Gas Chromatographic Measurement of Toxaphene in Milk, Fat, Blood, and Alfalfa Hay
The need for a sensitive and reproducible method for determination of submicrogram quantities of toxaphene in food, forage crops, milk, and meat has become apparent with the widespread use of this pesticide. Graupner and Dunn (1) originally described a spectrophotometric procedure that could determine toxaphene in the 20 to 100 μg range. Extensive cleanup procedures were employed before analysis.
