Chronic Effects on Humans
Acute Potential Health Effects:
Special Remarks on other
Skin: May cause mild skin irritation in sensitive individuals. Poorly absorbed through intact skin.
Toxic Effects on Humans
Eyes: May cause mild eye irritation by mechanical action.
Inhalation: May cause upper respiratory tract irritation.
Ingestion: Ingestion of large amounts of Ammonium Pentaborate may cause nausea, vomiting, diarrhea, skin rash.
Ingestion of a large amounts of borates may affect behavior/brain/Central Nervous System/nervous system
(excitement, wakefulness or depression, restlessness, lethargy, weakness, somnolence, headache, dizziness,
lightheadedness, drowsiness, nervousness, extreme irritability, delirium, altered reflexes, confusion, alteration in
conciousness (described as "clouded"), convulsions, collapse, unconsciousness, coma), cardiovascular
system(hypotension, dysrhythmia, arrythmias)
Chronic Poential Health Effects:
Skin: Prolonged or repeated skin contact may cause dermatitis, skin redness drying and peeling.
Ingestion: Borates may can accumulate in the body with repeated exposure. They can be found in high levels in the
brain and accumulate in the bone. Prolonged or repeated ingestion of large amounts of borates may cause borism.
Borism is a sign of systemic uptake of boron-containing compounds and is characterized by dry skin, skin eruptions,
eczema, and gastric disturbances such as nausea, hypermotility, vomiting, and anorexia and weight loss and cause
symptoms similar to acute ingestion.
