火锅店室内空气污染调查

Indoor Air Pollution in Chaffy Dish Restaurant

目的了解使用不同燃料或灶具的火锅店室内空气污染状况。方法于2006年3月选择燃料为液化气或木炭的火锅店,于营业前和营业后30、60、90、120、150min测定室内空气中的CO、CO2、可吸入颗粒物(IP)浓度。结果使用不同燃料或灶具的火锅店营业前除IP超标外,CO、CO2均未超标。营业后,使用液化气红外线灶的火锅店CO浓度未超标,其余各就餐场所CO、CO2、IP浓度均超标,木炭火锅店CO浓度超标最严重,营业后5个监测时间点的超标率均为100%,最高超标6.4倍。液化气红外线灶火锅店CO、CO2、IP浓度均显著低于液化气普通灶火锅店,木炭火锅店CO浓度显著高于液化气灶火锅店。结论火锅店室内空气污染严重,对用餐人群的健康构成潜在危害。

Objective To investigate the indoor air pollution of chaffy dish restaurant using different kinds of fuels or utensils. Methods The concentration of carbon monoxide （CO）, carbon dioxide （CO2） and inhalable particle （IP） were determined 30, 60, 90, 120 and 150 minutes respectively before and after the chaffy dish restaurants were opened in Mar. 2006. Results Before the restaurants were opened, the concentrations of CO and CO2 except IP did not exceed the standard limits. After opened, the concentrations of CO, CO2 and IP in chaffy dish restaurants which use different kinds of fuels or utensils exceed the standard limits in different degrees except the concentration of CO in chaffy dish restaurant using the infrared utensil. The concentration of CO in chaffy dish restaurant that used charcoal as fuel was the highest and more than the standard limits by 7 times. The concentrations of CO, CO2 and IP in chaffy dish restaurants which used the infrared utensil were obviously lower than those in which used the common liquefied gas utensil. The concentration of CO in chaffy dish restaurants which used charcoal as fuel was obviously higher than those used liquefied gas utensils. Conclusion The indoor air pollution of chaffy dish restaurants is extremely severe and it has the potential harm to the health of the customers in restaurants.
