As stated by ACGIH:
The pitch of coal tar is the black or dark
brown amorphous residue that remains
after the redistillation process. The
volatiles contain a large quantity of lower
molecular weight polycyclic hydrocarbons.
As these hydrocarbons (naphthalene, fluorene,
anthracene, acridine, phenanthrene)
sublime into the air there is an increase of
benzo(a)pyrene (BaP or 3,4-benzpyrene)
and other higher weight polycyclic
hydrocarbons in the tar and in the fumes.
Polycyclic hydrocarbons, known to be carcinogenic,
are of this large molecular type.-
