摘要
目的了解有烟蚊香,无烟蚊香和电蚊香片烟雾对招待所室内空气的污染状况。方法对有烟蚊香、无烟蚊香和电蚊香片在不同通风状态、不同燃烧(加热)时间下室内一氧化碳(CO)、二氧化碳(CO2)、可吸入颗粒物(IP)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;电蚊香片加热6h,以上指标均未超标。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;电蚊香片加热后各指标均未超标。结论有烟蚊香、无烟蚊香烟雾都能造成招待所室内空气污染,电蚊香片烟雾在该次实验中尚未造成招待所室内空气污染。
[Objective] To understand the indoor air pollution in hostel caused by the smoke from smoky mosquito-repellent incenses, smoke-free mosquito-repellent incenses and electric mosquito-repellent tablets.[Methods]The concentrations of CO, CO2 and inhalable particles （IP） in indoor air were measured, when these 3 kinds of mosquito-repellenat incenses were ignited（heated） under different ventilated conditions and during different length of ignited （heated） time.[Results]With the doors and windows closed, the concentrations of CO, CO2 and IP indoor exceeded after the smoky mosquito-repellent incenses being ignited; the concentration of CO indoor exceeded seriously, the concentration of CO2 indoor exceeded at some time points after the ignition of smoke-free mosquito-repellent incenses; the concentrations of CO, CO2 and IP in air indoor were all within the standards after the heating of electric mosquito-repellent tablets. With doors and windows open, only the concentration of IP exceeded after the ignition of smoky mosquito-repellent incenses, the rest were within the standards after the ignition of smoke-free mosquito-repellent incenses; concentrations of CO, CO2 and IP were within the standards after the heating of smoke-free and electric mosquito-repellent tablets.[Conclusion]The smoke of smoky and smoke-free mosquito-repellent incenses can pollute the indoor air of hostel, while the smoke of electric mosquito-repellent tablets has not resulted in indoor air pollution of hostel in this test.
