A MODIFIED MILLS EXTRACTION METHOD WAS COUPLED WITH A THIN-LAYER CHROMATOGRAPHIC CONFIRMATION AND A GAS CHROMATOGRAPHIC QUANTIFICATION OF ORGANOCHLORINE PESTICIDE RESIDUES IN COMMERCIALLY CAUGHT FISH FROM 78 LOCATIONS IN 68 CENTRAL CANADIAN LAKES AND RIVERS. ONLY A FEW OF THESE WATER YIELDED FISH WITH APPRECIABLE CONCENTRATIONS OF DDT AND ITS ANALOGS (GREATER THAN 1 PPM), AND IN ONLY A FEW CASES DID THE CONCENTRATIONS EXCEED THE MAXIMUM PERMISSIBLE LEVEL OF 5 PPM. OF THE OTHER ORGANOCHLORINE PESTICIDES COMMONLY USED, NAMELY LINDANE, ALDRIN, HEPTACHLOR, HEPTACHLOR EPOXIDE, ENDRIN, DIELDRIN, AND CHLORDANE, ONLY DIELDRIN WAS FOUND AT SIGNIFICANT LEVELS IN A NUMBER OF SAMPLES, BUT THESE AMOUNTS WERE STILL BELOW THE MAXIMUM PERMISSIBLE LEVEL. TRACE AMOUNTS OF LINDANE WERE FOUND IN SOME SAMPLES. THE PRESENCE OF POLYCHLORINATED BIPHENYLS (PCB'S) WAS NOTED IN SAMPLES FROM THE GREAT LAKES AND THE SOUTH END OF LAKE WINNIPEG. PCB'S WERE SEPARATED FROM DDE ON ALUMINUM OXIDE G (TYPE E) PLATES RUN IN A TRIETHYLAMINE-HEXANE SOLVENT SYSTEM. (MACKAN-BATTELLE)
