More Reasons You Should NOT Rely on Bottled Water
February 13, 2007
German researchers have found that the longer a bottle of water sits on a store shelf or in a household pantry, the higher the dose of antimony it contains. Amounts of this potentially toxic trace element were measured for 15 brands of Canadian bottled water and 48 European brands. Concentrations reached more than 100 times the average level of antimony in pristine groundwaters (2 parts per trillion).
However, the concentration was even higher after the bottles were left to sit at room temperature for six months. Antimony concentrations in the Canadian bottled waters increased by 19 percent, concentrations in the European brands increased by 90 percent.Most of the water tested was packaged in bottles made of polyethylene terephthalate (PET). Antimony trioxide is used as a catalyst in the manufacture of PET. The different concentrations of antimony in the various brands might have been caused by differing temperatures, water pHs, or exposure to sunlight.
