Endpoint:
adsorption / desorption: screening
Type of information:
calculation (if not (Q)SAR)
Remarks:
estimated by calculation
Adequacy of study:
disregarded due to major methodological deficiencies
Reliability:
3 (not reliable)
Rationale for reliability incl. deficiencies:
other: calculation is an estimate - validity of model for this substance is unknown. Additionally, the substance decomposes in water. Therefore while estimation by calculation may be possible, it is not realistic.
