>Is there any evidence that something transfers to you if you do touch it? This is the first I am haring about something like this. I thought plastic was essentially a solid.

I recall a few years ago there were a few articles/studies saying that that BPA were in thermal paper (ie. receipt paper). I think the conclusion was that if you were picking up a few receipts per day, the amount was negligible, but if you worked in retail it might be a hazard.
