Additional information

In a 21-day study conducted on daphnids the chronic toxicity of the read across- substance 9 -octadecenoic acid sodium salt (CAS number 143 -19 -1) to aquatic invertebrates was assessed. The test was performed following OECD guideline No. 211. As a result, an EC50 value of 0.33 mg/L and a NOEC of 0.11 mg/L were determined.
