summary
A clean-up procedure for the isomer-specific analysis of polychlorinated dibenzodioxins (PCDDs) and dibenzofurans (PCDFs) in oil extracts from water leachate of a hazardous waste landfill is described. The samples were chromatographed on Alumina B-Super I, silica gel combined with silica gel/44% conc. H2SO4, and on Bio- Beads S-X3. Separation of 2,3,7,8-tetra-CDD and final sample purification were performed on Alumina B-Super I (micro column). Among the 2,3,7,8-tetra- to hexa-CDDs/CDFs, 2,3,7,8-TCDD was by far the most abundant isomer, determined at a mean concentration of 70,5 ppb. Industrial wastes from 2,4,5-trichlorophenol production are assumed to be the main source for this high concentration. From the isomer distribution pattern of the hepta-CDFs, pentachlorophenol can be considered as source of the higher chlorinated PCDDs/PCDFs.
