| Abstract: | Summary Polychlorinated Dibenzo-p-dioxins (PCDD) and Dibenzofurans (PCDF) in fly ash samples from coalburning power plants in Greece have been determined by high resolution gas chromatography combined with mass spectrometric detection (HRGC-MS) applying the isotopic dilution technique. Concentrations of PCDFs were 20 to 600 fold higher than for PCDDs. The concentrations of PCDDs and PCDFs were in the range of 11–62 and 1254–7180 pg/g respectively. Fly ashes from coal-burning power plants were found to be potential sources of PCDFs. |
