Description of key information

Results 
72 h - ErC50 = 110.48 mg/L (IC = [79.24 - 154.05] mg/L)
72 h - ErC10 = 18.45 mg/L (IC = 13.6 - 25.02 mg/L)
NOEC (growth rate) = 3.10 mg/L
LOEC (growth rate) = 9.80 mg/L

Key value for chemical safety assessment

EC50/LC50 for freshwater algae:
110.48 mg/L
EC10, LC10 or NOEC for freshwater algae:
18.45 mg/L

Additional information

The 1,2-diethoxybenzene was not considered as dangerous for unicellular algae with an 72h ECr50 > 100 mg/L. The study was conducted according to OECD guideline 201 and EU Method C3 and GLP compliance.
