Applicant's summary and conclusion

Conclusions:
Henry's Law constant of C14 AAPB was calculated using EPIWIN v3.20, HENRYWIN v3.10 (bond method). The calculation yielded a value of 3.3 x 10E-18 atm x m³/mole (3.34 x 10E-13 Pa x m³/mole) at 25°C. The calculation of Henry's Law constant according to the equation H=vp/ws and using the EPIWIN estimates for water solubility and vapour pressure resulted in an Henry's Law constant of 6.34 x 10E-19 atm x m³/mole (6.42 x 10E-14 Pa x m³/mole) at 25°C. Based on the results, C14 AAPB can be regarded as non-volatile from aqueous solution. Due to missing information about the applicability of the calculation model in respect to the substance under investigation the results and the conclusions thereof should be treated with care.
