COPPER(II) SULFATE, PENTAHYDRATE ICSC: 1416
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
BLUE SOLID IN VARIOUS FORMS

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including sulfur oxides. The solution in water is a weak acid. Attacks many metals in the presence of water.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as copper) 1 mg/m as TWA; (ACGIH 2004).
MAK: (as copper) (Inhalable fraction) 0.1 mg/m; Peak limitation category: II(2); Pregnancy risk group: D; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is severely irritating to the eyes and the skin. The aerosol is irritating to the respiratory tract. Corrosive on ingestion. If ingested, the substance may cause effects on the blood, kidneys and liver, resulting in hemolytic anemia, kidney impairment and liver impairment.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Lungs may be affected by repeated or prolonged exposure to the aerosol. The substance may have effects on the liver when ingested.
PHYSICAL PROPERTIES
Melting point (decomposes): 110C
Density: 2.3 g/cm
Solubility in water, g/100 ml at 0C: 31.7
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in fish. It is strongly advised that this substance does not enter the environment.
NOTES
The apparent melting point caused by loss of crystal water is given.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
