Truth about Bisphenol A (BPA)

Posted by Life is Awesome Here On 12:45 PM No comments

By now most of us have heard about Bisphenol A (BPA) and it's effect on our health; but not many of us know what is BPA and the history of it. In this article we will look into the history of BPA where it came from and where it's at today. As we know the chemical is widely used in today's age, - from plastic coatings to children's teeth sealings, plastic bottles, metal can lining, water main filters, pipes, and many other products that are used daily by us. As it's use becomes more and more common it is imperative that we look into it's origins and what affects it might have on people.

Origins

BPA is not a natural occurring chemical but a rather a man made chemical that was developed for a whole different use. BPA was invented over 100 years ago in 1891, after the initial discovery of the chemical not much was known about it until 1930's. During a study when BPA was fed to ovariectomised rats the first evidence of its estrogenicity became evident. During the same era another compound was invented, DES which is even more potent than BPA, it is worth mentioning that it was later linked to reproductive cancers in girls who were born to mothers taking DES during pregnancy, in retrospect an early warning signal for the similar toxic properties confirmed for BPA many years later.

It was not until the 1940 when the chemist found a use of the chemical in plastic, with the world at war all the scientist were eager to help there country achieve victories, thus finding new uses for previous chemicals that were not in use untill that time. Between that time and today there were some EPA guidelines put in for BPA in humans, but none of them are keeping up with the studies that are done today.

In 1988 EPA had issued a safety standard of BPA in humans which was 25 times higher than harmful levels.

1999 was the year when consumer report found out that BPA leaches out from baby bottles when they are heated.

Between 2003-2006 FDA took the first curious look at the chemical, unfortunately the whole study was conducted under an administration of an BPA industry consultant. He organized group of scientists, hand picked data from different reports and presented that to FDA.

It was not until 2007 when the industry influence was revealed, with the congress investigating the conflict of interest between National Institute of Health-which was doing the investigation of BPA. The government was forced to fire them as the industry contractor but they kept all the studies which were influenced by the industry.

Between 2007 and today there were over 150 studies that link BPA to multiple disease, but the government still fails to do anything about it.

In 2009 states started putting through legislation banning BPA use in children's bottles and formula packaging. Today 20 states have ether banned or have legislation pending on banning the sale of product containing BPA. At the same time FDA has agreed to take another jab at the BPA perhaps this time with out the industry influence.

Where is it used today.

It is imperative that we all know how wide is the use of the BPA today, although we are heading in the right direction by eliminating the use of the chemical, we still have a long road in front of us. The use of BPA is found not only in polycarbonate plastics but range from the use as a fungicide, antioxidant, flame retardant, rubber chemical, and polyvinyl chloride stabilizer. It is still used as a plastic coating in children's dental procedures, as a coating in metal cans, plastic dinner utensils, and in multiple other items that we are exposed to and come in contact with on daily bases, items such as: reinforced pipes, flooring, water main filters, enamels, vanishes, adhesives, nail polish, CD's, tools, and the list can go on and on. As you can see that the use of BPA is wide spread but the most vulnerable are the children that are weaker and can't process the elevated levels of BPA, we must urge our congress, our state Representatives to step up to the plate and ban the use of BPA. Don't wait, contact the Representative in your state and voice your concern about the problem.
