SIGNS AND SYMPTOMS OF EXPOSURE
Chronic copper poisoning is typified by hepatic cirrhosis, brain
damage and demyelination, kidney defects, and copper deposition
in the cornea as exemplified by humans with Wilson's disease. It
has also been reported that copper poisoning has lead to
hemolytic anemia and accelerates arteriosclerosis.
ROUTE OF EXPOSURE
Skin Contact: May cause skin irritation.
Skin Absorption: May be harmful if absorbed through the skin.
Eye Contact: May cause eye irritation.
Inhalation: May be harmful if inhaled. Material may be
irritating to mucous membranes and upper respiratory tract.
Ingestion: Harmful if swallowed.
