Environmental fate determining physical properties including their temperature dependence for five nitro musks and for seven polycyclic musks were estimated. The properties evaluated were vapor pressure in a solid and liquid state (PS and PL), solubility in water (S), Henry´s law coefficient (H = PL/S) and log octanol-water partition coefficient (log KOW). Gas chromatography for starting values of vapor pressure estimation and HPLC experiments at 5-20 degree Celsius for comparison of the theoretical versus experimental solubilities in water were performed. The values of temperature (T) dependence coefficients (Ai and Bi) in equations: log (Property)i = Ai - Bi / T were determined. Values of properties were compared with literature-based data, and an example of their use in environmental hazard estimation by fate modeling was given. | | Keywords: environmental fate modeling; GC; Henry´s law; HPLC; nitro musks; octanol-water partition; polycyclic musks; solubility; synthetic musks; temperature; thermodynamics; vapor pressure |
