WebA lower Kow indicates a preference for water over oily solvents; a higher Kow means it is more lipid-loving than water loving (“lipophilic”). Kow is useful because it predicts the … WebHowever, at very high log Kow (>6), a decreasing relationship between the two parameters is observed. The aquatic BCF of a substance is probably lower than 2000 L/kg if the calculated log Kow is higher than 10 (i.e. a log Kow >10 is taken as an indicator for showing reduced bioconcentration).
WebMar 6, 2024 · The 1-octanol-water partition coefficient (Kow) is the equilibrium ratio of the concentration of a material in 1-octanol to the concentration of that material in water in an immiscible mixture of 1-octanol and water. The published values of log10 of Kow, i.e. Log(Kow), range from about -4 for saccharides to +10 for phthalate esters. WebKow ≥ 4 provided log Kow is an appropriate descriptor for the bioaccumulation potential of the substance. Measured log Kow values take precedence over estimated values and measured BCF values take precedence over log Kow values. Note 5. “No acute toxicity” is taken to mean that the L(E)C-50 is above the water solubility. Also for
