SECTION VI - HEALTH HAZARD DATA
Molybdenum metal, powder less than 9 microns

HEALTH HAZARDS (ACUTE AND CHRONIC)

Molybdenum compounds are poison by subcutaneous and intraperitoneal routes. Molybdenum and its compounds are highly toxic based upon animal experiments. Symptoms of acute poisoning include severe gastronintestinal irritation with diarrhea, coma and deaths from heart failure. Experimental animals exposed to high levels accumulated Mo in the lungs spleen, and heart, and showed a decrease of DNA and RNA in the liver, kidneys and spleen. (Sax, Dangerous Properties of Industrial Materials, eighth edition)

INHALATION:
Acute: May cause irritation to the upper respiratory system.
Chronic: May cause pneumonoconiosis.

INGESTION:
Acute: May cause acute molybdenum poisoning.
Chronic: May cause chronic molybdenum poisoning.

SKIN:
Acute: Prolonged or repeated contact may cause irritation.
Chronic: No chronic health effects recorded.

EYE:
Acute: Prolonged or repeated contact may cause irritation.
Chronic: No chronic health effects recorded.

TARGET ORGANS: May affect the lungs, bones, spleen and heart.

CARCINOGENICITY: NTP? No       IARC Monographs? No       OSHA Regulated? No
RECOMMENDED EXPOSURE LIMITS
See "Section II"
LD 50 / LC 50
See "Other Toxicity Data"
SIGNS AND SYMPTOMS OF EXPOSURE

INHALATION: May cause a red, dry throat and coughing.

INGESTION: Acute molybdenum poisoning may cause severe gastrointestinal irritation, diarrhea, coma, and death from cardiac failure. Chronic molybdenum poisoning as seen in animals may cause: loss of weight, anorexia, anemia, deficient lactation, male sterility, osteoporosis and bone-joint abnormalities.

SKIN: May cause redness, burning, and itching.

EYE: May cause redness, burning, itching and watering.
.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE

Pre-existing lung disorders.
.
EMERGENCY AND FIRST AID PROCEDURES

INHALATION: Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and seek medical attention.

INGESTION: Give 1-2 glasses of milk or water and induce vomiting; seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person.

SKIN: Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water; seek medical attention if symptoms persist.

EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist.
