Description of key information

Anthraquinone-2-sulfonic acid sodium salt exhibits a water solubility of 5.29 g/L. The following results provide information on ecotoxicological behavior in the aquatic compartment.

6.1.3 Acute toxicity to daphnia: No toxic effects against daphnia were observed at a limit test concentration of 100 mg/L (48hr-EC50 > 100 mg/L) under exposure conditions. The results are expressed in terms of nominal concentrations.

6.1.5 Toxicity to aquatic algae: A 72hr-ErC50 value of > 100 mg/L and a NOEC (growth rate) of 6.3 mg/L against algae at the

limit of water solubility under exposure conditions were determined. The results are expressed in terms of nominal concentrations.

All studies were conducted according to national and/or international guidelines. The toxicity studies are classified as acceptable and satisfy the guideline requirements.
