| Outline of Final Research Achievements |
Sick-building syndrome (SBS) is a range of health problems that occur through exposure to chemicals in the indoor air. Although Ministry of Health, labour of Japan set the guideline values about 13 VOCs, the incidences of SBS patients have not decreased. In addition, there have been reports that when people complain of symptoms of SBS, most of them also claim to smell an odour. Furthermore, the occurrence of SBS symptoms depends largely on the person's sensitivity.
In this study, the correlation between the sum of VOCs (ΣVOCs) and SBS symptoms were examined by statistics. The odour was quantified using the odour threshold ratio (OTR) and the correlation between the total odour threshold ratio (TOTR) and SBS symptoms was investigated. TOTR and the concentration level of ΣVOCs were correlated with SBS symptoms among sensitive people. The findings indicate that TOTR, in addition to ΣVOCs, could be used as a new risk indicator for human health regarding indoor air quality.
