MATERIALS AND METHODS Solubility Determinations The lack of published solubility values for most of the seven alicyclics neces- sitated the determination of their solubility in distilled water and seawater before we could conduct the toxicity experiments. To determine the solubilities of the seven alicyclics, saturated solutions were prepared by shaking ml of each alicyclic with 220 ml water in a 250 ml separatory funnel for 1 min and letting the mixture settle for 24 h at 20° C. Two 100 ml portions of the saturated water extracts were drained into 125 ml separa- tory funnels; each portion was extracted in succession with three 10 ml aliquots of TF-Freon (trichlorotrifluoroethane) (Reference to trade names does not im- ply endorsement by the National Marine Fisheries Service, NOAA.). Samples were processed as described under Analytical Procedure, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
