Particle Emission Characteristics of Office Printers

Nowadays there is little doubt as to the importance of Indoor Air Quality (IAQ), since modern society tends to spend the vast majority of time in various types of indoor environments. In addition to the penetration of pollutants from outdoor air, most indoor built environments contain air pollution sources that release fibers, particles, organic vapors, or inorganic gases. To address this need, this study aimed to simultaneously monitor sub micrometer particle number concentration for 48 h, in a large open-plan office, as well as outdoors, to assess the potential impact of indoor activities on indoor particle concentrations; measure concentrations of sub micrometer particles in the immediate vicinity of operating printers in a multilevel office building; measure particle characteristics.
