Description of key information

A guideline compliant algal growth inhibition study exists for DETDA.  The ErC50 and ErC10 values are 104 mg/L and 54 mg/L, respectively.  The study LOELr was 100 mg/L, and the study NOELr was 32 mg/L.
The classification and labelling (R50) and the derivation of the PNEC is driven by the experimantal result of the acute daphnia study.

Key value for chemical safety assessment

EC50 for freshwater algae:
104 mg/L
EC10 or NOEC for freshwater algae:
54 mg/L
