Unless you live in downtown Beijing, it seems like minimal problem.

That said, 2 things are bothering me right now. I work as an airline pilot and my ‘office’ air is constantly being polluted by tiny doses of burnt oil. We’ve had multiple cases already of people developing neurological problems after long time exposure.

Another thing is I have to handle receipts from the onboard printer all the time. And that paper is apparently coated in PBA’s. Wearing gloves will make me look like a clown and I don’t want to have to explain myself over and over. For now I try to touch it as little as possible till I find a more suiting solution.
