ABSTRACT
Urban developments, land use patterns and activities not only influence the volume of emissions into the ambient air environment but also affect the ability of the urban ecosystem to purify the air. Therefore, urbanisation affects the quality of air in urban areas. However, urban air quality is also affected by global, regional or trans-boundary pollutants. The objectives of this paper are to understand the trend of air quality level and urban growth in Kuala Lumpur city (KL), and examine the relationship between these variables. Results of analysis show a significant and strong relationship between the number of unhealthy/hazardous days and urban land uses. The finding is contrary to the argument that the high concentration of air pollutants (unhealthy level) in the Malaysian city is contributed by the forest fire in a neighbouring country (haze).
