| Summary: | 碩士 === 東海大學 === 環境科學系 === 84 === This study has analyzed and compared 23 air quality
indices used in the United States,Canada,Mainland China, Japan
and Taiwan. A New Air Quality Index（NAQI）is proposed ,using an
Entropy Function which avoids the potential problems of
ambiguity and eclipse.Data on the 5 most important air
pollutants were collected from air quality monitoring stations
in the Taichung area.Without having precise epidemiology data,
the weekly absenteeism rate among school children was tested for
its correlation with air pollutants,using NAQI and Pollutant
Standards Index（PSI）.Only SO2 level showed significant
correlation（P＜0.05） with absenteeism.There was no difference
in sigaificance of this correlation using these two indices.Key
words：Urban Air Quality，New Air Quality Index（NAQI），
Pollutant Standards Index（PSI），Entropy Function
