Abstract
Emissions of atmospheric ammonia≠nitrogen (NH3≠N, where NH3≠N ľ (14
17)NH3) and hydrogen sulfide (H2S) were
measured from a finishing swine confinement house at a commercial pig farm in eastern North Carolina. Continuous
simultaneous NH3≠N and H2S emissions were made for $1-week period during four different seasons. The number of pigs
contained in the house varied from $850 to 900 with average weights ranging from $38 to 88 kg. Average NH3≠N
concentrations were highest during the winter and spring sampling periods, 8.9174.61 and 8.4472.40 ppm, respectively,
and lower during the summer and fall, 2.4571.14 and 4.2770.71 ppm, respectively. Measured average H2S concentrations
were 6737282, 4297223, 47718, and 304788 ppb during winter, spring, summer, and fall, respectively. Generally, the
