Vinyl acetate is primarily used as a monomer in the production of
polyvinyl acetate and polyvinyl alcohol. Acute (short-term)
inhalation exposure of workers to vinyl acetate has resulted in
eye irritation and upper respiratory tract irritation. Chronic
(long-term) occupational exposure did not result in any severe
adverse effects in workers; some instances of upper respiratory
tract irritation, cough, and/or hoarseness were reported. Nasal
epithelial lesions and irritation and inflammation of the
respiratory tract were observed in mice and rats chronically
exposed by inhalation. No information is available on the
reproductive, developmental, or carcinogenic effects of vinyl
acetate in humans. An increased incidence of nasal cavity tumors
has been observed in rats exposed by inhalation. In one drinking
water study, an increased incidence of tumors was reported in
rats. EPA has not classified vinyl acetate for carcinogenicity.
