| Outline of Final Research Achievements |
We conducted questionnaire survey and field measurements on 6 cities in China. Results of the questionnaire survey suggested the association between mold and chemical pollution and children’s allergic diseases. The results also showed that the prevalence of allergic diseases in southern three cities was higher than that in northern three cities. On the other hand, results of the field measurements showed that there was no difference in air concentrations of fungus and chemical substances between the groups with and without allergic diseases. However, concentrations of TVOC and PM2.5 were higher in southern cities than in northern cities, and it is not contradictory to the prevalence of allergic diseases. Measured indoor temperature and humidity suggested that Chinese houses were little improved on thermal insulation but reduced air change rate in this decade. We proposed the minimum thermal resistance of houses for preventing winter dew condensation from the aspect of mold prevention.
