摘　　要：对上海市某综合型城市地下空间空气进行采样、监测,得到CO 2、TVOC、甲醛、微生物、PM 10、PM 2.5等6类污染物的特征分布,基于国内外不同的空气质量标准作分析比较。结果表明,该典型综合型地下空间的空气污染情况较普遍,其中甲醛、TVOC污染较为突出,平均浓度超标倍数分别为1.056倍、3.755倍;共发现9种潜在致病菌属,占总数的0.893%。地下空间污染物的累积与内部建筑的设计、装修、功能属性、空调系统等众多因素有关。The distribution of six types of pollutants including CO 2、TVOC、HCHO、microbes、PM 10、PM 2.5 were studied by collecting and monitoring the air in a comprehensive underground space in Shanghai.Compared with domes tic and foreign air quality standards,the air quality in this comprehensive underground space was generally polluted,HCHO and TVOC pollution were severe,the exceeding rate of the average concentration were 1.056,3.755,respectively.Nine potential pathogenic bacteria genera were identified,accounting for 0.893%of the total.The accumulation of pollutants in the underground space was affected by architectural design,decoration,functional properties and air conditioning system inside the building.
