Abstract

Particulate matter (PM), an inhalable material, is generated from various sources, including building materials. To maintain indoor air quality, it is necessary to analyze harmful substances and establish a method for their remediation. The purpose of this study is to identify the particles generated during the deterioration of building materials and analyze the composition of fine dust particles with respect to the degree of deterioration. The concentration of particles generated was analyzed using an SPS30 PM sensor in the built chamber. PM10 and PM2.5 levels of the maximum of 41.95 mg/m3 and 20.63 mg/m3, respectively, were generated from the tested building materials. The components of the collected PM were carbon, hydrogen, and silicon, among others, which are high-molecular-weight compounds. Particles of size 2.5 µm or less were detected, and the possibility of generating nanoplastics was investigated.

Particle matters and microplastics have been defined as hazardous substances by the World Health Organization. The Particle matters generated indoors are overlooked about the generation of building materials. Building materials are incomplete materials that eventually deteriorate. Wood dust, asbestos, hay dust, and soot were suggested for Particle matters generated from deteriorated building materials. This study emphasizes the need to consider the environmental impact through the recognition of microplastics, a new harmful particle in indoor air quality, through the analysis of the generation of fine particles in building materials.
