Description of key information

Long-term toxicity studies testing on fish for DEGDN are not available. Chronic studies performed for TNG were used for read-across:
The LOEC and NOEC for rainbow trout during a 60-d ELS test were 0.06 and 0.03 mg/L (based on a reduction in dry weight). A 28-d ELS with fathead minnow produced a LOEC and NOEC of 0.20 and 0.12 mg/L (based on a reduction in hatching success).
The contact of the DEGDN with the marine water is impossible in normal conditions of use.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater fish:
0.03 mg/L

Additional information

Results of chronic studies on fish for TNG were not used for C&L.

Results of chronic study (60-d ELS test for rainbow trout) for TNG were used for derivation PNEC. Key value for CSA is NOEC = 0.03 mg/L for freshwater fish.
