Computer model of a Bisphenol-A molecule.

Canadians – a bunch of walking, talking BPA vessels? Apparently so. Statistics Canada recently released results from their first nationwide look into bisphenol A, and the results aren’t pretty.

According to a Globe and Mail report on the stats, 91 per cent of Canadians tested show some sort of BPA exposure, and teenagers carry most of the brunt, with their bodies often containing up to 30 per cent more BPA than the rest of the population.

When the first round of BPA warnings surfaced years ago, it looked like Canada would take a stand that could lead to the ingredient being declared a toxic chemical. And since then, while that declaration has stalled, the levels of BPA found in our bodies continues to rise.

It can seem like fear mongering, but BPA really is in a shocking amount of everyday products. CDs, tin can liners, and plastic water bottles all contain BPA. Most people get a steady BPA diet through food packaging. The big deal is that the chemical mimics estrogen — the average level of BPA in our bodies is actually close to 1,000 times the normal level of naturally occurring estrogen.

Of course, some scientists, and those who are involved in the BPA industry, say that just because something is in our body, doesn’t mean it’s causing harm. And it’s true that while we can speculate on what this added BPA might mean for us, we don’t know for a fact if it causes health problems.

But it’s concerning the ease with which we let synthetic products become a part of our diet with very few restrictions. The argument that it’s probably not causing any harm to our bodies is ridiculous — seeing as how BPA’s not a naturally occurring ingredient in our food system, we shouldn’t be ingesting it.

It’s interesting that the media also recently wondered why puberty continues to hit our adolescents earlier and earlier. If what we’re putting into our bodies as fuel isn’t natural, our bodies won’t act that way either. (Of course it hasn’t been proved if there are any links between chemicals like BPA and early puberty, though the New York Times article linked above does mention it briefly.)

The pessimist in me wonders if it’s too little too late now. We’ve been exposed to products with BPA so long that all the studies are doing is proving that our bodies are at the whim of packaging manufacturers. This is testing that shoud have been done years ago, but it’s only now that we’ll get a peek at what’s happening to us.

1. Create your own “pure” water by investing in an at-home water filtration system. Get a water-quality report from your municipality to see if there are any contaminants you need to be aware of (usually only an issue in rural settings) and to find out whether you need a point-of-entry unit that will filter all water before it’s distributed through your house, or a smaller unit that treats water once it’s out of the faucet.

2. Pick up a stainless-steel water bottle to carry that tap water in. With the safety of reusable plastic bottles in question for containing bisphenol A (BPA), a suspected hormone disruptor and carcinogen, it’s time to ditch that “indestructible” Nalgene bottle in favour of a shiny, metal version. Bring it everywhere.

3. Pass on overpriced bottled water when you’re out to eat and request a glass of free ice water instead. No need to be afraid: Canadian tap water is more rigorously screened than the bottled stuff.

4. Lobby to make tap water more convenient. Contact your city council and ask to have more drinking fountains and water spigots installed around town.

5. Create a bottled-water-free bubble at your school or office. On World Water Day in March, 2008, the Polaris Institute launched a campaign to discourage bottled water use on Canadian campuses in an attempt to reject the commodification of one of the world’s most precious resources. Visit PolarisInstitute.org for more details and talk to your powers above to create your own tap-water-only zone.

6. Donate your autograph to the cause. Head over to Article31.org and sign a petition asking the United Nations to declare access to potable water a human right.

7. Do the math. A litre of tap water in most Canadian municipalities costs less than a tenth of a cent, whereas a litre of bottled water can cost $1 or more. The switch should be a no-brainer.
