Analysis of polychlorinated dibenzofurans and polychlorinated dibenzo-p-dioxins in transformers and capacitors: Volume 1, PCDF/PCDD at New York State Health Department: Final report
Seven samples of in-service utility fluids were analyzed for nineteen different polychlorinated dibenzofuran (PCDF) and polychlorinated dibenzo-p-dioxin (PCDD) compounds. Generated calibration plots for eight different individual compounds were linear over four orders of magnitude concentrations. Analyses in triplicate provided some insight on reproducibility of method. Spiked samples were analyzed with an average error of 28.9%, indicating that for the chosen analytes in this type of oily matrix, the method was quite reproducible and accurate. The relative standard deviation was less than 30% for more than 92% of the analyte determinations. The study showed that the samples of in-service utility fluids have considerably different PCDF-PCDD profiles. Maximum concentrations of tetrachlorodibenzofuran (TCDF) and tetrachlorodibenzo-p-dioxin (TCDD) were 1.2 and 0.001 mg/kg, respectively. Maximum concentrations of octachlorodibenzofuran (OCDF) and octachlorodibenzo-p-dioxin (OCDD) were 40 and 0.02 mg/kg, respectively. And two fluids contained barely detectable quantities of any PCDD or PCDF (maximum concentration: 0.003 mg/kg). 18 refs., 6 figs., 2 tabs.
