摘要
目的了解石家庄市不同时间装修的居室空气质量情况。方法于2003年6月,选择石家庄市装修2a之内的220户家庭,按装修时间分为3个月以内,3个月～1a,1a～2a3个组。检测室内空气中的甲醛、氨、苯、甲苯、二甲苯浓度,并进行比较。结果室内空气中甲醛、氨气、苯、甲苯和二甲苯的超标率分别为51.63%,42.13%,5.39%,7.46%和7.69%。装修后3个月以内、3个月～1a、1a～2a组居室的空气质量合格率分别为33.87%,52.46%和60.00%。3组之间差异有统计学意义(P<0.01),其中,3个月以内组中,添置新家具的住户室内空气合格率低于未添置新家具的住户。结论石家庄装修居室空气污染较严重,随着装修后的时间延长,居室空气污染有所好转。
