ΠΡΟΣΔΙΟΡΙΣΜΟΣ ΧΛΩΡΙΩΜΕΝΩΝ ΥΔΡΟΓΟΝΑΝΘΡΑΚΩΝ ΣΕ ΟΡΓΑΝΙΣΜΟΥΣ

THE STUDY WAS CARRIED OUT OF THE DETERMINATION IN BODY TISSUES OF CHLORINATED HYDROCARBONS OF ENVIRONMENTAL INTEREST. THESE ARE THE POLYCHLORINATED BIPHENYLS,ALDRIN, P.P'-DDE, HEPTACHLOR O.P'- DDT, P.P'-DDT, P.P'-DDD, A- AND Γ-BHC, HEPTACHLOR EPOXIDE, DIELDRIN AND ENDRIN. THE FOLLOWING PROCEDURE WAS FOUND. 1) REMOVAL OF THE WATER IN VACUO AND AT LOW TEMPERATURE, OR BY BINDING IT TO ANHYDRONSSODIUM SULPHATE. 2) HEXANE EXTRACTION FOR 13 HOURS. 3) REMOVAL OF LIPIDS ON A COLUMN OF ALUMINA HEATED AT 800 C, WITH 5% ADDED WATER. 4) PRELIMINARY SEPARATION OF THE CONSTITUENTS ON A 4X580 MM SILICA GEL COLUMN WITH 16-20% ADDED WATER.THE ELUTION SOLVENT IS FIRST HEXANE, THEN A 20% SOLUTION OF ETHER IN HEXANE. 5) FINAL SEPARATION AND MEASUREMENT OF THE CONCENTRATIONS ON A GAZ CHROMATOGRAPHWITH A 63NI ELECTRON CAPTURE DETECTOR. THE METHOD WAS DISTINGUISHED FOR ITS ACCURACY IN INTERNATIONAL INTERCALIBRATION EXERCISES.
