| 摘 要： | 用GC-PID和GC-FID两种方法分析了室内空气中的苯，实验表明，两种方法的分析结果具有很好的相关性；运用GC-PID方法，分析北京市一些室内空气中的苯，结果表明，装修对室内空气中苯的浓度影响较大，特别是装修不到一年的办公室，其空气中苯的浓度超标率最高，达到30．3％．

| Abstract: | Comparison between two analysis techniques,GC PID and GC FID,for analyzing ambient benzene was carried out.There was a significant correlation( R 2>0 9897)among the values obtained with both techniques.It indicated that GC PID is more convenient for benzene analysis because it can be used to analyze ambient benzene directly without preconcentration.From March to August in 2002,we measured benzene in some indoor environments in Beijing by GC PID.The results showed that decoration led to obvious increase of benzene levels in indoor air,especially in the offices furnished for less than one year.In these offices,the over standard rate of benzene was 30 3% and the average concentration of benzene exceeded hygienic standards. |
