贵阳市民居室内外空气污染物分布及来源研究

Study on the Distribution and Sources of Indoor and Outdoor Air Pollutants in Domiciles in Guiyang City

对贵阳市部分家庭室内外空气污染物进行了监测，并对其来源进行了分析。结果表明，除了CO浓度未超标外，SO2、NO2、PM10、CO2、甲醛和氨均出现不同程度的超标，超标率在0.5％～38％，最大超标倍数1．1～2，7，其中PM10的超标率扣甲醛的超标倍数最明显。室内空气污染物中，PM10、CO、CO2和甲醛主要来自室内源的贡献，SO2则受室外源的影响大。污染物在室内不同房间之间具有较高的相关关系。

The indoor and outdoor environmental pollutants in some domiciles in Guiyang city were measured and sources of these pollutants were analyzed. The result showed that except carbon monoxide, the consistence of sulfur dioxide, nitrogen dioxide, PM10 （Particles with aerodynamic diameters smaller than 10μm）, carbon dioxide, formaldehyde, ammonia were above standard in some degree. The percentage index was 0.5 % - 38% above standard. Furthermore,the maximal multiple was 1.1 - 2.7 above standard. The limit- exceeding percentage of PM10 mass concentration and exceeding multiple of formaldehyde consistence in domiciles were the most obvious, Among these pollutants in indoor air, PM10, carbon monoxide, and carbon dioxide were mainly from indoor sources, while sulfur dioxide was mainly from outside sources. Pollutants had high - level correlations between living room and kitchen.
