| Summary: | Air pollution is now becoming a common feature in Kuala Lumpur city. It has
assumed an important level to the proportion that the city populace recognises its
presence. The future of air pollution in the city seems to be bleak. From one stand
point, air pollution although dangerous and threatening to the quality of life and
environment, it is a luxurious problem and relatively remote in priority to the general
public. This research is carried out to understand the changes in trend of particulate
matter (PM10) and carbon monoxide (CO) concentration within a set time frame or
limit in the selected monitoring sites which is located in heavily trafficked urban area
of Malaysia which is Kuala Lumpur. Hourly and daily concentration of particulate
matter and carbon monoxide are collected over an 8-month period from January to
August. By using the statistical and graphical analysis, the data will be analysed and
as the results, the variation of concentration for both particulate matter (PM10) and
carbon monoxide (CO) will be define from the analysis. From the research, the
results shows that the ambient level of carbon monoxide was relatively low as
compared to the particulate matter. Based on the analysis, it was found that the
annual average CO value is 2.52 ug/m3 while the annual average PM10 value is 77.64
ug/m3. It was shows that average PM10 levels in Kuala Lumpur network are generally
higher than average CO levels. The concentrations levels of CO were far below the
maximum limit of 30 ppm for one hour averaging time set by the Malaysian
Guidelines. On the other hand, the PM10 mean concentration was higher but still not
exceed the maximum limit 150 ug/m3 for the 24 hour averaging time which also set
by the Malaysian Guidelines.
