Drill down PM2.5 Phitsanulok is not just dust, it's the complexity of its origin and season.

The Naresuan University Graduate School presented the results of a postgraduate study studying PM2.5 in Phitsanulok province by comparing the forest area (Kwai Noi National Park) with the urban area (Borom Trailok Road, Nakhon Phitsanulok Municipality) in both dry and rainy season. Through the analysis of the concentration, morphology and elemental composition of dust particles, PM2.5 was found to have nine different forms and elemental elements linked to many sources, including biomass combustion, soil dust, metal erosion, and agricultural activities. The study indicated that PM2.5 managementwhich effectively must consider both the amount of particle shape and elemental elements to identify the true origin.
