室内挥发性有害有机物限量标准研究

Study on the limit standard for indoor hazardous volatile organic gas

室内挥发性有害有机物的种类繁多,我国现有室内空气质量标准中有机物的限量指标只有甲醛、苯、甲苯、二甲苯、TVOC 5种。我们通过研究发现室内空气中17种有机挥发性有害物质出现的频率较高,浓度较大,且对人体健康有很大的危害,世界各国和各地区的空气质量标准分别对这17种物质中的部分组分给出了安全限量。通过科学分析我们建议了涵盖甲醛、烷烃类、卤代烃类、苯系物等的室内挥发性有害有机物限量标准,使我国的室内空气质量控制指标更具有效性和针对性。

There are many kinds of indoor hazardous volatile organic gases. However,only five of them are quantitatively regulated in present national standard of China for indoor air quality, i. e formaldehyde, benzene, toluene, xylene, TVOC （total volatile organic compounds） .According to the study, seventeen organic gases are frequently found indoor, which are also found in high concentration. Besides, those seventeen gases are deleterious to human.The air quality standards world-wide have covered part of them respectively.Through scientific analysis the authors suggest a limit standard for indoor hazardous volatile organic gases including formaldehyde, alkane, halogenated hydrocarbon and benzene series. The proposed standard will bring more validity and pertinency to indoor air quality control.
