Medical Conditions Generally Aggravated by Exposure

Repeated or prolonged exposure not known to aggravate any medical condition Signs and Symptoms Zinc oxide dust or fumes can irritate the respiratory tract. Prolonged skin of Exposure contact can produce a severe dermatitis called oxide pox. Exposure to high levels of dust or fume can cause metallic taste, marked thirst, coughing, fatigue, weakness, muscular pain and nausea, followed by fever and chills. Severe overexposure may result in bronchitis or pneumonia with a bluish tint to the skin. Prolonged exposure can cause reversible liver enzyme abnormalities. Diarrhea, peptic ulceration and gastrointestinal hemorrhage may also occur. _________________________________________________________________________________________________
