【摘要】 [目的]通过对装修完半年入住的居室污染物进行连续三年追踪检测,研究其污染状况和动态变化规律与人体健康效应的关系。[方法]随机抽样对选定的住户进行入户现场调查和污染物检测。[结果]室内空气污染物主要为甲醛和苯。3年的追踪监测结果表明:装修两年后空气居室中甲醛超标率仍为59.15%,处于很高水平,随时间延长甲醛浓度释放较慢。居室装修完半年的苯超标率为14.86%,随时间延长苯浓度释放较快。甲醛和苯对人体健康有一定的影响,12种症状超标组的发病人数和发病率均高于未超标组,且主要症状与其室内空气甲醛、苯浓度有一定相关性。[结论]石嘴山市室内装修空气污染严重,并且对人群健康存在一定危害。更多还原

【Abstract】 [Objective]To study the relationship of pollution status and dynamic change with human health effect,by 3-consecutive-year pollution detection.[Methods]A random sample of living rooms with half year after decoration was studied by field investigation and pollutant detection.[Results]Indoor air pollutants were mainly formaldehyde and benzene.Three-year follow-up monitoring results showed that:formaldehyde excessive rate in the air after two years house decoration was 59.15%,and the release of formaldehyde concentration decreased slowly with the time.Benzene excessive rate in the air after half year house decoration was 14.86%,the release of benzene concentration decreased fast with the time.Formaldehyde and benzene had bad influence on human health.The incidence rates of 12 symptoms and diseases were higher than those of groups in no pollution room,and the symptoms had correlation with formaldehyde and benzene concentrations.[Conclusion]In Shizuishan city,air pollution in living room is serious,and there are some hazards on human health.更多还原
