In this study, it was aimed to evaluate the removal efficiency of Sigma 82 species of PCB, with the addition of H2O2 at certain doses (1%, 10% and 20%) in UVA applications to removal ofPCB pollution from soil. Soil samples were exposed to UV rays at 18. and 30 degrees C for 24 hours and PCB removal applications were performed.. During UVA applications, with the use of additive, the total removal efficiency at 18 degrees C was 82%, while it reached 95% at 30 degrees C. The most effective (95% PCB removal) dose was determined as 10% H2O2 at 30 degrees C. On the basis of PCB species, the removal of heavy chlorinated species was found to be high. When all applications for Dutch Sigma(7) PCB species were examined, over 90% removal efficiencies were obtained. The cancer risk probability of three main exposure (ingestion, dermal, inhalation) of PCB isomers were determined. Furthermore, carcinogenic potential risk and toxicity values of PCB species were determined. As a result of the cancer risk analysis, it was determined that the soil samples taken from the vicinity of the industrial zone in Bursa were in the "very low risk "group and there was no health risk in terms of toxicity.
