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.
