Título PCB combustion yields dioxin-like substances
Título original PCB-förbränning bildar dioxinliknande substanser [en sueco]
Información bibliográfica 1983, Vol.95, No.1, p.40-43. Illus. 2 ref.
Resumen Attention is drawn to the fact that polychlorinated biphenyls (PCB) may be transformed to polychlorinated dibenzofurans (PCDF) - substances akin in structure to polychlorinated dioxins - by incomplete combustion. The presence of PCDF, and in particular of tetrachlorodibenzofuran, has been proved by wipe tests followed by gas chromatograhpy and mass spectrometry on certains sites of fire or explosion involving transformers or capacitors filled with PCB. Brief descriptions of capacitor-battery fires in Swedish steelworks and results of wipe-test analyses carried out after various fires. Blood monitoring for toxic isomers among the fire-fighting and decontamination personnel yielded negative results. French translation may be obtained from INRS, 30 rue Olivier-Noyer, 75680 Paris Cedex 14, France.
