CHLORDECONE ICSC: 1432
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS

CHEMICAL DANGERS:
On combustion, forms chlorine fumes and hydrogen chloride. The substance decomposes on contact with acids producing toxic fumes.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: Carcinogen category: 3B; (DFG 2002).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body through the skin, by ingestion and by inhalation.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system and liver, resulting in impaired functions and liver impairment. The effects may be delayed.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the endocrine system. This substance is possibly carcinogenic to humans. Causes toxicity to human reproduction or development.
PHYSICAL PROPERTIES
Sublimation point: 350C (decomposes)
Solubility in water, g/100 ml at 20C: poor
Octanol/water partition coefficient as log Pow: 3.45
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish, in mammals and in milk.
NOTES
Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Consult national legislation.
