other information
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a (Q)SAR model, with limited documentation / justification, but validity of model and reliability of prediction considered adequate based on a generally acknowledged source

Applicant's summary and conclusion

Conclusions:
As Henry's law constant is well below 3*10 E-2 Pa*m³/mol volatization from water into air is considered negligible.
