11 Toxicological information
Acute toxicity:
Primary irritant effect:
on the skin: Irritant to skin and mucous membranes.
on the eye: Irritating effect.
Sensitization: No sensitizing effects known.
Subacute to chronic toxicity:
Inhalation of magnesium compounds may cause metal fume fever. Metallic
magnesium which perforates the skin may cause local lesions. Some
magnesium salts have produced muscle weakness, cardiac arrhythmias,
respiratory effects and changes in blood chemistry following ingestion.
Subacute to chronic toxicity:
Sulfides show variable toxicity. The alkaline sulfides are similar in
action to alkalies. They cause irritation of the skin and are corrosive
by ingestion. The heavy metal sulfides are generally insoluble and show
little toxic action except through the liberation of hydrogen sulfide.
Hydrogen sulfide, if generated, is toxic, a severe irritant and
flammable. Effects include conjunctivitis, headache, nausea, dizziness,
coughing, pulmonary edema and possibly death.
Additional toxicological information:
To the best of our knowledge the acute and chronic toxicity of this
substance is not fully known.
No classification data on carcinogenic properties of this material is
available from the EPA, IARC, NTP, OSHA or ACGIH.

12 Ecological information:
General notes:
Do not allow material to be released to the environment without proper
governmental permits.
