ปัจจัยและความสัมพันธ์ของต้นกำเนิดฝุ่นจิ๋วจากกิจกรรมงานก่อสร้าง

Abstract

Construction projects are known as a major source of particulate matter occurrence, which affects construction labors and people in the surrounding area. The objectives of this study are (i) to analyze the particulate matter occurrence from construction activities and (ii) to analyze correlation analysis between factors related to the particulate matter concentrations and particulate matter concentrations. The results show that construction activities which are sources of particulate matter consist of brick wall activity and grinding the cement ceiling activity. The average of particulate matter concentrations ranges from 52 to 201.34 µg/m3. In part of the correlation analysis found that the number of construction works in brick wall activity provides a direct relationship to the particulate matter concentrations, and the quantity of works in grinding the cement ceiling activity provides a direct relationship to the particulate matter concentrations, respectively
