Abstract |
The paper gives an overview of generalized analytical procedures for determining designated principal organic hazardous constituents (POHCs) in combustion products; it also gives some examples of the techniques used for compounds such as 2,3,7,8-tetrachlorodibenzodioxin, selenourea, and several organo-arsenicals. Emissions from hazardous-waste combustion must be monitored to determine the destruction removal efficiency (DRE) for each designated POHC. Analytical methods for more than 150 POHCs have been reviewed. A generalized HRGC/LRMS method to determine volatile, thermally stable POHCs has been developed. A method based on HPLC with UV detection has also been developed to provide an alternative for determining nonvolatile or thermally labile compounds. The generalized methods are applicable to many compounds, but specific POHCs may require variations in GC/MS or HPLC procedures. Inclusion in the paper does not mean that the sampling or analysis method is an official EPA method. Official test methods for hazardous waste related programs are published in SW-846, Test Methods for Evaluating Solid Waste, as well as in the Federal Register. |
