ODOR AND VOC EMISSIONS FROM SWINE MANURE STORAGES
Odor and volatile organic compounds (VOC) were measured between May and October 2000, and between April and July 2001 at three swine farms (nursery N1; 2,000-head finishing F2; 3,000-head finishing F3) in Southwest Minnesota. A wind tunnel was used for the collection of air samples on top of the basins. Results showed that odor and VOC emissions from the finishing facilities were higher than from the nursery facility, but not statistically different. Mean odor emission was about 14 OU/m2-s for the whole monitoring period. Mean total-VOC emissions were 205 μg/m2-s and 302 μg/m2-s in years 2000 and 2001, respectively. No evident correlation was found between odor and VOC emissions. Significant amounts of alkane compounds were found in air samples. There was preliminary indication that some VOC sampled with the wind tunnel could have originated as artifacts. VOC determinations from manure samples indicated the presence of the same alkane compounds in manure, but at a significantly lower concentration than in air samples, thus suggesting rapid volatilization of such compounds. Other VOC found in manure included several known odorants such as volatile fatty acids (VFA), phenol, 4- methylphenol, 4-ethylphenol, indole, and skatole. Odor and VOC emission rates from all sites were poorly correlated with most manure characteristic parameters (nutrients, solids, organic matter).
