COPPER (II) ORTHOARSENATE ICSC: 0648
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
BLUE OR BLUISH-GREEN POWDER.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes of arsenic (see ICSC 0013). Reacts with acids releasing toxic arsine gas (see ICSC 0222).

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as As) 0.01 mg/m; A1 (confirmed human carcinogen); BEI issued; (ACGIH 2004).
MAK: Carcinogen category: 1; Germ cell mutagen group: 3A; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

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 and the aerosol is irritating to the eyes and the respiratory tract. The substance may cause effects on the central nervous system, digestive tract, circulatory system, resulting in severe haemorrhagic, losses of fluids and electrolytes, collapse, shock and death. Exposure at low level may result in death. 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 peripheral nervous system, skin, mucous membranes, and liver, resulting in neuropathy, pigmentation disorders, perforation of nasal septum, and cirrhosis. This substance is carcinogenic to humans.
PHYSICAL PROPERTIES
Solubility in water: none
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to water. It is strongly advised that this substance does not enter the environment.
NOTES
Temperature of decomposition unknown in literature. Do NOT take working clothes home. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
