Dampness deteriorates indoor air quality. This study aims at finding out the relationship between dampness score and levels of common indoor air quality indicators including CO2, PM2.5, temperature, relative humidity and concentrations of indoor fungi. A survey was used to develop a dampness score and the indoor air quality was measured using a real-time indoor air quality sensing monitor (ESCORT, South Korea) and a collector for fungi measurement (KAS-110, Kemik Corporation, Seongnam, SouthKorea) among asthmatics’ home. A statistical package was used to evaluate the relationship between dampness score and indoor air quality variables. The spearman correlation coefficient between the dampness score and carbon dioxide was .642 indicating a strong correlation (p<.05). A significant correlation between the dampness score and the concentration of mold in the bedroom was also found ( .315, p<.05).
The correlation coefficient between the dampness score and the relative humidity was .40 (p<.05). The correlation coefficients between the dampness score and PM2.5 or temperature were .02 or .014, respectively. This study found that dampness score was mainly determined by indoor CO2, fungi concentration and relative humidity. |
