Emissions of volatile organic compounds from interior ...

Mar 01, 2020· Fig. 2 shows the variation of TVOC concentration and VOC composition as the result of exposure of the LCS sample to the two air temperatures. At 25 °C, TVOC concentration increased at the beginning of the emission to 200 μg/m 3 by the second hour. After the fifth hour, the concentration gradually decreased to around 170 μg/m 3 and remained relatively stable by the end of the experiment.
