Abstract
Haze events occurred in Malaysia almost every year since more than two decades. These events
were usually accompanied with high PM10 concentrations which can last longer than three days.
This study attempt to characterized the years with haze events systematically by fitting the
monitoring records into three distributions that were reported to have dealt with extreme events
especially those related to air pollutions studies. These distributions plotted were then utilized to
established exceedences of Malaysian Air Quality Guidelines and prevalence of high PM10
concentrations. Worst high particulate events were identified in 1997 as compared to 2004 and
2005 in most of the selected study sites. Weather parameters were expected to have some
influence on the concentrations of PM10. PrevJous hour concentrations, wind speed and
temperature were proven to have great influence on predicted PM10 concentrations. A workable
framework was proposed from this research to reduce the incidents of exceedences which requires
close cooperation between multiple levels of governance and enforcements. In addition, efforts on
capacity building and specific skill training should be given ample attentions. Finally, education,
awareness and willingness to change at all walk of life are paramount in ensuring environment
provides better air quality.
