Testing of volatile organic compounds in a newly decorated office building

In order to explore the release characteristics of the volatile organic compounds in decorated buildings, using the method of active carbon absorption combined with gas chromatographic analysis, monitors the indoor pollutant concentration in four rooms in an office building in Tianjin. Obtains the variation regularity of indoor air pollutants, that is, their concentrations decrease after decoration. However, the concentrations may go up transitorily with the variation of indoor air temperature, relative humidity and air distribution.
