eXPOSURE Assessment to Airborne Endotoxin, Dust Ammonia, Hydrogen Sulfied and Carbon Dioxide in Open Style Swine Houses

摘要

Information is limited for the exposure levels of airborne hazardous substances in swine feed buildings that re not completely enclosed. Open-style breeding, growing and finishing swine houses in six farms in subtropical Taiwan were studied for the airborne concentrations of endotoxin, dust, ammonia, hydrogen sulfide and carbon dioxide. The air in the farrowing and nursery stalls as partially enclosed was also simultaneously evaluated.
