I heard an interview with some health expert on CBC Radio yesterday talking about the dangers of ingesting chemicals transferred from plastic containers such as water bottles. Most plastic containers are labeled on the bottom with a number from 1 to 7. The good numbers are 1, 2, 4 and 5. The bad numbers are 3, 6 and 7, which are apparently full of all kinds of nasty chemicals that can cause cancer and other serious health problems.
If you look at the bottom of a Naglene bottle, for instance, you’ll find it’s made from the number 7 type plastic which contains polycarbonate, one of those bad compounds. (I’m guessing their stock has gone way down in the past couple weeks.) I don’t drink much bottled water, but I see people drinking from those Nalgene bottles all the time.
