Applicant's summary and conclusion

Conclusions:
Elimination (14 d): 33 - 44 %; 24 % with adopted sludge
Elimination (3h): 13 - 15 %; 16 % with adopted sludge
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.

Elimination (14 d): 33 - 44 %; 24 % with adopted sludge

Elimination (3h): 13 - 15 %; 16 % with adopted sludge
