Monomeric formaldehyde (subject of this article). Trioxane is a stable cyclic trimer of formaldehyde. Paraformaldehyde is a common form of formaldehyde for industrial applications. Methanediol, the predominant species in dilute aqueous solutions of formaldehyde.

How many ppm of formaldehyde is safe for humans?

Because Patty [1963] also reported that “it has been estimated that exposure for 5 to 10 minutes to 50 to 100 ppm might cause serious injury to the lower respiratory passages in man [Kodak 1936-1960],” 30 ppm seems reasonable as the IDLH. Other animal data: RD 50 (mouse), 3.13 ppm [Alarie 1981].
