11 Toxicological information
Acute toxicity:
Primary irritant effect:
on the skin: Irritant to skin and mucous membranes.
on the eye: Strong irritant with the danger of severe eye injury.
Sensitization: No sensitizing effects known.
Subacute to chronic toxicity:
Lanthanons can cause delayed blood clotting leading to hemorrhages.
Exposure may also lead to sensitivity to heat, itching, increased
awareness of odor and taste, and liver damage.
Oxalates are powerful irritants and corrosive to tissue. They have a
caustic effect on the mouth, esophagus and stomach. Readily absorbed,
they can cause severe kidney damage.
Additional toxicological information:
Danger through skin absorption.
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.
