Description of key information

PB-370, under the conditions of the test is considered to be non-readily biodegradable

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Ready biodegrability testing of PB-370 has been carried out using Modified Strum Test.

The study was extended to 43 days since the biodegradation curve of PB-370 had not clearly plateau after 28 days.

The percentage of biodegradation values of PB-370 after 39 days for 17 mg OC/L and 43 days for 33 mg OC/L, were 37 and 38% respectively.

An inhibition test showed that PB-370 was not inhibitory to bacteria at a concentration of 33 mg OC/L.

Under the test conditions PB-370 is considered to be non-readily biodegradable
