Description of key information

With high probability acutely not harmful to aquatic algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L
EC10 or NOEC for freshwater algae:
500 mg/L

Additional information

In a 96-h GLP static algal toxicity study with sodium formate (CAS 141-53-7), the 72-h NOEC (growth rate) was determined to be 500 mg/L (Hoechst Celanese, 1990; statistical re-evaluation: ECT, 2010). The 72-h ErC20 was 807 mg/L and the 72 -h ErC50 was > 1000 mg/L. Test item concentrations were analytically verified.
