Abstract

The aim of this study is to determine both temporal and spatial particulate matter (PM10) concentration distribution at selected region in Klang Valley, Malaysia for ten years’ dataset according to monsoon seasons. Air quality data used in this study provided by Malaysia Department of Environment (DOE). A total of 14,608 daily mean of PM10 and meteorological parameters (humidity, temperature and wind direction) data from 2006 to 2015 at eight Continuous Air Quality Monitoring (CAQM) stations in Klang Valley are used in this study. Statistical Package for the Social Sciences (SPSS) and ArcGIS 10.4 software are used in this study to apply the descriptive statistical and spatial trend of this PM10 concentration. The result showed that increasing of PM10 concentration are being observed in Southwest monsoon and decreasing during Northeast monsoon. The Ordinary Kriging distribution map shows that the station located at urban and industrial area will have higher PM10 concentration as compared to the station that is located in the rural area. The spatial interpolation method, Ordinary Kriging was used to interpolate the PM10 concentration outside the station’s range.
