Ammonia and relate emanating from a lar dairy area

Volatilization of nitrogen from animal wastes in combined form, principally ammonia, has recently received attention because of the high concentration of large numbers of animals in some production operations. One constituent of animal waste that is a potential pollutant to surface and ground water is combined nitrogen. Small amounts of nitrogen in animal wastes are also apparently volatilized in the form of amines which are ammonia derived compounds. Amines are one group of compounds that contribute to the objectionable odors emanating from confined animal operations.
