为探讨室内空气氮氧化物卫生标准的制定方法及依据，在大量查阅国内外有关氮氧化物研究资料的基础上，根据氮氧化物产生各种危害作用的阈浓度，提出我国室内空气中氮氧化物日平均浓度不宜超过０．２ｍｇ／ｍ３，结合我国氮氧化物污染水平和对建议值的验证实验，同时考虑到我国人民生活水平的提高和住宅室内条件的改善，最后确定我国室内空气中氮氧化物日平均最高容许浓度建议值为０．１０ｍｇ／ｍ３。
In order to explore the method and basis for the development of hygienic standards for indoor air nitrogen oxides, based on a large number of domestic and foreign research data on nitrogen oxides, based on the threshold concentrations of various harmful effects of nitrogen oxides, the nitrogen oxides The daily average concentration should not exceed 0.2mg / m3. Combined with the nitrogen oxide pollution level in our country and the verification test of the recommended value, taking into account the improvement of people’s living standard and the improvement of indoor conditions in our country, we finally determine the nitrogen The daily average maximum allowable oxide concentration suggested 0.10mg / m3.
