Applicant's summary and conclusion
- Conclusions:
- Bioelimination (14d): 68 %
Bioelimination (3d): 36 % - Executive summary:
The bioelimination potential of the substance was assayed following the Hoechst Method No 4, November 1973. Bioelimination was recorded at 14 days and after 3 hours of exposure.
Bioelimination (14d): 68 %
Bioelimination (3d): 36 %
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
