Description of key information

Determination of 'Ready' Biodegradability: Carbon Dioxide (CO2) Evolution Test (Modified Sturm Test). The study was performed without GLP in a lab which uses to operate under GLP. The study protocol was according to OECD Guideline 301 and EEC method C.4-Cfrom Directive 92/69. No major deviations noted.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The test material was tested for its readily biodegradability in the CO2Evolution Test (Modified Sturm Test) at ca. 39 mg / 2L, corresponding to approx 12 mg TOC / L. The relative degradation values calculated from the measurement of the CO2formation during the test period of 28 days revealed no significant degradation of the test material. The substance was found not readily biodegradable.The toxicity test showed that there is no inhibition of the degradation of sodium acetate by the test substance.
