Results and discussion
Any other information on results incl. tables
Rate constants can NOT be calculated for phosphite chemical structures (HYDROWIN v. 2.0).
Applicant's summary and conclusion
- Validity criteria fulfilled:
- no
- Conclusions:
- Rate constants can NOT be calculated for this structure (HYDROWIN v. 2.0).
- Executive summary:
While the phototranformation in water cannot be determined for this substance, the rapid direct hydrolysis in water of these substances is likely to be the dominant environmental fate characteristic of this substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
