Gases and odors from swine wastes
Raising hogs in confinement has caused concern for air quality inside and outside of buildings. Complaints and lawsuits by neighbors and urban dwellers have turned attention toward odors and methods of controlling them. Other concerns for air quality are for those who work in the buildings, and for the hogs. High levels of noxious gases in confinement buildings have caused persons to experience irritation in breathing. Also, dead hogs have been reported when noxious gas levels became critically high.
