摘　　要：目的监测荆门市新装修住宅室内空气中的主要污染物甲醛、菌落总数、氨、放射线的污染情况,以探讨对人体影响的因素,提出有效的预防控制措施。方法对100户新装修住宅室内空气中的甲醛、氨、菌落总数、放射线进行监测;按室内空气质量标准(GB/T 18883)判断各污染物的超标率。结果荆门市2006—2009年新装修住宅室内空气中甲醛、菌落总数的超标率分别为70.0%,12.99%,污染由重到轻依次是甲醛,菌落总数,氨,放射线。甲醛浓度与相应的采样温度作回归分析,其回归方程为Y=0.045 46+0.005 75 X。结论荆门市新装修住宅环境空气中氨、放射线污染较轻,微生物污染较重,甲醛污染状况最严重,甲醛是室内空气污染的主要物质,须采取净化处理、污染源控制、加强通风等综合措施降低室内空气中甲醛的污染。[Objective] To monitor the pollution levels of formaldehyde,total bacteria,ammonia and radiation in indoor air of newly decorated apartments in Jingmen city,study the factors that influence human health,and put forward the effective prevention and control measures. [Methods]The levels of formaldehyde,ammonia,total bacteria and radiation in indoor air were monitored in 100 newly decorated apartments,and the exceeding standard rates of pollutants were determined according to the Indoor air quality standard（GB/T 18883）. [Results]From 2006 to 2009,the exceeding standard rate of formaldehyde and total bacteria in indoor air of newly decorated apartments in Jingmen city was 70.0% and 12.99% respectively.The order of pollution degree was as follows： formaldehydetotal bacteriaammoniaradiation.The regression analysis was applied to analyze the relationship between formaldehyde concentration and related sampling temperature,and the regression equation was Y=0.045 46＋ 0.005 75 X. [Conclusion]The pollution of ammonia and the radiation in indoor air of the newly decorated apartments in Jingmen city is slight,the microbial contamination is serious,and the formaldehyde pollution is the most serious.Formaldehyde is the main substance of indoor air pollution.It is necessary to carry out the comprehensive measures which include purification,controlling pollution sources and strengthening ventilation to reduce the formaldehyde pollution in indoor air.
