Physical and chemical characterization of indoor aerosols resulting from the use of tap water in portable home humidifiers.
Indoor PM10 concentrations exceeding 150 mug/m3 were observed when ultrasonic and impeller humidifiers, charged with tap water, were operated under whole-house conditions.
Microscopic analysis confirmed that the resulting particles were predominantly submicron spheres with mineral composition reflecting that of the charging water.
Elements measured in high concentrations were uniformly present as soluble salts in both the fine and coarse particles, with small differences observed between the ultrasonic and impeller humidifier-generated aerosols.
