Description of key information

The study was performed in year 1999 according to OECD Guideline No. 301D and EU Method C.4 -E and GLP. The test item LZ649 did not reach the pass level of 60 % within two weeks. Therefore LZ649 was considered to have exceeded the ready biodegradability pass level of 60 % ThODNH3 removal within 28 days, but the 14 day window criterium was not met. LZ649 can therefore not in the strict sense be classified as readily biodegradable in this test. However, it may be characterized as inherently and ultimately degradable on the basis of these test results.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
