Nitrate and nitrite levels in mineral water supplies are important indicators of water quality; Therefore, The aim of this study was to determine the amount of nitrite and nitrate in bottled mineral water available in the city of Babol.
Materials and Methods: This cross –sectional  study was the second half of 2015 of 27 bottled mineral waters recognized brand available in the city of Babol, just random two samples of each brand were collected and sent to the laboratory and  were analyzed by Spectrophotometer DR2000.
Results: The results showed that samples to be analyzed as nitrate the range of 1 to 29/7 and nitrite concentrations in range of 0/003 to 0/05 mg were reported. Brands S5 and S4 have the highest and lowest levels of nitrate and samples S5 and S15 was the highest and the lowest nitrite. Also significant differences was observed between test results with sample labels (p <0.05).

              Conclusion: All brands were marked with the national standard and Due to lack of compatibility with labels of samples analyzed parameters is                  required Endorsing organizations, constant monitoring of the production process and product quality monitoring and factory manufacturers                       Required to comply with all standards, labeling and registration are complete and consistent with real water samples
