摘要
目的比较甲醛和苯在室内装修后的浓度下降特征。方法选择装修后1周内、1年内和1年以上的旅馆 ,进行甲醛和苯浓度的测定。结果苯的浓度在装修后1周内最高 ,均值为0.534mg/m3,以后逐渐降低。而甲醛在装修后1周内的浓度并不高 ,以后逐渐升高 ,装修后1年内的甲醛浓度最高 ,均值为0.141mg/m3,然后再逐渐下降。结论室内装修后 ,甲醛和苯的浓度下降趋势不同。
Objective To compared the decreasing characteristics of formaldehyde and benzene concentrations in indoor air after decoration. Methods The concentrations of formaldehyde and benzene in indoor air of hotels were determined within one week, one year and more than one year after decoration. Results The concentrations of benzene in indoor air reached the peak(mean: 0.534 mg/m 3) within one week after decoration, and then decreased gradually.The concentrations of formaldehyde were not high within one week after decoration,and then increased gradually, reached the peak (mean: 0.141 mg/m 3) within one year after decoration,then decreased gradually. Conclusion After decoration,the decreasing characteristics of the concentrations of formaldehyde and benzene showed a difference that the concentrations of benzene decreased faster than that of formaldehyde did.
