The next sentence in the journal article reads "However, if more than just the finger pads contact the BPA-containing paper or a hand cream enhances permeability of the skin, this margin might be smaller." The paper earlier mentions that moisture can increase uptake by a factor of 10. The TDI as it currently stands was presumably established before this research and other related research was done. You are assuming that its current level is correct, which in my opinion, isn't a very good assumption. Your analogy to water intoxication remains puzzling to me. The typical cashier or accounting clerk might reasonably touch thermal paper receipts 10 hours per day, and use hand lotion. The typical cashier would not typically drink 20 liters or more of water per day to the point of experiencing water toxicity. The point is that it is not unreasonable to voice concern over this issue.
