Oh, good grief,
the Nalgene bottles I linked to are not made of Lexan! They are made from LDPE. I used Lexan bottles for over a decade.
This sounds like one of those internet scare stories. I went looking for a comment to that from a scientist. Sure enough..

I'm researching since february 2003 in the toxicology of the plastic material told above (#7) or nalgene plastic. It appeared to be that the results are unclear. When using a strong cleaning material to it, it might leach but normal dishwasher doesn't affect it in the same level. The mice case it's just a stupid example, 'cause i'm sure that scientific used hard chemicals to wash the cage and bottles.
So my suggestion,... stop smoking and keep drinking from your nalgenes!"
