室内空气污染物的种类及控制措施

室内空气污染物包括悬浮固体污染物和气体污染物。其中可吸入颗粒物对人体呼吸系统有极大危害，引起肺炎、肺癌等疾病，主要来源于燃料的燃烧、吸烟以及由室外进入室内的颗粒物。气体污染物主要包括有机气体污染物(挥发性有机物、甲烷等)和无机气体污染物(SO2、NOx、CO等)，它们可引起病态建筑综合症、化学物质过敏症(MCS)等相关病症。本文分析了室内空气污染的影响因素，并据此提出了控制室内空气污染以及提高室内空气质量的方法与措施。

Types and Controlling Measurements of Indoor Air Pollutants

Indoor air pollutants consist of suspended solid pollutants and gaseous pollutants. Suspended solid pollutants, mainly inhalable particles, have much adverse influence on respiratory system,causing pneumonia and lung cancer. They mainly come from fuel combustion, smoking and outdoor sources. Gaseous pollutants are aminly composed of organic gases (volatile organic compounds, formaldehyde etc.) and inorganic gases ( sulfur dioxide, nitrogen oxides, carbon monoxide etc). Some diseases,such as sick building syndrome ( SBS ) and multiple chemical sensitivity ( MCS ) are closely related to gas pollutants. The paper analyzes factors influencing indoor air quality and the countermeasures for preventing indoor air pollution and improving indoor air quality are further suggested.
