And in 3d printing groups, it was common to hear people say "ABS smells like cancer". Sure, anecdotes aren't evidence proper, but the science certainly bears this claim.
Edit: And to add my own anecdote, I have a large format high temp printer. It is capable of printing stuff like ultem (375c tip, 220c bed). It is enclosed with a activated carbon filter/fan for airflow. But one time when printing polycarbonate, I took a .5w green laser to the print area. When it was shining near the print interface, I could see ALL SORTS of stuff being flung at high speed away from the nozzle. Lets just say I was glad I have that machine fully enclosed.
