You may have seen the label BPA-free advertised on various plastic products. Every time I see one of these labels, it makes me smile because I spent a whole summer doing research on BPA and polycarbonate plastic bottles.
Bisphenol A (BPA) is a chemical used to make polycarbonate plastic. Adverse effects (carcinogenic effects, neurotoxic effects-especially on the developing brain, obesity-related effects) have been observed in animals exposed to a level of BPA similar to human levels of exposure. We found that BPA migrates from polycarbonate bottles into the water they contain at a bioactive level or level where it could have estrogenic or endocrine disrupting activity.
[this is what my summer pretty much looked like]
On April 18, 2008, Nalgene officially announced that they were going to begin phasing out bottles containing BPA. This was amazing to me because in 2005, they claimed that BPA had no harmful effects and refused to change the composition of their bottles. While they still claim their bottles are safe, Nalgene said the reason for the change was consumer demand, meaning that people like you and I had an impact on the decision! I think it’s a great example of how it’s sometimes necessary to question the safety of a product, even when the FDA declares it safe. Consumer responsibility!

In honor of Nalgene’s recent choice to go BPA-free and in celebration of consumers who make a difference, I will be giving away a Nalgene 32 oz BPA-free bottle. This particular bottle supports filterforgood.com, which encourages the use of filtered water in reusable water bottles to save on landfill waste.
