Description of key information

The ready biodegradability of Sec Butyl Quinoline was investigated in a study conducted in accordance with OECD Guideline 301F (Manometric Respirometry Test) and GLP principles. The study was performed at 1 test concentration of the test substance (100 mg/L) plus a inoculum blank and a toxicity control. A reference substance (sodium benzoate) was also tested. The test substance undergoes no biodegradation after 28 days (0 % after 31 days) and it was not toxic to the inoculum. The validity criteria of the test guideline were fulfilled despite the pH being above the guideline limit of 8.5 (max pH variation <1.5) which was not considered to affect the outcome of the present study. In conclusion, the substance is not readily biodegradable under the conditions of this test.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
