In a single set of experiments we have investigated the effect of ozon
e on the radiation chemistry of PCB 155 in isooctane. The results sugg
est that PCB decomposition in this oil-like alkane solution is inhibit
ed by ozone, probably due to the ozone-electron capture reaction. Hydr
oxyl radicals generated by ozone-electron capture apparently do not pl
ay a role in PCB decomposition in this matrix. Copyright (C) 1996 Else
