| Research Abstract |
Five childhood asthma provided daily information on respiratory symptoms and weekly samplers of indoor HONO, NO_2 and O_3 during about three months from September in investigated each year. In the results, a significant difference was not observed in the relationship between NO_2 and asthmatic attack by Mann-Whitney U test. However, a significant difference was observed in the relationship between HONO and asthmatic attack by Mann-Whitney U test (P=0.0013). Moreover, a significant difference was observed in the relationship between HONO and asthmatic attack by multivariate statistics using environment measurement station data. These results suggested that HONO is more correlated with asthmatic attack than NO_2.
