“…Nonetheless, according to a study of the ambient odorant emissions from a piggery facility, ammonia was identified as predominant component (up to 16.0 ppm) in hog barn and slurry treatment facilities. [14] In contrast, some of our target compounds were not detected in all six types of samples such as isobutyl alcohol, formaldehyde, benzaldehyde, crotonaldehyde, and acetic acid. Likewise trace amounts of detection were made for a few species (propionaldehyde, propionic acid, butyl acetate, and acrolein, although they only occurred in slurry samples).…”

“…[14] Thus, the characteristics of the odor substances determined from this flux measurement system can be compared with those of ambient air samples to precisely describe the effects of the different treatment methods. In addition, the odor removal efficiency (RE) with different treatment processing approaches was evaluated based on the odor intensities of odorants released from slurry samples.…”

“…According to a study of the odor characteristics of ambient air in a piggery facility, [14] the major odorants in ambient air samples from all treatment facilities were seen as VFAs, ammonia, p-cresol, and trimethylamine. As a result, most major odorants were found to contribute to odor emission, as their liquid phase slurries were converted into the gas phase.…”

“…An investigation of odorant distribution in ambient air samples in a hogpen facility was conducted in our previous study. [14] The present study was devoted to measure the emission patterns of odorants released directly from slurry samples in association with different treatment methods for odor reduction. Their emission rates were first measured by laboratory flux chamber systems and evaluated to assess odor strength in various respects.…”

The characteristics of malodor released from piggery excreta samples were investigated by measuring their emission concentrations both before and after such treatments as composting or aeration from field sites. These samples were then collected from field sites and brought into the lab for analysis with the aid of the dynamic flux chamber method. The dominating compounds in the emissions were reduced sulfur compounds, phenol, and indole. The results were examined in terms of two key odor indices: odor intensity (OI) and odor activity values (OAVs), after being grouped by some criteria. When the odor contribution in the composting facility was assessed by the OAV value, methanethiol (53.1%), trimethylamine (TMA) (25.5%), and skatole (10.1%) were dominant in the pretreatment facilities, while skatole (64.7%) and p-cresol (27.9%) in the post-treatment specimens. Likewise, in the liquid treatment facility, hydrogen sulfide (47.4%), p-cresol (26.9%), and skatole (20.2%) were dominant in the pretreatment, while only p-cresol (73.6%) in the post-treatment. In comparison to the composting facility, the liquid treatment facility proved to be more efficient in the treatment of diverse hog-barn-related odorants.
