ปัจจัยที่มีผลต่อค่าฝุ่นละอองที่มีขนาดเล็กกว่า 2.5 ไมครอน จากกิจกรรมในงานก่อสร้างอาคารบ้านพักอาศัย

Abstract

The construction pollution is mixing from particles matter in both 10 microns (PM 10) and 2.5 microns (PM 2.5). The research studies factors affecting particle matters from construction focusing only on PM 2.5 from several construction activities. HandheldPM 2.5 sensors were used measuring at differing distances, time delays, temparature, and humidity from six construction activities. The testing activities were tiles cutting, ceiling finishing, masonry, concrete chiselling, floor finishing, and floor cleaning and dusting. The activity contributed most PM 2.5 were tile cutting. Distances from the construction spots and time delays activities provides inverse relationship to the concentration of the PM 2.5. Only concrete chisel provides concentration of PM 2.5 after the long period of time.
