Biodegradation in water:
inherently biodegradable, not fulfilling specific criteria

Additional information

This multi-constituent substance was tested for ready biodegradation and inherent biodegradation. The test for ready biodegradation demonstrated that the test substance is not ready biodegradable. A test for inherent biodegradation demonstrated that the test substance is inherently biodegradable, not fulfilling specific criteria. The test substance did not attain greater than 70% biodegradation within 14 days. Therefore the rate constant for elimination in sewage treatment plant is 0 k (h-1).
