بررسی کیفیت دو برند آب معدنی تولید شده از چشمه بهرغان سپیدان فارس.

Nowadays, the consumption of bottled mineral waters is widespread in society, so awareness of its quality is essential to maintain public health. The aim of this study was to investigate the physicochemical quality of two brands of mineral water M and S bottled from the same origin and 9 factors of nitrite, nitrate, magnesium, calcium, chlorine, total dissolved solids, fluoride, total hardness and pH. One sample t-test, Independent sample t- test and Pearson correlation matrix were used to analyze the data.The results of this study showed that in both brands the mean amount of all measured factors (exception of magnesium and fluoride) were within the standard range.There were also significant differences between the measured values and the values inferred from the bottle labels (exception of pH of M brand and TH of both brands).On the other hand, with a strong positive correlation between pH and Mg of S brand and a strong negative correlation between pH and F of M brand and according to the out of standard amount of these two parameters, increasing the pH can have adverse effects on water quality of both brands.
