Abstract

The paper describes a method of 2,3,7,8-TCDD determination in soils heavily contaminated with organic compounds ( the soil from areas of plants producing pesticides, chlorophenols, etc.). The procedure is based on a sample extraction with a hexane-acetone mixture, cleaning of the extract by washing with potassium hydroxide and sulfuric acid solution and by liquid chromatography on a multilayer modified silica column and aluminia columns, and on GC/MS determination using a labelled internal standard (<sup>13</sup>C-2,3,7,8-TCDD). The determination limit is 10 ppt and the average recovery 55%.
