室内空气中氮氧化物污染水平及其影响因素的探讨

为制定我国室内空气中氮氧化物（ＮＯｘ）卫生标准，采用现场监测和实验室模拟相结合的方法，对室内空气中ＮＯｘ的污染水平及其影响因素进行研究。结果表明，冬季燃烧原煤的厨房、卧室空气中ＮＯｘ日平均浓度分别为０．１５９ｍｇ／ｍ３、０．１３２ｍｇ／ｍ３，燃烧煤气的厨房、卧室空气中ＮＯｘ日平均浓度分别为０．０９１ｍｇ／ｍ３、０．０７８ｍｇ／ｍ３，燃烧液化气分别为０．０７０ｍｇ／ｍ３、０．０６４ｍｇ／ｍ３。冬季与夏季室内空气中ＮＯｘ日平均浓度有显著性差异，冬季比夏季严重，厨房比卧室严重，未使用排油烟机的比使用排油烟机的严重

Study on the Pollution Level of Nitrogen Oxides in Indoor Air and Its Influential Factors

In order to offer the reference to working out the hygienic standard for Nitrogen Oxides(NOx)in indoor air,in this research,the NOx pollution level and its influential factors were studied with the methods of combining the environmental monitoring with the simulated test.The results showed that the average daily cocentrations of NOx are about 0 159mg/m 3 in the kitchen and 0 132mg/m 3 in the bedroom respectively with coal stoves;0 091mg/m 3 in the kitchen and 0 078mg/m 3 in the bedroom with coal gas;0 070mg/m 3 in the kitchen and 0 064 mg/m 3 in the bedroom with liquefied gas in winter.It is shown that the NOx pollution in indoor air with coal stoves is significantly heavier than those with coal gas stoves and liquefied gas stoves,in winter than in summer,in the kitchens than in the bedrooms,in thec ase of using removing oil smoke equipment than the case of not using them.
