Since flame retardant polychlorinated biphenyls (PCBs), which are used for transformer oil, exhibit high
performance in electric insulation, they have been widely used as coolants and lubricants for electrical
facilities such as transformers, condensers, and so on. However, after utilization, depleted PCBs cause
severe environmental loss in water quality as well as soil and air pollution; such effects can be diffused
over a long distance and are known to remain active in the air for approximately 10 days. Moreover,
Animal tests have proven that materials combined with PCBs can negatively affect health in terms of
reduced life expectancy, hyposomia in malignant dermatitis, carcinogenesis, and more. Currently, high
temperature incineration, high temperature melting and chemical processing such as high temperature
thermal processing are utilized as PCB-containing pollutant processing methods. Nonetheless, a study of
PCB-contaminated soil has not been carried out in Korea. In the study herein, an empirical experiment was
conducted in a high temperature incinerator for specified waste processing of PCBs-contaminated soil, and
an environmental performance assessment was undertaken in comparison with specified waste and
processed waste. As a result, the dioxin concentration in the exhaust fumes from the specified waste
processing of PCB-containing soil was 7.4 times higher than processing of target waste without additives,
while exhaust fumes, bottom ash and fly ash exhibited high concentrations in cases where mixed
PCB-contaminated soil were processed for total PCBs.
