TOXICOKINETICS
The toxicokinetics of formaldehyde after inhalation, oral, or dermal exposure has been reported in
several species by many investigators. The toxicokinetics in all of the animals studied is similar
across species lines. Formaldehyde is an essential metabolic intermediate in all cells. It is produced
during the normal metabolism of serine, glycine, methionine, and choline and also by the
demethylation of N-, S-, and O-methyl compounds. After oxidation of formaldehyde to formate, the
