Meat-grilling restaurants are considered to be residential emission sources of air pollutants. To investigate the emission characteristics of particulate matter (PM), odors, and volatile organic compounds (VOCs) from the grilling of meat, a grilling apparatus equipped with butane gas burners was used to grill pork belly and marinated pork ribs in a laboratory setting. When grilling the pork belly, the emission factor for PM with a diameter of 2.5 μm or below (PM2.5) was 754 mg-PM·kg-meat-1, accounting for 99% of total suspended particles (TSPs), while that of the marinated pork ribs was 137 mg-PM·kg-meat-1 (96% of TSPs). Ammonia and acetaldehyde were the most common odors emitted during grilling at 43-88 mg·kg-meat-1 and 22-30 mg·kg-meat-1, respectively. Aldehydes were the most significant contributor to total odor intensity (36%-67%). Benzene, vinyl acetate, and hexene were the most abundant VOCs for the pork belly, while butane, vinyl acetate, and n-dodecane were the most abundant for the marinated ribs. Among the VOCs emitted from the pork grilling process, hexene, butane, and toluene were the dominant ozone precursors. The information obtained in this study is useful for furthering the understanding of the characteristics of air pollutants emitted from actual meat-grilling restaurants. Additionally, knowledge of the PM, odor, and VOC emission characteristics and their emission factors is useful for establishing management strategies for air pollutants from meat-grilling restaurants.

猪肉烧烤过程中产生的颗粒物,气味和挥发性有机化合物的排放特征。

肉食餐厅被认为是空气污染物的住宅排放源。为了研究烤肉过程中颗粒物质(PM),气味和挥发性有机化合物(VOC)的排放特性,在实验室环境中,使用配备了丁烷气燃烧器的烧烤设备来烤五花肉和腌制的排骨。烧烤猪肚时,直径为2.5μm或以下的PM(PM2.5)的排放因子为754 mg-PM·kg-meat-1,占总悬浮颗粒(TSPs)的99%,而腌制排骨的含量为137 mg-PM·kg-meat-1(占TSP的96%)。烧烤过程中,氨和乙醛是最常见的气味,分别以43-88 mg·kg-肉1和22-30 mg·kg-肉1排放。醛是总气味强度的最大贡献者(36%-67%)。苯,乙酸乙烯酯和己烯是五花肉中最丰富的VOC,而丁烷,乙酸乙烯酯和正十二烷是腌制排骨中最丰富的VOC。在猪肉烧烤过程中排放的挥发性有机化合物中,己烯,丁烷和甲苯是主要的臭氧前体。这项研究中获得的信息有助于进一步了解实际肉食餐厅排放的空气污染物的特征。此外,了解PM,气味和VOC排放特性及其排放因子对于建立肉类烧烤餐厅的空气污染物管理策略很有用。在猪肉烧烤过程中排放的挥发性有机化合物中,己烯,丁烷和甲苯是主要的臭氧前体。这项研究中获得的信息有助于进一步了解实际肉食餐厅排放的空气污染物的特征。此外,了解PM,气味和VOC排放特性及其排放因子对于建立肉类烧烤餐厅的空气污染物管理策略很有用。在猪肉烧烤过程中排放的挥发性有机化合物中,己烯,丁烷和甲苯是主要的臭氧前体。这项研究中获得的信息有助于进一步了解实际肉食餐厅排放的空气污染物的特征。此外,了解PM,气味和VOC排放特性及其排放因子对于建立肉类烧烤餐厅的空气污染物管理策略很有用。
