Polychlorinated Biphenyl Recovery Efficiency from Stack Gas and Ambient Air

Abstract
Polychlorinated biphenyls (PCBs) are now recognized as presenting a severe environmental hazard because of their toxicity and persistence in the environment. High temperature combustion has been shown to be an effective method for destroying these compounds.1 Unfortunately, few facilities are available for their destruction. As part of a feasibility study to convert a liquid-waste incinerator designed for waste fuel to a PCB waste, the sampling efficiency of toluene filled fritted impingers and Chromosorb 102 filled tubes was evaluated.
