| Abstract: | This communication describes a simple isolation/extraction procedure for fish and sediment samples based on acid digestion, gel permeation chromatography, trisodium phosphate treatment, micro-alumina chromatography and carbon fibre colum chromatography. The cleaned extracts are analysed for tetrachloro dibenzo-p-dioxins using GC-ECD screening and HRGC-MS (multiple ion dection) confirmation. |
