More cause for concern

Bisphenol A is a chemical substance used widely around this planet in food and drink packaging, as it is a common component in many widely used plastics, including those used for bottled water. It a a basic monomer used in polycarbonates, and is also utilised in polyesters and polyether ketones. At one time it was actually used as an anti-oxidant in foodstuffs, so those of us a little longer in the tooth have probably eaten it for years, because it had always been regarded as having a low acute toxicity. It is still used in the products used to line the insides of canned foods so there is still a potential direct food contamination possible from this source.

So why the concern? Again from RedOrbit, it appears that Bisphenol A mimics oestrogen, the primary female sex hormone. A quick web search finds that some research also suggests Bisphenol A is potentially carcinogenic and may be linked to breast cancer, could be a cause of lower sperm counts, and it has even been linked to Schizophrenia.

Yes, there are a lot of 'may' and 'could' words in there, but whilst the Canadian Gov appears to be doing something about it, as in a major revue of the chemical and its possible effects on humans, I'll bet our Gov does nothing for years!

Addendum:
More on this story and the effects the information has had on the plastic bottled water industry from the Financial Post.
