Factors contributing to air pollution levels using factor analysis
The aims of this study is to determine the major factors and causes of air pollution levels within the four selected Malaysian air monitoring stations. The data were obtained from January 2008 to December 2012. The variables concerned are two meteorological factors (temperature and relative humidity...

| 總結: | The aims of this study is to determine the major factors and causes of air pollution levels within the four selected Malaysian air monitoring stations. The data were obtained from January 2008 to December 2012. The variables concerned are two meteorological factors (temperature and relative humidity) and four air pollutants (CO, PM10, O3 and
NO2). The focus areas comprise of four different localities which are; Perai (S1-
industrial), Shah Alam (S2-urban), Seberang Jaya (S3-suburban) and Jerantut (S4-
control). Two statistical methods were selected to analyze the datasets which are
descriptive statistical analysis and factor analysis. The descriptive statistical analysis
showed that Perai recorded the highest concentrations of CO, O3 and NO2 while
Seberang Jaya recorded the highest concentration of PM10. The results of the factor
analysis showed that there were three factors at Perai, Shah Alam and Jerantut while two
factors at Seberang Jaya. However, the combination of the components in each factors
are different for every station. Nevertheless, it has a significant combination of the
components at Perai where it can be categorized as an Organic Pollution Factor,
Meteorological Factor and Fuel Factor. These results present a guideline to establish
evaluations appropriate to pollution characteristics and classification systems for air
quality monitoring stations in Malaysia. |
