	%X In Southeast Asia, during the dry season (August to
October) forest fires in Indonesia emit pollutants into the atmosphere.
For two years during this period, a total of 67 samples of 2.5 μm
particulate matters were collected and analyzed for total mass and
elemental composition with ICP - MS after microwave digestion. A
study of 60 elements measured during these periods suggest that the
concentration of most of elements, even those usually related to
crustal source, are extremely high and unpredictable during the haze
period. In By contrast, trace element concentration in non - haze
months is more stable and covers a lower range. Other unexpected
events and their effects on the findings are discussed.
