Some people argue that abortion is also infanticide. In some cases abortion is needed to save the pregnant mother because of severe medical problems that would result in the death of the pregnant mother, but in other cases abortion has been used as an elective surgery to terminate an unwanted pregnancy.
Definition: The octanol/water partition coefficient (Kow) is defined as the ratio of a chemical's concentration in the octanol phase to its concentration in the aqueous phase of a two-phase octanol/water system. Kow = Concentration in octanol phase / Concentration in aqueous phase. Values of Kow are thus, unitless. The parameter is measured using low solute concentrations, where Kow is a very weak function of solute concentration. Values of Kow are usually measured at room temperature (20 or 25'C. The effect of temperature on Kow is not great-usually on the order of 0.001 to 0.01 Iog Kow units per degree-and may be either positive or negative.
BPA has moderately high water solubility, about 120 mg/liter. In addition, this chemical has a low vapor pressure of about 5.32 to 5 Pascals (Groshart C Okkerman P and Pinjenburg A 2001). A standard coefficient for various environmental substances is the octanol-water partition coefficient (Kow).This ratio is the concentration of a chemical in octanol, commonly used as an organic solvent, and water at equilibrium (United States Geological Survey 2008).The log Kow value for BPA varies from 2.2 to 3.4 (see figure A:3 for additional properties).Consequently, these characteristics of bisphenol-A give it the propensity to partition in water, and the rate of evaporation from soil and water is low. standard coefficient for various environmental substances is the octanol-water partition coefficient (Kow). This ratio is the concentration of a chemical in octanol, commonly used as an organic solvent, and water at equilibrium (United States Geological Survey 2008).
