In the present study, we evaluated the effect of pH modulation on concentrations of odorous compounds andpollutants in pit slurry from pig operation building. A slurry sample was taken from the pit of a pig operationbuilding where 50 finishing pigs [(Landrase × Yorkshire) × Duroc] were kept. Three levels of pH (6, 8 and 10)were measured and adjusted daily during the incubation periods using chemical reagents of 1 N HCl or 3 N NaOH. Concentrations of odorous compounds and pollutants were analyzed from slurry incubated for 7 days. When thesematerial concentrations were compared with the pH 8 slurry which was the pH of pit slurry, levels of short chainfatty acids, indoles and total organic carbon were reduced 7%, 68% and 2%, respectively, in the pH 6 treatment(P<0.05). Ammonium nitrogen, phenols and total nitrogen concentrations were lower by 31%, 18% and 17%,respectively, than with the pH 10 slurry (P<0.05). When the odor contribution in pH treatments was assessedaccording to the odor activity value, it was found to be 23% lower in the pH 6 treatment compared with pH 8. The pH modulation would affect odor emissions and microbial activity from pit slurry. Although not all odorouscompounds showed the reduction effect with the same pH control, this study can be effectively used as base datawhen using additives for pH control.
