PENTACHLOROBENZENE ICSC: 0531
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE CRYSTALS, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive fumes including hydrogen chloride.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver, resulting in liver impairment. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
PHYSICAL PROPERTIES
Boiling point: 275-277C
Melting point: 86C
Relative density (water = 1): 1.8
Solubility in water: none
Vapour pressure, Pa at 25C: about 2
Relative vapour density (air = 1): 8.6
Relative density of the vapour/air-mixture at 20C (air = 1): 1.00
Octanol/water partition coefficient as log Pow: 5.03-5.63
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish, in milk, in plants and in mammals. The substance may cause long-term effects in the aquatic environment. This substance may be hazardous to the environment; special attention should be given to its persistence in soil and its adsorption into sediments.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
