Description of key information

Short-term toxicity to invertebrates

No toxic effects of the test item were recorded up to the solubility limit of the test item in the test medium, which corresponds to 0.188 mg/L (geometric mean measured) and a nominal loading rate of 100 mg/L. Therefore, the 48-hour EC50 was determined to be > 0.188 mg/L (geometric mean measured).

Toxicity to aquatic plants other than algae:

In a 7-day growth inhibition study on Lemna sp. (Lemna gibba) the obtained results showed that the test item Leuco Sulphur Brown 46 had no toxic effects on the test system up to the solubility limit of the test item in the test medium. The 7-day NOEC was determined to be 0.121 mg/L (nominal 5 mg/L). The 7-day LOEC was determined to be > 0.121 mg/L (nominal > 5 mg/L). All validity criteria were met. The results are based on geometrical mean measured test item concentration. Test solution was prepared by utilizing the water accommodated fraction (WAF) approach.
