.12 µg/g), Zn (ND-224.22 µg/g), Pb (ND-44.77 µg/g), and Hg (ND-0.32 µg/g). The presence of toxic metals in the samples, and on the other hand, continuous use and unintended ingestion of these metals can lead to their biological accumulation in the human body, thereby causing the development of different diseases. Hence, it deems necessary to apply suitable actions for the improvement of quality control over these products.
