Abstract |
A theoretical model of the behavior of substances having low water-solubility is presented and discussed with respect to aqueous bioassay. Ultracentrifugal techniques were used in an attempt to study size distributions of Aroclor 1254 aggregates in aqueous emulsions. Results indicate strong adsorption from emulsion by surfaces and a water-solubility at 20C of less than 0.1 microgram/l in distilled water and approximately 40% of that value in water containing 30 g/l NaCl. Implications with regard to aqueous bioassay are discussed. |

A theoretical model of the behavior of substances having low water-solubility is presented and discussed with respect to aqueous bioassay. Ultracentrifugal techniques were used in an attempt to study size distributions of Aroclorª 1254 aggregates in aqueous emulsions. Results indicate strong adsorption from emulsion by surfaces and a water-solubilty at 20ÀC of less than 0.lµg/Á in distilled water and approximately 40% of that value in water containing 30 g/Á NaCl.
