一氧化碳(CO)是餐厅空气监测的一项重要卫生指标,它的主要来源是食物加工过程中燃料的燃烧和就餐人群吸烟,尤以直接在餐厅中加工食物者为甚。因此,我们选择在餐厅中直接加工食物的餐厅,包括采用木炭作燃料的火锅餐厅、采用液化气作燃料的火锅和烧烤餐厅、采用固体酒精作燃料的 Carbon monoxide (CO) is an important hygienic indicator of restaurant air monitoring. The main source of CO is fuel burning in food processing and smoking in dining crowds, especially where food is processed directly in the restaurant. Therefore, we have chosen restaurants that directly process food in the restaurants, including hot pot restaurants that use charcoal for fuel, hot pots and grill restaurants that use liquefied gas for fuel, and solid alcohol for fuel
