Ethylene vinyl acetate health effects.
Ethylene vinyl acetate eva is not hazardous by ingestion unless you eat an object made of eva that s big enough to cause choking or other problems in which case it would pose the same hazards as any other plastic object.
Exposure to high levels around 1 000 ppm of vinyl acetate in air for a couple of weeks caused irritation of the eyes nose throat and lungs of laboratory animals.
Like many plastics it is difficult to biodegrade.
Vinyl acetate at levels around 200 ppm caused irritation to the respiratory tract and nose when it was breathed by rats and mice for up to 2 years.
Inhalation does not pose a threat unless you actually work in a processing plant.
