See Notes.

PHYSICAL
PROPERTIES

Boiling point: 399°C
Melting point: 189°C
Solubility in water: very poor
Octanol/water partition coefficient as log Pow: 5.32

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms.

N O T E S

This substance does not usually occur as a pure substance but as a component of polyaromatic hydrocarbon (PAH) mixtures. Human population studies have associated PAH's exposure with cancer and cardiovascular diseases. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Do NOT take working clothes home.
