【摘要】 目的 :了解有烟蚊香和无烟蚊香烟雾对室内空气的污染状况。方法 :对有烟蚊香和无烟蚊香在不同通风状态、不同燃烧时间下室内一氧化碳 (CO)、二氧化碳 (CO2 )、可吸入颗粒物 (IP)及二氧化氮 (NO2 )浓度进行测定。结果 :在门窗关闭状态下 :有烟蚊香燃烧后室内CO、CO2 和IP浓度均有超标现象 ,无烟蚊香燃烧后室内CO浓度严重超标 ,室内CO2 浓度在个别时间点亦出现超标。在门窗全开状态下 :有烟蚊香燃烧后IP浓度出现超标 ,其余指标均未超标 ,无烟蚊香燃烧后各指标均未超标。两种蚊香烟雾无NO2 污染。结论 :有烟蚊香和无烟蚊香烟雾都能造成严重的室内空气污染。有烟蚊香主要造成室内IP严重污染 ,无烟蚊香主要造成室内CO严重污染。开窗通风能有效降低蚊香烟雾造成的室内空气污染物浓度更多还原

【Abstract】 Objective: To research into the influence of the smoke from the mosquito-repellent incenses in the indoor air. Methods: We observed and measured the concentrations of CO,CO 2,IP,NO 2 in the room when the smoky and no smoky mosquito-repellent incenses were ignited on the different ventilated conditions during different length of ignited time. Results: When the door and windows were shut tightly, the concentrations of CO,CO 2 and IP in the smoke of the smoky mosquito-repellent incense exceeded the standards, no matter how long it was ignited at some time point. From the no smoky one the concentrations of CO exceeded the standard seriously at all time points, and the concentrations of the CO 2 exceeded at some time points. When the door and windows were open, the concentrations of IP in the smoke of the smoky one exceeded the standard, while other concentrations were under the standards. The data of the no smoky one were all under the standards. The concentrations of NO 2 of the two types did not exceed the standards. Conclusion: The smoke from the two types of the mosquito-repellent incenses can pollute the air seriously. The smoky one mainly pollutes the air with IP, and the no smoky one mainly pollutes the air with CO. Keeping ventilative can reduce the air pollution caused by mosquito-repellent incenses effectively.更多还原
