Abstract |
The report describes risk-driven analysis strategies and a tiered survey approach of analyses that should be useful for building data bases related to other waste combustion processes. The need to characterize hazardous waste incinerator emissions for multiple organic compounds has been steadily increasing for several years. Similar interest is being shown in organic emissions from municipal waste incinerators and sewage sludge incinerators. Seven protocols based on methods published by the EPA were developed and reviewed. The protocols included GC-FID and GC-MS screening for volatile compounds, Soxhlet extraction sample preparation, TCO determination, GC-MS screening for semivolatile compounds, gravimetric determination, and HPLC-UV screening. Application of the proposed scheme to environmental samples in the study was limited. Three extracts of samples obtained from Method 0010 testing of an incinerator under different feed and firing conditions were analyzed by five of the proposed protocols. Thirty-four compounds have been tentatively identified but, more importantly, the protocol methods seem to perform well. |
