Fluoride (F) intake by formula-fed infants is highly variable, depending primarily on the F content of the water used to dilute the concentrated liquid or powdered infant formula products. The aim of the present study was to estimate the F intake by Iranian powdered milk-fed infants by taking account of the F content in the drinking water in different areas of Iran and the F content in the commonly used brands of powdered milk. The results showed that many infants in some regions of Iran were exposed to higher F intakes from powdered milk formula than those of other regions with a lower drinking water F level. Only in Bushehr province was the mean provincial F level in the groundwater resources higher than the WHO guideline value of 1.5 mg/L (1.86±0.86 mg/L) and the mean F intake of the powdered milk-fed infants in this province was 40–50 µg/kg body weight (bw)/day, less than the EPA’s reference dose (RfD) of 60 µg/kg bw/day. The F intake of powdered milk-fed infants in the other ar...

High concentration of Fluoride (F) in powder milk (formula-milk) can have adverse health effects on body. The fluoride concentration of powder milk was analyzed in Iran in 2010. Twelve commercial brands of highly-consumed powder milk was selected to analyze fluoride content through standard fluoride ion-selective electrode (ISC) method. Three samples with different production dates from each brand were selected. The mean (±SD) fluoride concentration in all the samples was 1.73±0.3 mg F/g. The minimum and ...

The nanophotocatalytic process using nano-structured semiconductors is one of the techniques used for the destructive oxidation of organic compounds such as dyes. The photocatalytic oxidation of Reactive Orange 16 aqueous solution, applied in the textile industry, was assessed by UV ray irradiation in the presence of TiO2 nanoparticles. It was found that the photons required for the process were completely absorbed when TiO2 concentration reached 0.4 g/L. Degradation of paint decreased with increasing TiO2 ...
