Characterization of Emissions from Heaters Burning Leaded Diesel Fuel in Unvented Tents
Abstract
The human exposure to aerosols from unvented heaters in tents was simulated, so that the contribution of this exposure to the Gulf War Syndrome could be estimated. Exposures to particulate matter and combustion gases (CO, NO, and SO2) were estimated with three types of portable kerosene heaters and three fuels. The airborne concentration was also monitored continuously with a real-time monitor. The aerodynamic particle size distribution measured by a cascade impactor showed a major peak between 0.1 - 1 micrometers. The air exchange rate ranged from 1 to 3.4/hr when the tent doors were open and closed. The air exchange rate-and the type-of fuel and heater were very important factors in determining the pollutant concentrations inside the tent. Chemical analyses showed that major species in the particles were sulfate, nitrates, ammonium and elemental and organic carbon.
