室内空气中氮氧化物卫生标准的制订方法和依据

The Study on the Method and Basis of Hygienic Standard for Nitrogen Oxides in Indoor Air

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。

To study the method and basis of hygienic standard for nitrogen oxides in indoor air On the basis of reading up the chinese and foreign documents about the study on nitrogen oxides(NO x ),the criteria of average daily concentrations of NO x in indoor air should not go beyond the limit of 0 20 mg/m 3 according to the threshold limit value of the effect of NO x on the human health It is considered that living conditions and environment of the citizens have being improved And a comparison was made between the pollution level of NO x in indoor air in China and the results of the verified test,it was renommentd that the maximum allowable average daily concentration of NO x in indoor air was 0 10 mg/m 3
