Description:
The overall objective of this research project was to develop a unified analytical approach for use in quantifying ppt levels of tetrachlorodibenzo-p-dioxins (TCDD's) in various chemical wastes. Waste samples from plants manufacturing trichlorophenol, pentachlorophenol, and hexachlorophene, and from processing wood preservatives were provided by the EPA. The extraction procedure developed for isolating the TCDD's from the various types of sample matrices is fully described. Analysis was accomplished using highly specific and sensitive coupled gas chromatographic-mass spectrometric (GC-MS) methods. Both low and high resolution MS techniques were employed. This methodology is also described in detail. The procedures presented in this report were acceptable for most of the industrial process samples provided.
