摘要：

In the course of evaluating worker exposure during the hot splicing of underground electrical cable, it was discovered that the insulating tape used to make the original joints contained a high percentage (up to 10%) of PCB in the surface varnish. The heating of this PCB by a propane torch flame and molten solder as part of the normal operation of joint breakdown and remake resulted in a composition of airborne fume with a significant fraction (up to 1.3%) of the PCB that was converted to polychlorinated dibenzofurans (PCDF) with the tetra- and penta- chlorinated compounds as the predominant cogeners. No polychlorinated dibenzodioxins were detected. © 1990.
