| dc.description.abstract | This study was investigated the composition of aerosol dust particles on Thala Laung Road, Muang District, Songkhla province by collecting dust samples in the air by filtering air through the filter paper and analyzing dust particles by using the Elemental Mapping Analysis with Electron Microscope (SEM) and Electron Particle Analysis Microanalysis - Qualitative Analysis. The results revealed that the size of the particulate matter detected was PM10 and the elements of particle composition were consisted of Carbon (C), Oxygen (O), Sodium (Na), Magnesium (Mg), Aluminum (Al), Silicon Sulfur (S), Chloride (Cl), Potassium (K), Calcium (Ca), Titration (Ti) and Iron (Fe). The amount of collected dust was at 7.72-108.02 microgram per cubic meter (μg/m3). It was lower than the standard level of 120 micrograms per cubic meter (μg/m3), and it did not affect the health. From the constituent particulate matter, the particulate matter is derived from the seawater dust, transport and combustion including the vehicles’ brakes directly caused the aerosol dust with iron and magnesium. Therefore, the analysis of dust particles with this technique can be determined the type of elements. | en_US |
