2016年7月、10月和2017年1月，对猪产生的主要有机化合物挥发性脂肪酸、酚、吲哚、醛、酮等挥发性有机化合物的浓度和化学组成进行了调查。此外，还估算了猪舍中这些组分的排放速率和年排放量。猪舍内挥发性有机物浓度夏季平均为511.3μg m−3，秋季为315.5μg m−3，冬季为218.6μg m−3。丙酮、醋酸、丙酸和丁酸是挥发性有机化合物的主要成分，占总挥发性有机化合物的80%~88%。秋冬季猪舍内VOC浓度的逐时变化表明，VOC浓度与猪舍通风量、猪群活动和猪舍温度有关。相应地，猪舍VOCs的排放量为1-2×10~3μ·g(h·kg-sine)·−·1。
The concentrations and chemical compositions of volatile organic compounds (VOCs), including volatile fatty acids, phenols, indoles, aldehydes, and ketones, which are the main organic compounds generated by swine, were investigated in July and October 2016 and January 2017. In addition, the emission rates and annual emissions of these components from the swine shed were estimated. The concentrations of VOCs in the swine shed averaged 511.3 μg m−3 in summer, 315.5 μg m−3 in fall and 218.6 μg m−3 in winter. Acetone, acetic acid, propionic acid, and butyric acid were the predominant components of the VOCs, accounting for 80–88% of the total VOCs. The hourly variations of VOC concentrations in the swine shed in fall and winter suggest that the VOC concentrations were related to the ventilation rate of the swine shed, the activity of the swine, and the temperature in the swine shed. Accordingly, the emission rates of VOCs from the swine shed were 1-2×103 μg (h kg-swine)−1.
