摘要
目的了解不同类型蚊香烟雾对室内空气污染的状况。方法在关窗条件下,对3种蚊香使用后不同时间室内一氧化碳(CO)、二氧化碳(CO2)、可吸入颗粒物(IP)和总挥发性有机物(TVOC)的浓度进行测定。结果有烟蚊香使用后不同时间室内CO、IP浓度均超过室内空气质量标准,TVOC浓度在使用5和6 h后超标,CO2浓度未超标;无烟蚊香使用后不同时间室内CO和TVOC浓度均超标,CO2和IP浓度均未超标;电蚊香片使用后不同时间室内CO、IP、CO2和TVOC浓度均未超标。有烟蚊香产生的CO、CO2、IP和TVOC均与时间呈正相关关系(P<0.01);无烟蚊香产生的CO、CO2和TVOC与时间呈正相关关系(P<0.01),但IP与时间无相关性(P>0.05);电蚊香片产生的TVOC与时间呈负相关关系(P<0.01),但CO、CO2和IP与时间无相关性(P>0.05)。蚊香使用3及6 h后,CO、CO2污染情况:有烟蚊香显著高于无烟蚊香,无烟蚊香显著高于电蚊香片;TVOC污染情况:无烟蚊香显著高于有烟蚊香,有烟蚊香显著高于电蚊香片;IP污染情况:有烟蚊香显著高于无烟蚊香和电蚊香片,而无烟蚊香和电蚊香片间差异无统计学意义。结论有烟蚊香主要造成室内IP、CO和TOVC污染,无烟蚊香主要造成室内CO和TVOC污染,电蚊香片主要产生TVOC污染。
[ Objective ] To investigate the indoor air pollution from the smoke of different kinds of mosquito coils. [ Methods ] Under the condition of closing doors and windows, the concentrations of CO, CO2 , IP and TVOC at different time were measured after the mosquito coils being used. [ Results] The concentrations of CO and IP from smoky mosquito coils exceeded the indoor air quality standards, and the concentration of TVOC exceeded the standard after 5 hours and 6 hours, but the concentrations of CO2 did not exceed the standards; the concentrations of CO and TVOC of smokeless mosquito coils exceeded the standards, but the concentra- tions of CO2 and IP did not exceed the standards ; the concentrations of CO, CO2 , IP and TVOC from electric mosquito coils did not exceed the standards. The concentrations of CO, CO2 ,IP and TVOC of smoky mosquito coils had a significantly positive correlation with the time( P 〈0.01 ) ; the concentrations of CO, CO2 and TVOC of smokeless mosquito coils had a significantly positive correla- tion with the time ( P 〈 0.01 ) , the concentration of IP had no correlation with the time ( P 〉 0.05 ). The concentrations of TVOC of electric mosquito coils had a negative correlation with the time ( P 〈 0. 01 ) , the concentrations of CO, CO2 and IP had no correlation with the time ( P 〉 0.05 ). After 3 hours and 6 hours, in terms of CO and CO2 , the smoky mosquito coils was higher than the smokeless mosquito coils, the smokeless mosquito coils was significantly higher than the electric mosquito coils ; in terms of TVOC, the smokeless mosquito coils was significantly higher than the smoky mosquito coils, the smoky mosquito coils was significantly higher than the electric mosquito coils ; in terms of IP, the smoky mosquito coils was significantly higher than the smokeless mosqui- to coils and the electric mosquito coils, the smokeless mosquito coils had no statistical difference with the electric mosquito coils. [ Conclusion] Smoky mosquito coils primarily causes indoor CO, IP and TVOC pollution. Smokeless mosquito coils can always cause serious CO and TVOC pollution. Electric mosquito coils primarily causes TVOC pollution.
