Carcinogenic effect: none
Toxic by absorption through the peritoneum.

INHALATION

Acute exposure:
When heated: Inhalation of fumes can cause fume fever.
Symptoms:
Sweating, shivering, headache, fever, chills, thirst, muscle aches, nausea, vomiting, weakness and tiredness.
The symptoms occur 4 to 12 hours after exposure and usually last up to 24 hours.

SKIN CONTACT

No irritation of skin for short exposure.
Chronic exposure:
In cases of poor personal hygiene, occupational dermatitis (oxide pox) can occur where zinc oxide dust combines with debris and bacteria to block sweat glands on the skin.

EYE CONTACT

Acute exposure:
May cause redness and irritation.
Chronic exposure:
Repetitive of prolonged exposure to zinc oxide fumes may cause conjunctivitis.

INGESTION

Acute exposure:
The toxic dose is 2 grams/kilogram and over. At the extreme, zinc oxide can cause gastro-enteritis.
Chronic exposure:
Permeates the placenta and excreted through maternal milk.
