摘　　要：目的调查新近装修居室空气中醛酮类物质的污染状况,为控制和消除室内空气污染提供依据。方法按装修完成时间分为三组（0-≤6个月、〉6-≤12个月,及〉12-≤18个月）进行醛酮类物质监测,以高效液相色谱法测定醛酮类污染水平（部分样品同步采用分光光度法测定甲醛及NO2含量）。结果醛酮类8种物质有不同程度检出,其中甲醛（HCHO）的检出率及超标率最高,HCHO最高检出浓度达0.69 mg/m3（我国室内空气质量标准为0.10mg/m3）,超过标准近7倍,点超标率为59.38%。而室内空气中NO2含量无超标。甲醛污染浓度在18个月内不同时间段无明显差异（P〉0.05）,但是伴随室温变化呈现正相关趋势（r=0.77,p〈0.05）。结论新近装修民居室内空气污染普遍存在,以装修初期为甚,醛酮类主要污染物质以甲醛为代表。Objective nvestigatetheputinastatusfacteneandaetadehydinindrairaierthehuseisdecratedprvidvidencesfr eliminatingandcontrollingofindoorairpollution. Methods omament group was divided into 3 groups （0_〈6 month group, 〉6〈12monthgroup, 〉12 〈18month group）. The concentration of acteone and acetaldeyde determined with HPLC method, （the concentration of some samples＇s formaldehyde and NO2 was determined by spectrophotometry）. Results 8 kinds of pollutants of acteone and acetaldehyde were detected in varing degrees,Formaldehyde had the highest detection rate and over standard rate, the highest concentration of Formaldehyde was 0.69 mg/m3,exceed the standard nearly seven times, the point exceeding standard rate of Formaldehyde was 59.38%. However,the NO2 content of indoor air without exceeding the limits. Concentrations of formaldehyde in 18 months had no significant difference between different time periods （P〉O.05）, but had a positive correlation trend with the room temperature （r= 0.77, P 〉0.05）. Conclution The indoor air pollution of newly decorated room existed widely, especially the early decoration room, formaldehyde is main indoor air pollutants of acteone and acetaldehyde.
