(1) High temperature: Phthalic acid is a chemical used to soften plastics and reduce brittleness, which may lead to fertility difficulties, liver diseases and increased cancer risk. When bottled water is close to a heat source, it will dissolve phthalic acid in the bottle into water.
(2) Storage mode: High temperature is not the only factor that harms bottled water. Other things you put in the storage room will also affect bottled water. Experts suggest that bottled water should not be mixed with gas fuel, pesticides or other chemicals, because these substances will at least affect the smell and taste of water. Besides, in hot summer, storing bottled water in the car is actually a potentially dangerous move. High temperature will change its chemical equilibrium, thus accelerating the dissolution of chemicals in plastics into water.
(3)PET: For the packaging of bottled water, experts issued a red warning for some special chemicals. Antimony used to make PET polyester is a potentially toxic substance. In recent years, German chemists have found that the longer bottled water is stored (whether in stores or at home), the more antimony is produced, and a large amount of antimony will cause nausea, vomiting and diarrhea.
(4) Bisphenol A: According to the research, the chemical bisphenol A (BPA) found in polycarbonate (used to make water coolers, sports drink bottles and other hard plastics, excluding PET) may cause neurological and behavioral problems in fetuses, infants and young children, and may also affect the brains of adults and the reproductive and immune systems of women.
