개요
Livestock odor is comprised of mixed type of odorous compounds. Among these, ammonia (NH3) and hydrogen sulfide (H2S) are the two known majorodor causing substances. Because high odor concentration reduces productivity of livestock and causes damage to the surrounding communities,quantitative analysis is needed to manage the odor inside and outside the livestock facilities. It is also necessary to evaluate odor dispersion accordingto the distance between the receptors taking into account the influence of odor source and weather condition. Therefore, in this study, we tried toevaluate the internal environment and odor dispersion from experimental pig house considering weather conditions. An experimental farm wasspecifically selected to eliminate the interference of odors generated by adjacent farms. NH3 and complex odor were quantitatively analyzed using agas detector and air dilution sensory method. The concentration of NH3 and complex odor in pig house showed a distinct concentration differenceaccording to the cleaning and ventilation conditions. NH3 concentration and complex odor was lower than emission standard in the pig house and atthe site boundary. The average NH3 concentration (P1∼P3) and the NH3 concentration at the site boundary (S1) were strongly correlated with R=0.77. While the correlation for complex odor inside and at the site boundary had R=0.52. The correlation coefficient between NH3 and the complex odorwas 0.80.
