Abstract

The goal of this study was to evaluate the effects of 1) soybean oil sprinkling (SOS), 2) misting of essential oils (MEO), and 3) misting of essential oils and water (MEOW) on ammonia (NH ₃), hydrogen sulflde (H ₂S), non-methane hydrocarbons (NHC), total suspended particulate (TSP), particulate matter less than ten microns diameter (PM ₁₀), and odor. Baseline emissions of each variable are also presented. Measurements recorded at 1-min intervals were taken from 8/27/02 to 7/21/03 at two fan-ventilated swine finishing barns that were flushed daily with lagoon effluent. TSP and PM ₁₀ were monitored with real-time PM monitors. Gas concentrations were measured with one set of analyzers by time-sharing between both barns and ambient air. The tests consisted of four trials over three pig groups or cycles: SOS in the first and second cycles, MEO in the second cycle, and MEOW in the third cycle. The treated barn with SOS resulted in 40% less NH ₃, 60-63% less TSP, 68-70% less PM ₁₀, and in one trial, 30% less odor than the control barn. MEO and MEOW slightly improved hedonic tone of barn air. The mean concentration and emissions were: 1) 18 ppm (n=132) and 55 g/d-AU (n=125, AU=animal unit=500kg)forNH ₃, 2) 98 ppb (n=153) and 0.72g/d-AU (n=129) for H ₂S, 3) 259 ppb (n=98) and 3.3 g/d-AU (n=92) for NHC, 4) 1424 μg/m ³ (n=73) and 6.07 g/d-AU (n=70) for TSP, 5) 334 μg/m ³ (n=83) and 1.6 g/d-AU (n=75) for PM ₁₀. The mean odor concentration and emission were 519 OU/m ³ (508 OUf/m ³) and 23.5 OU/s-AU (n=21). Odor, H ₂S and NH ₃ increased when flushing pits with effluent.
