Examination of atmospheric ammonia levels near hog CAFOs, homes, and schools in Eastern North Carolina

Hog concentrated animal feeding operations (CAFOs) release ammonia (NH 3) in Eastern North Carolina (NC) to the atmosphere which is potentially hazardous for nearby human populations at community locations particularly homes and schools. We present NH 3 weekly average concentrations that were collec...

Zusammenfassung:Hog concentrated animal feeding operations (CAFOs) release ammonia (NH 3) in Eastern North Carolina (NC) to the atmosphere which is potentially hazardous for nearby human populations at community locations particularly homes and schools. We present NH 3 weekly average concentrations that were collected using passive diffusion tubes from October 2003 to May 2004 (20 sites) and from July 2004 to October 2004 (23 sites) near community locations in close proximity to hog CAFOs. The data for each phase of sampling was stratified by distance from the nearest hog CAFO. The mean Phase I levels were 16, 8, 7 and 5 ppb for distances
