Abstract
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.
