Ethanol fireplaces are getting more popular especially in the colder winter season. In this study concentrations of benzene, formaldehyde, acetaldehyde, carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NO2, NO, NOx) as well as of particles were examined during the combustion of different fuels (liquid and gel-type) in various ethanol fire places. Maximum CO2-concentrations of 7,330 ppm and 6,240 ppm were measured for liquid fuels and gel-type samples, respectively. The NO2 1-hour mean values 230 to 780 mu g/m(3) exceeded the WHO guideline value of 200 mu g/m(3). Formaldehyde concentrations for liquid fuels from 50 to 90 mu g/m(3) lay in the range of AIRs guideline value (100 mg/m(3)), those for gel fuels (120 mu g/m(3)) slightly above. The acetaldehyde concentrations (150 to 570 mu g/m(3)) clearly exceeded the guideline value (100 mu g/m(3), AIR). The use of gel fuels led to benzene concentrations well above the preliminarily defined AIR value of 8 mu g/m(3). High emissions of ultrafine particles were measured during all of the experiments.
