Chlorobenzenes, Chlorophenols, PAHs and Low Chlorinated Dioxin/Furan as Post-Boiler Toxicity Indicators in Municipal Solid Waste Incinerators
Numerous research studies have been conducted to establish indicator compounds for fast and less costly predictive monitoring of polychlorinated dibenzo-p-dioxin and furan (PCDD/F) toxic equivalent concentrations (TEQs). Many studies have shown that chlorobenzenes and chlorophenols had a good correlation with TEQ, suggesting that these compounds could be used as PCDD/F TEQ indicators. Good correlation results were reported between some low mono-to tri-chlorinated PCDD/F isomers and and TEQ. Given that indicator/TEQ relationships may be plant- and location (temperature) specific, past eforts to determine indicators using combined data from multiple facilities and multiple locations within a single facility that are limited in number of samples and species may be insufficient to determine robust indicators. The objective of this study is to determine indicator compounds based on intra-facility measurements under different operating conditions and to examine the effect of sampling position on potential indicator/TEQ relationships. An expanded indicator set, including chlorobenzenes, chlorophenols, polyaromatic hydrocarbons, and low chlorinated dioxin/furan were analyzed to identify the relationship between these compounds and TEQ.
