Abstract


The study evaluate the relationship between the main daily concentrations of criteria air pollutants in urban areas and their associations by using chemometric technique. Data were gathered from the Department of Environmental for three years observations (2011-2013) consisting of 5 major pollutants such as SO2, NO2, O3,CO and PM10 and meteorological parameters such as wind direction, wind speed, temperature and humidity were used. Chemometric technique such asPCA and SPC were used in this study. It can be cocluded that Chemometric technique is meaningful tool for assessment of large and complex air quality data. Besides, it also able to give a clear picture about trends, pattern of major air pollutants and sources identification of pollutants in the study area. This is important for a better management of air quality in the future which able to reduce the possible health and environmental effect.

Keywords: urban air quality; chemometrictechnique; Kota Kinabalu; Sabah.
