Industry study looks at indoor air quality near hog lots

IOWA - An industry-funded study says the effect hog confinements have on indoor air quality is sometimes less than that of a cat's litter box, smoking inside or household cleaners.

Environmental groups quickly criticized the study. It was paid for, in part, by the National Pork Board, and has not yet undergone peer review.

The 16-month study is called the Air Emissions Monitoring Protocol project. It was conducted by Steven Hoff, a professor at Iowa State University's Department of Agricultural and Biosystems Engineering.

He studied five residences, and their levels of gases including hydrogen sulfide and ammonia.

He says the residence with the highest indoor ammonia concentration housed a smoker and indoor cats. The next highest reading also came from a home with cats.
