Pesticide Monitoring Study. Evaluation of Silicic Acid Column Pesticide/Polychlorinated Biphenyl Separation Procedure:Recovery and Elution Patterns of 24Pesticides and Pesticide Metabolites and Two Polychlorinated Biphenyls.

摘要

This report presents silicic acid column recovery and elution characteristics for 24 pesticides and pesticide metabolites and two polychlorinated biphenyls. The average percent recoveries for all except a few compounds studied were essentially quantitative. The average percent relative standard deviation of the procedure for all but a few compounds studied was within 10 percent. All the compounds studied except for toxaphene, Aroclor 1260, and technical chlordane eluted in only one fraction. An in-depth discussion of the elution characteristics and the quantitation techniques for the above three compounds is presented.
