Applicant's summary and conclusion
- Conclusions:
- In these tests performed at ambient laboratory temperature, GC analysis of aqueous solutions showed 65-77% loss of test substance via volatilisation from water over 48h at 95-955 mg/l, and total or near-total total loss over 96h at 1070 mg/l.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
