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:
Inorganic phosphorus compounds may cause irritation and hemorrhages in
the stomach as well as liver and kidney damage. Bone structure may be
attacked, especially the jaw and teeth.
Subacute to chronic toxicity:
Chromium powder, chromium (II) and chromium (III) compounds may cause
nausea, diarrhea, vomiting, skin and eye irritation and pneumoconiosis.
Although less likely than Cr(VI) compounds, the NTP considers all
chromium to be potentially carcinogenic.
Additional toxicological information:
To the best of our knowledge the acute and chronic toxicity of this
substance is not fully known.
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.
