SURVEY ON AIR POLLUTION AFTER INDOOR DECORATION AND ITS DAMAGE

[Objective]To explore the situation of air pollution after indoor decoration and the countermeasures.[Methods]Air samples on the months of 1、3、6 after indoor decoration were collected from 23 households to detect the densities of formaldehyde and benzene.Meanwhile,an epidemiological survey on adverse reactions of eyes and respiratory system of family members were conducted.[Result]The concentration of formaldehyde in door air was 1.9 more times higher than the standard,and the concentration of benzene was 4.25-12.4 more times than the standard.The degree of air pollution declined with the time.After indoor decoration,the incidence of tearing,sneezing,bronchitis,cough,asthma and dizziness of family members increased from 0%,3.5%,3.5%,0% to 7.1%,8.2%,7.1%,8.2%,respectively.[Conclusions]Indoor decoration can lead to pollution of formaldehyde and benzene in the air,which is in proportion to complicacy of decoration,and is relevant to the quality of decoration materials.Decoration also results in the increase of adverse reactions of eyes and respiratory system.
