Abstract

This study analyses dynamic behaviors of indoor ultrafine particles (UFP) emitted from a heated pan containing collected dust. Based on experiments in which a petri dish with naturally collected dust was placed on a hotplate, UFP size and concentration dynamics were analyzed under heat on/off conditions. Results show that deposition loss rates of 0.18-18.75 h-1 are for the heat-off period, while the rates are 0.01-3.11 h-1 for heat-on period. This trend suggests the notable effect of heating status on UFP dynamic behavior. Further research will analyze emission rates and coagulation impact during hotplate heating conditions.
