摘要
目的了解居室装修完工后空气中苯随时间的变化趋势。方法按装修程度分为低装修程度组、高装修程度组、家具装填组,按居室面积分为80、110、142 m2,居室空气中苯的测定按照《民用建筑工程室内环境污染控制规范》(GB 50325–2006)溶剂解吸气相色谱法进行。结果不同居室面积苯质量浓度均值范围为0.16 mg/m3~0.34 mg/m3,低装修程度组第1次—第5次室内苯浓度均在国家限值以下,高装修程度组和家具装填组降低到安全水平时分别为98 d和118 d。结论随时间延长室内苯浓度呈降低趋势,118 d后苯浓度均能降低到安全水平。
Objectives To investigate the variation of benzene concentration in indoor air after being decorated. Methods The degree of contamination were detected in the air of rooms with low and high decorated levels according to the extent of decoration,the fullness of rooms with furniture,and room areas of 80,110 and 142 square meters. The concentration of benzene in indoor air was measured according to the Code for Indoor Environmental Pollution Control of Civil Building Engineering(GB 50325- 2006),and the desorbed solvents were detected by gas chromatography. Results The average benzene concentration in different room areas was in the range of 0. 16 ~ 0. 34 mg/m3. The concentration of benzene in indoor air of low decorated rooms was below the national limit in the 1stto 5thdetection,while the concentration of benzene in indoor air of high decorated rooms and rooms filled with furniture was lower than the national limit until 98 days and 118 days later,respectively. Conclusions Benzene concentration in indoor air was decreased with the extension of time,and reached to a safe level in118 days.
