【摘要】：目的了解南宁市新装修居室空气污染状况及其对人体健康的影响。方法按照GB/T18883—2002《室内空气质量标准》对南宁市2002—2006年130户新装修居室内空气中甲醛、苯、甲苯、二甲苯和放射性水平进行检测;对25户室内空气中甲醛浓度超标的居室进行跟踪检测,并对居民健康状况进行问卷调查。结果130户新装修居室空气样本甲醛浓度合格率为25.6%,氨浓度合格率为27.1%,平均浓度超标倍数分别为3.88倍和1.35倍;而放射性水平及苯、甲苯、二甲苯浓度合格率分别为99.6%,97.6%,89.5%,91.9%。25户室内空气甲醛浓度超标居室入住6～12个月后空气甲醛浓度低于人住时(P0.01)。健康状况问卷调查结果显示,居民入住时均有不同程度的不良反应出现,其中以咽喉疼痛的发生率最高,达92%。结论甲醛和氨是南宁市新装修居室环境中最主要的污染物,新装修居室空气污染已对人体健康产生一定程度的影响。
[Abstract]:Objective to investigate the air pollution in newly decorated rooms in Nanning and its effect on human health. Methods according to GB / T 18883-2002 indoor air quality standard, the levels of formaldehyde, benzene, toluene, xylene and radioactivity in 130 newly decorated indoor air of Nanning from 2002 to 2006 were detected. The indoor air formaldehyde concentration in 25 rooms was followed up and the health status of the residents was investigated. Results the qualified rate of formaldehyde concentration and ammonia concentration in air samples of 130 newly decorated rooms were 25.6 and 27.1 respectively. The qualified rate of the concentration of xylene was 99.6 and 97.6, respectively. The formaldehyde concentration in the air of 25 households was lower than that in the living room (P0.01) after the indoor air formaldehyde concentration exceeded the standard for 6 ~ 12 months (P0.01). The results of health survey showed that there were different degrees of adverse reactions in residents, and the incidence of throat pain was the highest, reaching 92%. Conclusion formaldehyde and ammonia are the most important pollutants in the newly decorated living environment in Nanning. Air pollution in newly decorated rooms has a certain degree of impact on human health.
