Abstract
ABSTRACT
2,3,7,8-Tetrachlorodibenzodioxin toxicity equivalents (I-TE) were closely correlated with the concentrations of other chloroaromatic compounds like pentachlorophenol, pentachlorobenzene, and hexachlorobenzene in the flue gas of three waste incinerators. To predict I-TE from these indicator parameters, regression equations were established for different sampling points of three hazardous waste incinerators. The sampling points were located in the boiler, directly upstream and downstream of the electrostatic precipitator, and downstream of the wet scrubber. Typically, the slopes of the regression lines were similar for the different incinerators at a given sampling point, but the intercepts were different. These findings indicate the possibility of transferring part of the regression results (the values of the slope) from one incinerator to another. The intercept of the regression line, which can be different, can then be determined with only a few simultaneous measurements of I-TE and the indicator compound.
