Toxicity to Animals
Special Remarks on
May cause adverse reproductive effects and birth defects (teratogenic).
Chronic Effects on Humans
Excreted in maternal milk in human.
Special Remarks on otherAcute Potential Health Effects:
Toxic Effects on HumansSkin: May cause skin irritation. It may be absorbed through the skin.
Eyes: Dust may cause eye irritation.
Inhalation: Dust may cause respiratory tract irritation.
Ingestion: May cause gastrointestinal tract irritation. May also affect behavior (toxic psychosis), metabolism
(anorexia), and urinary system. This material is readily absorbed from the gastrointestinal tract. Ingestion of a
massive single dose is unlikely to cause adverse effects.
Chronic Potential Health Effects:
Prolonged or repeated exposure by inhalation, ingestion, or skin contact may cause allergic reaction (possible
hypersensitization).
Other symptoms of chronic overdose effects may include, acne or other skin problems, weight loss or weight
gain, hip or shoulder pain, fullness in face, fluid retention associated with sodium retention, potassium
loss,swelling of feet or lower legs, excess or abnormal thirst, menstrual irregularities, nausea, vomiting, irregular
heartbeat, muscle cramps, weakness, osteoporosis, increased susceptibility to infection, psychosis, and eye
problems. May also affect urinary system (polyuria), liver, adrenal gland.
