DIOXIN EMISSIONS FROM WASTE INCINERATORS - CHLORINATED BENZENES AND CHLORINATED BIPHENYLS AS INDICATOR PARAMETERS FOR TOXICITY EQUIVALENTS OF CHLORINATED DIBENZODIOXINS AND DIBENZOFURANS

Concentrations of polychlorinated dibenzodioxins (PCDD), polychlorinat ed dibenzofurans (PCDF), chlorobenzenes, chlorophenols, polychlorinate d biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAH) were meas ured in the stack gas of a hazardous waste incinerator. Toxicity equiv alents (I-TE) were calculated according to the international toxicity equivalency factor scheme. I-TE were significantly correlated with chl orobenzenes and PCB. These classes of compounds can therefore be used as indicator parameters from which I-TE values may be estimated. The m ost accurate estimates were made using pentachlorobenzene or heptachlo robiphenyl.
