EMERGENCY OVERVIEW
Appearance: white crystalline powder.
Warning! Causes eye, skin, and respiratory tract
irritation. Harmful if swallowed. May cause blood abnormalities. May
cause liver and kidney damage.
Target Organs: Blood, kidneys, liver,
respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May be harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed. May cause irritation of the digestive tract.
May cause liver and kidney damage.
Molybdenum toxicity in ruminants is characterized by symptoms of
copper deficiency.
Inhalation:
Causes respiratory tract irritation. May be harmful if inhaled.
Exposure may cause blood abnormalities.
In an inhalation study, rats were administered 60 ug ammonium
molybdate/ m3, 24 hours a day for 17 weeks. Changes in erythrocyte
and leukocyte cell counts were observed.
Chronic:
No information found.
Rats were fed 25 or 50 ppm of ammonium molybdate in their food for
100 days, at which time they were killed and examined. Ammonium
molybdate at 25 ppm had no effect on growth; at 50 ppm a slight
decrease in the growth rate was observed. No deaths or significant
effects on hemoglobin levels were observed at 25 or 50
Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. Get medical aid immediately. Call a poison
control center.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. Do not use mouth-to-mouth
resuscitation if victim ingested or inhaled the substance; induce
artificial respiration with the aid of a pocket mask equipped with a
one-way valve or other proper respiratory medical device.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
