Koreans have sedentary lifestyles and use under-floor heating called Ondol as home heating systems. Sick Building Syndrome (SBS) caused by VOCs released from flooring material has been of significant interest in residential apartments. In this study, we measured exposure to VOCs by having test subjects breathe under conditions of high surface temperature. The results showed that the emission level of VOCs was high at 40oC in the early stage of the experiment. However, 20 days after the experiment began, the emission level was reduced by 0.9-4 times in each product at 40oC. The exposure to VOCs released from floor coverings was measured by taking into account the average respiratory rate, weight, and activity hour of test subjects and presuming that people are exposed to VOCs all the time while staying indoors. The level of emission from FJR of low-cost PVC floor coverings was the highest among the tested coverings, but the exposure to VOCs emission from the covering was relatively low at 0.025 mg/kg/day at 40oC. The amount of toluene detected from this experiment was the highest among VOCs emitted from floor coverings. The hazard quotient (HQ) of toluene detected in this test was over 20 times smaller than the risk characterization level of 0.1. It was, therefore, estimated that the emission of toluene from the floor surface would not be critically harmful to residents.
