Toxin BPA Contaminates Plastic Beverage Containers

As if the problem of chlorine, lead, pesticides, and other toxins in our municipal water is not enough, there is growing concern with the plastic containers from which we drink that water, as well as other beverages. Specifically, scientific studies indicate that most plastics leach various pollutants into the fluids stored in and dispensed from the water bottles and other containers made from those plastics.


For instance, there is a brewing controversy over one such toxic substance, bisphenol A (BPA), a chemical utilized in the manufacturing of clear, hard plastics such as those found in food-storage containers, baby bottles, and the lining of soda cans. BPA is released from such plastics when they are washed, heated, or exposed to acidic substances -- such as citrus fruit juices and soda -- and simply from the aging of the plastic. In turn, the BPA contaminates the contained food with which it comes in contact.


Health experts know that sex hormones, even in tiny amounts, can have dramatic effects upon human beings. Unfortunately, BPA imitates the sex hormone estradiol.

Estradiol is a female hormone that occurs naturally, but isn't synthetuc estradiol used in oral contraceptives known to reduce B12 (correct be if I'm wrong on this one)...


Astonishingly, these results have been known for many years. In a peer-reviewed and comprehensive study published on 13 April 2005 in Environmental Health Perspectives, Frederick S. vom Saal and Claude Hughes of the University of Missouri noted that there have been 115 published studies on the low-dose effects of BPA. Of these published studies, 94 reported deleterious effects on the mice and rats tested, while only 21 studies found no damage. It is rather telling that of the 11 studies funded by chemical companies, not one found any adverse effects from BPA. (Of course, this could just be a coincidence.) Of the studies conducted by scientists not associated with chemical manufacturers, over 90 percent discovered ill effects from BPA.

I've read about this in an article a while back, and the article referred to the fact that so many people walk about with a plastic bottle to drink from, and sometimes some of the plastic gets into the water if the bottle is re-used. It recommended only drinking from glass bottles.
