Description of key information
Ready Biodegradability test.
Testing facility: Bayer AG, Leverkusen
Study no. 1053 A/00 R performed on January 22, 2001
The study was conducted under GLP in accordance with the Council Directive 92/69/EEC Method C.4-D (Manometric Respirometry Test".. This method is inall essential parts identical with OECD Guideline 301F.
The registrant has a letter of access.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
A solution of BCI in a mineral medium was inoculated and incubated for 28d under aerobic conditions. During this period the ready biodegradability is determined.
BCI showed
0% degradation after 2 days
3% degradation after 8 and 10 days
6% degradation after 14 days
7% degradation after 16 days
9% degradation after 20 and 22 days
11% degradation after 24 days
12% degradation after 28 days
The reference compounnd showed 85% degradation after 14 days.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
