Is refilling water bottles bad for you?
Several articles claim that the 'chemical leaching' from reusable clear plastic water bottles leads to toxins in the water, not even just when left in the sun.
In 1998, Dr. Patricia Hunt of Case Western University in Ohio discovered that one of the components of Lexan polycarbonate resin--bisphenol-A (BPA)--can leach into water from water bottles. BPA is a potent hormone disruptor. It can impair the reproductive organs and have adverse effects on breast tissue and prostate development.
Chemical leaching is another pertinent problem in reusable bottles because it poses a significant risk to the drinker’s health. Bisphenol A, more commonly known as BPA, is a hotly controversial molecule that has been implicated in several disorders, like heart disease, diabetes, sterility and altered childhood development. [...] BPA isn’t the only chemical that has been recently investigated. Environmental Health Perspectives published a study earlier this year examining chemical leaching in BPA-free products, concentrating on baby bottles and water bottles. The researchers discovered that, despite not containing any BPA, these products still leach chemicals that mimic estrogen.
If plastic bottles are so detrimental to our health, wouldn't we have seen major signs since it is so widely used?
Is this supposed chemical leaching actually harmful?
