Some observations on PM10 fractions levels during and after the 1997 haze episode in Malaysia

N.A. Ramli, . and Warthern P., . and W.H.W. Ibrahim, . and H.A. Aziz, . (2003) Some observations on PM10 fractions levels during and after the 1997 haze episode in Malaysia. [Proceedings Paper]

Measurement of PM10 fractions concentrations were made during the 1997 haze events in Malaysia at five different locations. PM10 was the dominant contributor to pollution during these events. Differences in PM10 fractions at these sites indicate spatial variations in exposure to pollutants at this time. Very high concentrations of PM10 fractions were recorded at all five sites compared to background levels. There were also differences between the Air Pollutant Index API published by the Department of Environment Malaysia and the index calculated on the basis of these data. These differences were related to the localities of the monitoring stations measurement principles limitations of monitoring equipment and vertical position of the measurements. Wet deposition was observed as the most important wash-out factor in clearing the haze. API values remained low following heavy rain and thunderstorms as the rainy season approached.

Abstract

Measurement of PM10 fractions concentrations were made during the 1997 haze events in Malaysia at five different locations. PM10 was the dominant contributor to pollution during these events. Differences in PM10 fractions at these sites indicate spatial variations in exposure to pollutants at this time. Very high concentrations of PM10 fractions were recorded at all five sites compared to background levels. There were also differences between the Air Pollutant Index API published by the Department of Environment Malaysia and the index calculated on the basis of these data. These differences were related to the localities of the monitoring stations measurement principles limitations of monitoring equipment and vertical position of the measurements. Wet deposition was observed as the most important wash-out factor in clearing the haze. API values remained low following heavy rain and thunderstorms as the rainy season approached.
