Description of key information

Toxicity to microorganisms of phosphinicocarboxylates, sodium salts was assessed using the method descrbied in OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test).

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
200 mg/L

Additional information

Although the study report (Desmares-Koopmans, 2002) indicates that the EC50 is > 200 mg/L, no significant effects on microbial respiration were observed at this concentration (the highest concentration tested). This value of 200 mg/L was therefore treated as a NOEC for this endpoint.
