Nalgene danger overstated?

Recently, there has been quite a bit of concern that a chemical in the polycarbonate (hard-plastic) used in Nalgene bottles (among other things) poses a serious health threat. Exposure in the womb of the chemical Bisphenol A is purportedly found to raise the risk of certain cancers, hamper fertility and could contribute to childhood behavioral problems such as hyperactivity. This is extremely troubling to those who own, and frequently use, a polycarbonate water bottle. The term Nalgene is used in the same way Kleenex is, just to describe the item, not the brand. This means that regardless of whether you have an off brand polycarbonate water bottle, the risk remains. There is supposedly a number in the recyclable symbol on the bottom of these bottles, but my water bottle has no such number. Also, the water bottles they were passing out for Earth Day in front of Stauffer Flint, have no number either. I believe the numbers that indicate Bisphenol A are 6 and 7, but I might be wrong about that. However, is Bisphenol A as big of a threat as it seems? In 2004, the Center for Disease Control and Prevention found that ninety-five percent of Americans had Bisphenol A in their urine. This is not shocking to the plastic industry, as they openly admit that Bisphenol A seeps into the water and food (it is also commonly found in canned and bottled foods). They say that to incur health risks, 1,300 pounds of the food/water found in these bottles would have to be ingested daily. Not weekly, not monthly, not over a lifetime... daily. Think these numbers might be biased? They aren't set forth by the plastics industry, they're set forth by the EPA. So for everyone who just put their Nalgene away after hearing the risks, don't throw that bottle away just yet. Unless you're drinking 650 bottles a day.
