摘要
本文对上海市20户毛坯房(23个自然间)和95户精装房(133个自然间)进行了甲醛、氨、苯、TVOC和氡浓度测定,结果显示毛坯房5项指标均未出现超标,精装房室内空气污染较为严重,除氨和氡外,甲醛、苯和TVOC均出现超标,超标率分别为33.4%、2.6%和53.2%。通过对TVOC的组分浓度占比分析,乙酸丁酯、二甲苯和乙苯的浓度之和占约23%,未识别物质平均浓度占比超过8种标准物质成分总和,达到了74.49%。
To investigate the indoor air pollution levels in Shanghai, concentrations of five monomers including formaldehyde, ammonia, benzene, TVOC and radon were determined in 20 roughcast house （23 room） and 95 decorated house （133 room） .The results show that 5 indicators in the indoor air of blank housing were not exceed the limit values, but the pollutant in hardcover room was more serious, in addition to ammonia and radon, formaldehyde, benzene and TVOC were exceed the standard, exceed the standard rate were 33.4%, 2.6% and 53.2%. The proportion of butyl acetate, xylene and ethylbenzene accounted for about 23% by analyzing the proportion of TVOC components. The average content of unidentified substances accounted for more than 8 kinds of certified reference materials, which reached 74.49%.
