PM 10 concentration between 50 – 54 µg/m 3 . Next, areas of Sentul show about 47 – 50 µg/m 3
of PM 10 concentrations during the Northeast Monsoon.

The dispersion PM 10 concentration of mean during Northeast monsoon is similar with the
dispersion of mean PM 10 concentration along the year 2004 till 2008. During the wet season
or Northeast monsoon, the maximum of PM 10 concentration can be seen are the averaging of
the PM 10 concentration. Meanwhile, the mean of the PM 10 concentration dispersion in Kuala
Lumpur during Southwest Monsoon year 2004 until 2008 is shows in Figure 15. Averages of
the dispersion of PM 10 concentrations during Southwest Monsoon from year 2004 until 2008
are in the range of 52 – 60 µg/m 3 . Areas of Cheras, Sungai Besi, and Damansara show the
highest PM 10 concentration between 57 – 60 µg/m 3 . Next, areas of Ampang show about 55 –
57 µg/m 3 of PM 10 concentrations. As well as areas of Sentul, the PM 10 concentrations are in
the range of 52 – 55 µg/m 3 . The averaging of the PM 10 concentration during Southwest
monsoon or dry season is higher than the overall averaging PM 10 concentration from year
2004 until 2008. This shows that Kuala Lumpur had a higher pollution during the dry
season.

Monsoon from year 2004 until 2008. Maximum of the dispersion of PM 10 concentrations
