The methods for sampling and analyzing 10 carbonyl compounds such as formaldehyde, acetaldehyde, acrolein, acetone, propionaldehyde, crotonaldehyde, butyraldehyde, benzaldehyde, cyclohexanone, valeraldehyde in indoor air were proposed with the sampling efficiency, recovery and detection limit being 92% - 100%, 91% - 104%, 0.26ng/m3 - 0.82ng/m3, respectively. Pollution survey of 10 carbonyl compounds in air of 6 trains was conducted. It was indicated that the total concentrations of carbonyl compounds were 0. 1591 mg/m3 - 0.2828 mg/m3 with the average concentration of 0.2330 mg/m3, the average concentrations of formaldehyde, acetaldehyde and acetone were 0.0922 mg/m3, 0.0499 mg/m3 and 0.0580 mg/m3, accounted for 42.6%, 21.4%, 24.9% of the total carbonyl compounds' concentrations, respectively. The carbonyl compounds probably came from woodwork and tobacco. The intake of carbonyl compounds for the passengers was approximately 0.043 mg/h - 0.076 mg/h.
提出了室内空气中甲醛、乙醛、丙烯醛、丙酮、丙醛、巴豆醛、丁醛、苯甲醛、环己酮、戊醛等10种羰基化合物的采样与分析方法，采样效率为92% - 100%，回收率为91% - 104%，检测限为0.26ng/m³ - 0.82ng/m³。对6列火车车厢内空气进行了10种羰基化合物的污染调查。结果表明，羰基化合物总浓度为0.1591mg/m³ - 0.2828mg/m³，平均浓度为0.2330mg/m³，甲醛、乙醛和丙酮的平均浓度分别为0.0922mg/m³、0.0499mg/m³和0.0580mg/m³，分别占羰基化合物总浓度的42.6%、21.4%、24.9%。羰基化合物可能来自木制品和烟草。乘客羰基化合物摄入量约为0.043mg/h - 0.076mg/h。
