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:
Acute and chronic exposure to inorganic mercury can cause salivation with
metallic taste, pain on chewing, gingevitis, colitis, stomatitis, kidney
damage, and central nervous system damage. The latter can cause tremors,
convulsive or shaking movements and psychic disturbances such as memory
loss, insomnia, loss of confidence, irritability and depression.
Excessive exposure may result in death.
Prolonged exposure to iodides may cause skin rash, running nose, headache
and irritation of the mucous membranes. In severe cases the skin may
show pimples, boils, redness, black and blue spots, hives and blisters.
Iodides are readily diffused across the placenta.
Absorption of silver compounds by ingestion, inhalation or through broken
skin can cause argyria, a permanent bluish-grey discoloration of the
skin, conjuctiva and mucous membranes.
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.
EPA-D: Not classifiable as to human carcinogenicity: inadequate human and
animal evidence of carcinogenicity or no data are available.
IARC-3: Not classifiable as to carcinogenicity to humans.
ACGIH A4: Not classifiable as a human carcinogen: Inadequate data on
which to classify the agent in terms of it's carcinogenicity in humans
and/or animals.

12 Ecological information:
Ecotoxical effects:
Remark: Very toxic for fish
General notes:
Also poisonous for fish and plankton in water bodies.
Do not allow material to be released to the environment without proper
governmental permits.
