摘要: Biomass burning is one of the main sources air pollution in South East Asia, predominantly during dry period between June and October each year. Sumatra Kalimantan, Indonesia, have been identified as regions connected to biomass due their involvement agricultural activities. In Sumatra, Province Riau has always found had highest number hotspots haze episodes. This study aims determine concentration five major pollutants (PM 10 , SO 2 NO CO O 3 ) Riau, for 2006 2007. It will also correlate level recorded, using hotspot information system introduced by Malaysian Centre Remote Sensing (MACRES). Overall, recorded was increase with hotspots. Nevertheless, only PM a episode significantly different when compared its non-haze conditions. fact, August 2006, more than 20% from normal concentration. The dispersion pattern, simulated Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT), showed that distribution greatly influenced wind direction. Furthermore, particles capacity reach Peninsular Malaysia within 42 hours emission point consequence West monsoon.
