Description:
Emissions of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) from stationary combustion sources are of concern because they are carcinogenic and may result in disruption of endocrine systems in human and wildlife populations. PCDDs/Fs are typically present in only minute concentrations in combustor stack gases, which makes sampling and analysis of these compounds extremely expensive and time consuming. Direct, real-time measurement of all PCDD/F isomers of concern is not possible using current technology. However, it is possible to estimate stack PCDD/F concentrations by measuring other indicator (surrogate) compounds that are present in the stack gases at much higher concentrations. These appropriately selected surrogate compounds would be easier to measure than PCDDs/Fs, and could be measured in real-time or near real-time by stack gas monitoring technology that is currently available either commercially or that is in various stages of development. The report discusses the various surrogates that can be used to indicate PCDD/F concentrations, how those surrogates can be measured, and a state-of-the-art assessment of availability and effectiveness of analyzers for measuring those compounds.
