P articulate and Gaseous Air Pollutants Measured in Malaysia during the 1997 Haze Episode A contribution to subproject AEROSOL K Granby\ G GeernaeiV, P. Wahlin\ F Palmgren C.P.

Box 358, DK-4000 Roskilde, Denmark ^Malaysian Meteorological Service, Jalan Sultan, 46667 Petaling Jay a, Malaysia In August-October 1997 the aerosol haze in Malaysia was the worst recorded in recent history. Measurements made during the haze episode (25th August- nth September) of some gaseous and particulate components known to be enriched in biomass burning impacted air masses showed results for e.g. formic acid (0-26 ppb), acetic acid (0-28 ppb) and oxalic acid (0-2.3 ng/m^) among the highest concentrations reported in ambient air. The aerosol components were correlated to TSP (total suspended particulates) which peaked later in September indicating t
