Abstract

Mutagenicity and phthalate level of bottled water are still under-investigated. Five brands of still or carbonated mineral water bottled in PET, glass, or polycarbonate bottles were kept in sunlight or darkness at ambient temperatures or 37 °C for 0, 1, or 4 months. The ultraviolet (UV)-filtering capacity of bottles was also assessed. Concentrated organic fractions were analysed using the Ames test. Diisobutylphthalate (DIBP), diethylhexylphtalate (DEHP), and dibutylphthalate (DBP) were quantified by gas chromatography. Mean values of UVA and UVB reduction by bottle walls were 17 and 70% in PET, 16 and 70% in glass, and 66 and 86% in polycarbonate, respectively. Salmonella TA100 strain proved to be more sensitive than TA98 in the Ames test, and according to the test, we isolated direct-acting mutagens. The most mutagenic samples were identified after 1 month, stored at 37 °C and in sunlight. Water stored in bisphenol A-free polycarbonate was non-mutagenic. Phthalate concentrations were low initially and then ranged between <0.026–0.16 μg/L (DIBP), <0.29–11.72 μg/L (DEHP), and <0.005–0.2 μg/L (DBP); levels were the highest also after 1 month of storage. The highest mutagenicity and phthalate levels were detected similarly after 1 month of storage in mineral water, but mainly in different samples, and we found no significant correlation between them. Levels of phthalates were independent of bottle material. To sum up, natural organics in water can be important sources of mutagenic compound and phthalate formation. However, further analytical measurements should be performed to identify and follow-up the presence of genotoxic compounds in bottled mineral waters.
