摘　　要：在石家庄市内选取部分新装修装饰的民用住宅进行室内空气采样,对甲醛、苯、甲苯、二甲苯和TVOC分别采用酚试剂分光光度法和气相色谱法进行分析。测定结果表明:新装修装饰后的室内空气中甲醛、苯、甲苯、二甲苯和TVOC存在不同程度的超标现象,其中,甲苯污染相当严重,最大超标倍数为17.7;卧室中甲醛、苯、甲苯、二甲苯和TVOC等污染物的超标率普遍高于客厅,其中卧室甲醛超标率约为客厅的2倍;室内空气中甲醛浓度随着密闭时间的增加持续增加。最后提出一系列相应的防治措施与建议。The indoor air in some new decorated houses in Shijiazhuang was selected to sample,formaldehyde,benzene,methylbenzene,dimethylbenzene and TVOC were analyzed by spectrophotometry and gas chromatography. The results showed that formaldehyde,benzene,methylbenzene,dimethylbenzene and TVOC in the indoor air of new decorated houses exceeded the standard in some degree. The methylbenzene pollution was more serious,and its largest multiples of exceeding standard was 17.7. The concentrations of formaldehyde,benzene,methylbenzene,dimethylbenzene and TVOC in bedrooms were generally higher than that of living rooms,the ratio of exceeding standard of formaldehyde was significantly higher than living room,which was about two times than the latter. The concentrations of formaldehyde in indoor air continuously increased with the confined time. Finally a series of corresponding measures and proposals were proposed.
