Abstract The odor pollution and health risk caused by intensive livestock buildings are a public concern. In this study, the concentration, odor pollution, and health risk from volatile organic compounds (VOCs) released from different locations on a swine farm (swine nursery house, fattening swine house, manure storage, plant boundary and upwind locations) in different seasons (spring, summer, and fall) were evaluated quantitatively. The average VOC concentrations were 125.5, 1504.7, and 1698.5 μg/m3 in spring, summer, and winter, respectively. The total odor activity value (OAVSUM) of manure storage was the highest, with methanethiol, dimethyl sulfide (DMS), and H2S as the major contributors. Cumulative noncarcinogenic emissions exceeded the threshold in summer at all locations, except at the plant boundary and upwind locations. Furthermore, the cumulative carcinogenic risk threshold was also exceeded at the fattening swine house and manure storage area during the summer. Therefore, to protect farm staff working near the animal housing facilities, special attention should be paid to minimize the odorous nuisance and noncarcinogenic and carcinogenic risks.

猪场挥发性有机化合物排放的恶臭污染特征及健康风险评估

摘要 集约化畜舍所造成的气味污染和健康风险已成为公众关注的问题。在本研究中，猪场不同位置（猪舍、育肥猪舍、粪便储存库、植物边界和上风位置）释放的挥发性有机化合物（VOCs）在不同季节的浓度、气味污染和健康风险（春季、夏季和秋季）进行定量评估。春季、夏季和冬季的平均 VOC 浓度分别为 125.5、1504.7 和 1698.5 μg/m3。粪便储存的总气味活性值 (OAVSUM) 最高，其中甲硫醇、二甲硫醚 (DMS) 和 H2S 是主要贡献者。除工厂边界和逆风位置外，所有地点的累积非致癌排放在夏季均超过阈值。此外，育肥猪舍和粪便储存区在夏季也超过了累积致癌风险阈值。因此，为了保护在畜舍设施附近工作的农场工作人员，应特别注意将异味滋扰和非致癌和致癌风险降至最低。
