Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The test substance Methylmagnesium chloride was examined in a ready biodegradability study according OECD Guideline 301F. The test item can be considered to be not ready biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The purpose of this study was to determine the ready biodegradability in a manometric respirometric test over 28 days. The test item was exposed to activated sludge for 28 days. The biodegradation was followed by the oxygen uptake of the microorganisms during exposure. Test method was according to OECD Guidline 301 F (Monometric Respirometry Test). Test substance (127.3 mg/L) was added to culture medium (30 mg SS/L). As a reference item Sodium benzoate was tested simultaneously under the same conditions as the test item, and functioned as a procedure control. Percentage degradation was calculated by dividing the amount of oxygen consumed per mg of test substance by ThOD. Biodegradation of test substance was 3.66% after 28 d treatment. Therefore the test substance is considered not ready biodegradable. The reference item Sodium benzoate was sufficiently degraded to a mean of 76.15 % after 14 days, and to a mean of 78.03 % after 28 days of incubation, based on ThOD.
In the toxicity control containing both, the test item and the reference item, a mean of 27.03% biodegradation was noted.
The percentage biodegradation of the reference and toxicity item confirms the suitability of the used activated sludge inoculum.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
