摘　　要：目的:分析2020~2022年50套兰州市新装修房屋室内主要空气污染物甲醛、总挥发性有机物、氨、苯、甲苯和二甲苯监测数据,为有效控制室内空气污染提供科学依据。方法:选取兰州市新装修6个月内的50套房屋作为检测对象,检测室内甲醛、总挥发性有机物(TVOC)、氨、苯、甲苯和二甲苯浓度。结果:50套新装修房屋内,甲醛超标率为16.0%,总挥发性有机物超标率为86.0%,氨超标率为8.0%,苯超标率为6.0%,甲苯和二甲苯超标率为0.0%。结论:兰州市50套新装修房屋室内空气中甲醛和总挥发性有机物(TVOC)严重超标,氨和苯也不同程度超标,提示总挥发性有机物(TVOC)污染已成为室内空气污染物的主要来源,应引起重视。Objective:To analyze monitoring data of major air pollutants in Newly Decorated Rooms of Lanzhou from 2020 to 2022,so as to provide scientific basis for effectively controlling indoor air pollution.Methods:50 houses that were newly redecorated for six months were chosen for the determination of formaldehyde,total votatile organic compounds(TVOC),ammonia,benzene,toluene and xylene.Results:In 50 newly decorated houses,the over-standard rate of formaldehyde,TVOC,ammonia and benzene were 16.0%,86.0%,8.0% and 6.0%.The over-standard rate of toluene and xylene were 0.0%.Conclusion:The concentration of formaldehyde and TVOC went beyond the standard greatly in 50 newly decorated houses.The concentration of ammonia and benzene exceeded standards variously.TVOC become the main sources of indoor air pollution.
