Description of key information

Additional information

Short-term toxicity testing on invertebrates (preferred species Daphnia) and Activated sludge respiration inhibition testing are available for Direct Black 80, while short term toxicity to fish is available for the similar substance 3 and toxicity to Lemna minor is available for the similar substance 2.

At the experimental conditions all the studies do not show any toxicity due to the dye.

Based on the read across justification the same values for short term toxicity to fish and Lemna minor can be used for Direct Black 80.

The similarity between the substances, the molecular formula and the toxicological and eco-toxicological considerations are reported in the attached document in section 13.
