Description of key information

Activate sludge (adaptation not specified) was used as inoculum at a

concentration of 30 mg/L; the concentration of 1,3-dichlorobenzene was of 100 mg/L. Ready biodegradability was measured in terms of BOD; no biodegradation was observed after four weeks (28 days) of incubation. Under anaerobic conditions, 77% primary degradation (loss of chlorine) was observed within 32 days.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
