Abstract
A simple measurement method for medium and low volatile organic halogens (MLVOX) in flue gas at municipal waste incinerators (MWIs) and its utilization are described. 10~40L amounts of flue gas were sampled at 11 stoker-type MWIs and concentrations of organic chlorine and organic bromine were measured with barrier-discharge radiofrequency helium plasma. It was found that LVOCl gave a higher correlation to total dioxins than MVOCl. However, memory effect is thought to explain the difference in the correlating equation. Moreover, LVOCl-TEQ correlated less than LVOCl-total dioxins, because LVOCl quantified the amount of organic chlorine independent from the structure-governed toxicity. In addition, this method can be utilized to facilitate monitoring the concentrations of organic halogen in flue gas, operating gas treatment devices and observing the status of de novo synthesis.
