Abstract
This review is described about the flow of TVOC as the indoor air quality indicator, the definition, the measuring method, the biological influence, the standard value, the defect and effect, the significance of existence, and how to use it.
TVOC was proposed assuming that the possibility of the pollution influence was shown as the overall, simple notation of VOC that many kinds exist in the indoor air. And, it has been used in a lot of surveillances and studies. However, TVOC cannot become an essential, toxic academic indicator. Moreover, the defect as the that shows the pollution level is pointed out in a present VOC•TVOC measuring method so that the missed small amount stimulatory component may exist. On the other hand, because a lot of VOC to which the standard value is not set coexists, TVOC has the meaning as an rough environmental management indicator to achieve the decrease of the VOC risk through both monitoring of VOC from the source in buildings and evaluation of VOC from construction materials.
