Why don’t you spend five minutes and look it up yourself? I am not wasting time on somebody who has made up his mind no matter what.
I already did that. And I posted links to a research paper, 3M's datasheet, and information on NIOSH testing procedures. They all contradict your statement.
Nice try at avoiding admitting that you really don't have a clue and can't post a single link to any of the "40 studies".
