Applicant's summary and conclusion

Conclusions:
Bioelimination (14d): 16 - 34 %
Bioelimination (3d): 15 - 50 %
Executive summary:

The bioelimination potential of the substance was assayed following the Static method, Hoechst No 4, November 1973. Bioelimination was recorded at 14 days and after 3 hours of exposure.

Bioelimination (14d): 16 - 34 %

Bioelimination (3d): 15 - 50 %
