Abstract

This study aims to determine the influence of meteorological parameters (ambient temperature, relative humidity and wind speed) based on a daily average computation of air pollutants PM10 and NO2 at three selected stations in Malaysia, namely Shah Alam and Johor Bahru on the , and Kuching on the island of Borneo. A three-year (2007-2009) database was statistically analysed using the Pearson Correlation and Multiple Linear Regression methods. The results obtained through these analyses show that at all the three stations, NO2 has a reverse relationship with wind speed, while PM10 has a negative relationship with relative humidity and wind speed, but a positive relationship with ambient temperature. The statistical model of NO2 and PM10 including meteorological parameters highlights that among the three stations, Shah Alam Station which is located near to Kuala Lumpur city centre, is most influenced by meteorological parameters. The coefficients of determination, R2 for Shah Alam station model on NO2 and PM10 are 0.301 and 0.293 respectively. The results from this study could provide some useful input for Malaysian air quality management with respect to an ongoing plan to deal with increasing trend of PM10 and NO2 in the ambient air.
