Factors Affecting Particulate Matter Smaller than 2.5 Microns from Residential Building Construction Activities

Abstract

Nowadays, the construction in Thailand is increasing by leaps and bounds.That’s including to a lot of project of resident and lead to air pollution which effect to health. The air pollution in Northern Thailand always found is particles smaller than 2.5 microns and one of the corse is dust from construction side.This research is to study the activities in construction which generate the P.M 2.5 and analyze the relationship between each activity.The PM 2.5 was measured by digital device before and after activity. In six activity of construction was measured three times and analyzed the relationship between each activity.To study the factors which impact and to prevent the PM 2.5 . In this study,preliminary activity were found.Cutting and sanding generate most PM 2.5than 2.5 microns.
