Description of key information

Not toxic to aquatic plants.

Key value for chemical safety assessment

EC50 for freshwater plants:
320 mg/L

Additional information

A GLP guideline study according to OECD 221 using Lemna gibba as a test organism was conducted on similar substances.

All the available tests were conducted instead of a study using algae because the test substance is a dyestuff which would influence the photosynthesis capacity of algae cells in the test solution.

In the key study, the ErC50 (7d) values on the frond number and the dry weight of the plants were determined to exceed the analytically verified test concentration of 2590 mg/L. The absence of adverse effects is confirmed by the supporting study with a EC value > 320 mg/l.
