Just because a water bottles label says it BPA free doesn’t necessarily mean that its free and clear of harmful chemicals. It may contain BPS a nasty family member of BPA.
BPA is controversial because it exhibits hormone-like properties that raise concern about its suitability in consumer products and food containers, BPA is an industrial chemical.
Bisphenol A was discovered in 1891 by a Russian chemist named Aleksandr Dianin . In the early 1930s a British chemist Charles Edward Dodds recognized BPA as an artificial estrogen.
The first use of BPA was to enhance the growth of cattle and poultry.
Bisphenol A is a weak endocrine disruptor, which can mimic estrogen and could lead to negative health effects.
BPA has been used since the 1950s to harden polycarbonate plastics and make epoxy resin, and in the lining of food and beverage containers.
A 2008 it was found that obesity may be increased as a function of BPA exposure, and in September 2010, Canada became the first country to declare BPA a toxic substance.
Bisphenol S (BPS), the chemical now being used in place of BPA in many “BPA-free” products, may be just as harmful — if not more harmful — than BPA.
According to a 2005 study out of Japan, BPS is only slightly less potent than BPA at mimicking the female hormone estrogen in the body. Other studies have shown that BPS is far less biodegradable than BPA, and is actually the most persistent bisphenol compound among eight of the most common bisphenol compounds tested.
I think the most disturbing thing about BPS; is the fact that BPS absorbs into the skin at much higher rates than BPA. According to a study, BPS is capable of absorbing at a rate up to 1900 percent higher than BPA, which makes it potentially much more harmful than BPA at altering hormone levels. BPS is found in receipts, some recycled paper products and currency.
I personally think I’ll take the safe route and purchase a reusable porcelain water bottle!
