non-food sources of BPA

If you've read the Silent Spring Institute's new findings from their study: Food Packaging and Bisphenol A and Bis(2-Ethylhexyl) Phthalate Exposure: Findings from a Dietary Intervention, you may be wondering some of the same things I am. If BPA is metabolized in the body in 3 days, then where is the remainder of BPA left in the bodies of the test subjects coming from? 

No one is absolutely sure, but I have some ideas.


1. grocery store receipts
Did you know that most grocery store receipts are loaded with BPA? According to a study that examined BPA exposure from handling receipts, "New tests show that simple handling of receipts can transfer as much bisphenol A (BPA) though skin as humans get exposed to from canned food. The tests also found BPA on paper money, hinting that BPA is easily coming off of receipts and onto other items." So, skip the receipt - and definitely don't place receipts in bags with food items, especially those you eat raw.


2. tap water
Could there be BPA in tap water? A 2009 tap water safety survey found exactly that: "These could be leaching out of [household] plastics, even plastic pipes [used in] the treatment process." Invest in a powerful water filter if you can, and avoid filtering systems made with plastic.


3. personal care products
"There are two solvents commonly used in cosmetics and personal care products: phthalates, and Bisphenol-A. These ingredients are often hidden, remaining undisclosed on product labels." -Toxic Beauty: How Cosmetics and Personal Care Products Endanger Your Health . . . And What You Can Do about ItAnd what about natural, organic beauty products? A little better, but still a contributor. Most are packaged in plastic, which can contaminate the product and be absorbed into the system through the skin. 


4. dental sealants
Don't get me started on this one. I just had dental work done a couple months ago. I go to a "green" dentist, but am not sure if there is BPA in the dental sealant that they use. 


So, what's the bottom line? BPA and phthalates are virtually everywhere, in every product that we use. Simply reducing food packaging will not reduce your BPA levels to 0. The good news? You can do something about each item on this list to eliminate it from your environment. I've started in on most of these and will be posting my solutions as my experiment continues.
