Plastic Water Bottles
This post has nothing to do with the recent plastic scare. April 16/2008
In a world of plastic, a new frenzy has risen. We might be poisoning ourselves with our plastic containers.
Suddenly I hear people telling me to not re use my water bottles that I buy, that my Nalgene bottle is going to give me brain damage. Is this really a concern or are we getting excited about something that’s really no big deal? Let’s review both sides of this argument.
“Do not drink out of any plastic container with a recycling number other than two, four, and five” is what I heared coming out of the radio. But what about the plastic surrounding my loaf of bread? What about my cool re-useable water bottles? My Glad Cling Wrap? All these questions I have suddenly about the safety of the plastic surrounding my food. Are we to go back to paper bags and wax paper? Sure that would be much better for the environment, but highly inconvenient and I’m sure it’s not going to happen. So what is the logic behind this new scare?
It seems as though the main concern is DEHA (diethylhexyl adipate) which is used in PET plastics. There’s a problem though, many people mix that up with another acronym DEHA, also used is plastics is diethyl hydroxylamine which has nothing to do with plastic water bottles. According to the Plasticisers Information Centre , none of the above plasticisers are carcenogenic and neither are used in plastic water bottles (Although many people dissagree on that). According to this website, ploethylene terephtalate is the chemical used in water bottles. Here’s is a website backing up that claim.
Other people are concerned about the chemical bisphenol a (BPA). There have been many conerns about this chemical and breast cancer, prostate disorders, and lowered sperm count. BPA is found in many things including baby bottles, plastic food containers, and toys. This is the chemical I am mostly concerned about. It mimics estrogen and is highly unstable over time. It has been known to cause problems in animals, even when used in small amounts. click here for a detailed review of a study on BPA
There is no way to tell what is in the container you are using. Some people think that looking at the recycling number at the bottom will help (drinking out of bottles which are only numbered 2,4, or 5) City TV from Vancouver said that they’ve asked about the number and it has nothing to do with what chemicals are used in the plastic. Dr. Rolf Halden wrote a report on plastics and he says that you should be more concerned about what’s in your drinking water than what is in the plastic.
Another major concern for the re-use of plastic water bottles is that people do not properly clean them so they are becoming breeding grounds for millions of bacteria. Experts say that you should thoroughly wash them and let them completely dhttp://healthsanity.files.wordpress.com/2006/10/adkins_bottle.jpgry between each use.
So what do we take from this? How can we know what evil chemicals are leeching into our food, and into our children’s stomachs? I don’t think we can know right now. We live in a plastic world and if you want to eat then you’re going to have to succomb to the use of plastics.
