A Mobile Ambient Laboratory (MAL) was placed at a residence in a community with two swine‐barn emission sites and one land application area to observe real‐time atmospheric stability, ammonia (NH3) and hydrogen sulfide (H2S) concentrations surrounding and within the residence during a 12‐week period. It was found that the concentrations and durations of NH3 and H2S measured in the ambient air surrounding the residence were far below recommended Minimum Risk Levels published by the U.S. Department of Health and Human Service’s, Agency for Toxic Substances and Disease Registry, for the protection of sensitive populations.
