Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the mucous membranes of the
respiratory tract. May be absorbed from the mucous membranes, and
depending on the amount of exposure could result
in the development of nausea, vomiting, diarrhea, drowsiness, rash,
headache, fall in body temperature, low blood
pressure, renal injury, cyanosis, coma, and death.
Ingestion:
Symptoms parallel absorption via inhalation.
Adult fatal dose reported at 5 to > 30 grams.
Skin Contact:
Causes skin irritation. Not significantly
absorbed through the intact skin. Readily absorbed through damaged or burned
skin. Symptoms of skin absorption parallel
inhalation and ingestion.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
Prolonged absorption causes weight loss,
vomiting, diarrhea, skin rash, convulsions and anemia. Liver and particularly
the
kidneys may be susceptible. Studies of dogs and
rats have shown that infertility and damage to testes can result from
acute or chronic ingestion of boric acid.
Evidence of toxic effects on the human reproductive system is inadequate.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye
problems, or impaired liver, kidney or respiratory function may be more
susceptible to the effects of the substance.
