Description of key information

Due to dark color of the substance, the study to determine the acute toxicity to aquatic algae and cyanobacteria cannot be performed.

Key value for chemical safety assessment

Additional information

Due to intrinsic properties of the substance (dark colored dye), the study to determine the acute toxicity to aquatic algae and cyanobacteria cannot be performed. The dark coloration of the test medium and reduced light intensity in the medium modifying the conditions of test. Hence, in order to fulfil this endpoint requirement, a toxicity study to the aquatic plant Lemna minor (a semi-static growth inhibition test) was performed.
