Chemical Safety
0104 BENZO(a)PYRENE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
PALE-YELLOW CRYSTALS The substance can be absorbed into the body by inhalation of its
aerosol, through the skin and by ingestion.
Chemical dangers
Inhalation risk
Reacts with strong oxidants causing fire and explosion hazard.
Evaporation at 20/C is negligible; a harmful concentration of
Occupational exposure limits airborne particles can, however, be reached quickly when
dispersed.
TLV: Exposure by all routes should be carefully controlled to levels
as low as possible A2 (suspected human carcinogen); (ACGIH
Effects of long-term or repeated exposure
2005).
MAK: Carcinogen category: 2; Germ cell mutagen group: 2; (DFG This substance is carcinogenic to humans. May cause heritable
2005). genetic damage to human germ cells. Animal tests show that this
substance possibly causes toxicity to human reproduction or
development.
PHYSICAL PROPERTIES
Boiling point: 496/C Solubility in water: none (<0.1 g/100 ml)
Melting point: 178.1/C Vapour pressure : negligible
Density: 1.4 g/cm3 Octanol/water partition coefficient as log Pow: 6.04
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish, in plants and in molluscs. The
substance may cause long-term effects in the aquatic environment.
NOTES
Do NOT take working clothes home.
Benzo(a)pyrene is present as a component of polycyclic aromatic hydrocarbons (PAHs) in the environment, usually resulting from the
incomplete combustion or pyrolysis of organic matters, especially fossil fuels and tobacco.
