Description of key information

Reliable short-term toxicity tests results are available on freshwater fish (Brachydanio rerio), aquatic invertebrates (Daphnia magna) and algae (Pseudokirchneriella subcapitata) for the registered substance. The relevant short-term values are:

Fish: 96h-LC50 > 100 mg/L (analytically confirmed nominal concentration)

Aquatic invertebrates: 48h-EC50 > 100 mg/L (analytically confirmed nominal concentration)

Algae: 72h-ErC50 > 100 mg/L (analytically confirmed nominal concentration); 72h-ErC10 = 83.54 mg/L (95% CL: 67.25 -103.77 mg/L; analytically confirmed nominal concentration)

In addition, no activated sludge respiration inhibition test is available on the registered substance. However, the toxicity effect of the test substance to microorganisms has been determined in the toxicity control of the biodegradation study (Givaudan, 2005), performed on the registered substance according to OECD Guideline 301F, EU Method C.4 -D with GLP compliance. The results obtained with the reference substance alone (benzoic acid, sodium salt) and with the test substance + reference substance shows no toxic effect of the test substance to the micro-organisms at the test concentration (100 mg/L). Therefore, the test substance should be regarded as not toxic to microorganisms up to 100 mg/L.
