Beschreibungen/Notizen

• Fly ash was sampled with a standard high-volume sampler at temperatures of 110-125 degree C after the electrostatic precipitator of a 300-MW sub(t) pulverized coal-fired power plant to investigate short-term variations in the mutagenicity of fly ash emissions. Fifty-eight 1-2-h samples were collected during 9 days. Organics were extracted with acetone and analyzed by the Ames test with Salmonella typhimurium) strain TA100 and S9 activation. Other measured parameters were CO sub(2), SO sub(2), NO, CO, and particulate emissions, steam load, and sampling temperature. The mutagenicity of the fly ash (rev/mg/rev = revertants) did not correlate with any of the measured parameters.
