11 - Toxicological Information
SIGNS AND SYMPTOMS OF EXPOSURE
Men exposed to manganese dusts showed a decrease in fertility.
Chronic manganese poisoning primarily involves the central
nervous system. Early symptoms include languor, sleepiness and
weakness in the legs. A stolid mask-like appearance of the face,
emotional disturbances such as uncontrollable laughter and a
spastic gait with tendency to fall in walking are findings in
more advanced cases. High incidence of pneumonia has been found
in workers exposed to the dust or fume of some manganese
compounds. To the best of our knowledge, the chemical, physical,
and toxicological properties have not been thoroughly
investigated.
ROUTE OF EXPOSURE
Inhalation: Material is irritating to mucous membranes and upper
respiratory tract.
Multiple Routes: Harmful if inhaled or swallowed. Causes eye and
skin irritation.
TARGET ORGAN INFORMATION
Nerves. Blood. Kidneys. Lungs.
12 - Ecological Information
No data available.
13 - Disposal Considerations
SUBSTANCE DISPOSAL
Cautiously acidify a 3% solution or a suspension of the material
to pH 2 with sulfuric acid. Gradually add a 50% excess of aqueous
sodium bisulfite with stirring at room temperature. An increase in
temperature indicates that a reaction is taking place. If no
reaction is observed on the addition of about 10% of the sodium
bisulfite solution initiate it by cautiously adding more acid. If
manganese, chromium, or molybdenum are present adjust the pH of
the solution to 7 and treat with sulfide to precipitate for burial
as hazardous waste. Destroy excess sulfide, neutralize, and flush
the solution down the drain. Observe all federal, state, and local
environmental regulations.
