| 520 | 3 |a"This report describes a quantification method for toxaphene in water as well as an evaluation of various methods for the extraction of toxaphene spikes from a heavily contaminated sediment. The toxaphene quantitation from water gave acceptable recoveries (>801). Using several extraction and cleanup procedures of toxaphene in sediment at the l0-7 g/g level (toxaphene to sediment), the recovery of toxaphene was less than 70%. Using solvents of varying polarity for extraction and column chromatography, different methods of extraction, and chromatography support materials with different activities did not enhance the recoveries"--Abstract. |
