Results and discussion

Applicant's summary and conclusion

Conclusions:
The bioelimination based on TOC was found to be 33 % in 3 hours and 46 % in 14 days.
Executive summary:

The bioelimination of the test item was evaluated in a test based on the determination of total organic carbon (TOC), according to an internal method. Two test item concentrations were tested and the percentage elimination was evaluated over a 14-day study period.

At a concentration of 800 mg test item/l (120 mg TOC/l), the test item was degraded by 26 to 37 %. At a concentration of 2700 mg test item/l (400 mg TOC/l), the test item was degraded by 31 to 39 %. The bioelimination based on TOC was found to be 33 % in 3 hours and 46 % in 14 days.
