In the wake of the terrifying report on leaching of bisphenol A from polycarbonate baby bottles released this month (LINK) and the frenzy of media panic that ensued ( here, here and here), I am taking a deep breath and doing my homework before deciding what to do, or what to say.
My concern over our exposure to a wide range of industrial and commercial products has been growing over the past year or so, and I'm taking this opportunity to take a detailed look at what's out there, how it gets inside us and what it does once it's there.
Keep your eye on the site for the next few days, I'll let you know what we've decided to do in our house, as well as what some other options might be - and if there is cause for concern at all.

"Dr. Frederick S. vom Saal at the University of Missouri-Columbia, a leading researcher on bisphenol A,
conducted the analysis for this study. Each bottle was filled with water, sealed and allowed to sit for 24
hours. The 24-hour tests were performed on all bottles for levels of bisphenol A leaching: first at room
temperature and then in an oven at 80°C. The 80°C treatment simulates repeated washing of the bottles
(approximately 60-100 washes) and indicates how much bisphenol A would leach from a well-used bottle"

So the implied leaching that would occur in practice seemingly would involve an amount of BPA equal only to 1/60 to 1/100 of the reported amount leaching into the wash water and rinse water of your dishwasher over the course of those two cycles and from there down the drain except for scattered droplets over all your dishes amounting to a very small percentage of the total volume of contaminated water. One might expect as well that the detergent in a normal wash would discourage BPA from lingering on the bottle any other surface in the dishwasher, so that virtually all the BPA detected in the experiment would be rinsed down the drain in practice. Then we're only eating it in salmon and tuna.
