A potentially deadly toxin is being absorbed into bottled mineral water from their plastic containers. And the longer the water is stored, the levels of poison increase, research reveals. As the sell-by date on many bottled waters is up to two years, scientists have now called for extensive further studies.
The research by world expert Dr William Shotyk - who has vowed never to drink bottled water again - will be published in the Royal Society of Chemistry's journal next month. It is sure to revive concerns about the safety of bottled water, the world's fastest-growing drinks industry, worth £1.2billion a year.
The tests found traces of antimony, a chemical used in the making of polyethylene terephthalate (PET) bottles, used by most mineral-water sellers.
Small doses of antimony can make you feel ill and depressed. Larger quantities can cause violent vomiting and even death. The study stressed that amounts of antimony were well below official recommended levels. But it also discovered that the levels almost doubled when the bottles were stored for three months.
Professor Shotyk, of Heidelberg University in Germany, said: "I don't want to shock people but here's what I know: Antimony is being continuously released into bottled drinking water. The water in PET bottles is contaminated."
