Polycyclic Aromatic Hydrocarbons
Polycyclic aromatic hydrocarbons (PAHs) consist of two or more fused
aromatic rings containing only hydrogen and carbon atoms. 1-Hydroxypyrene
(1-HP) is used for biological monitoring. "This BEI [Biological Exposure
Index] is designed to assist industrial hygienists and other occupational
health professionals in controlling occupational exposure to polycyclic
aromatic hydrocarbons (PAHs) from all routes. . . . ACGIH recommends a
benchmark value of 1 ug 1-HP/L in urine be considered a postshift level
indicating occupational exposure to PAHs." [ACGIH]
Some references use the definition of "three or more" fused aromatic
rings. [Sullivan, p. 1241] This definition
excludes naphthalene and methylnaphthalenes.
