Abstract


Air quality played an important role as polluted air quality could harm human health, environment as well as property. Thus, a study of air quality pollutants assessment using chemometrics was performed with the objectives to ensure the air quality data analysis is valid, acceptable and interpreted well. Analysis of PCA, FA, KMO and Bartlett’s test were done on five main air quality pollutants (O3, NO2, SO2, CO and PM10) from all around Malaysia. From the data analysis obtained, the concentrations of air quality pollutants all around Malaysia starting from 2008 to 2011 were acceptable and the most dominant major pollutants had been highlighted. KMO obtained in this study is 0.7760, which show that the results are factor well. While, Bartlett’s test shows that the variables correlated to each other’s. From these tests, air quality data were acceptable for factor analysis.
