Abstract
Emissions of atmospheric ammonia­nitrogen (NH3-N, where NH3-N ¼ (14/17)NH3) and hydrogen sulfide (H2S) from a
commercial anaerobic swine waste treatment lagoon (17,150 m2
at normal liquid level) were measured over a 1-year period.
Continuous simultaneous measurements were made at the lagoon using a dynamic flow-through chamber system for $1
week during four seasons, October­November 2004 (fall), February 2005 (winter), April 2005 (spring), and June 2005
(summer) in an effort to examine diurnal and seasonal variability, and the respective relationships of NH3-N and H2S
emissions to lagoon physicochemical properties. Continuously measured lagoon physicochemical parameters include
lagoon surface temperature and lagoon pH. Aqueous lagoon samples were collected daily and analyzed for total Kjeldahl
nitrogen (TKN), total ammoniacal nitrogen (TAN), and total sulfide concentration. TKN, TAN, and sulfide
concentrations ranged from 400­650, 360­590, and 0.1­13.0 mg LÀ1
, respectively. For NH3-N, the largest fluxes were
observed during the summer (44200 mg N mÀ2
