Description of key information

For the substance, information on acute aquatic toxicity data on all three trophic levels are available. This includes for acute toxicity on zebrafish Danio rerio, on immobilization of the waterflea Daphnia magna and of toxicity on green algae. Furthermore for one ‘red disazo condensation pigment’ long-term data on reproduction of the waterflea Daphnia magna are available, which was used as read-across information.

No effects on aquatic organisms occurred within the range of water solubility, neither in acute nor in chronic studies. These results confirm the expectation that the substance is considered to be essentially not bioavailable, due to the large molecular size together with the negligible low solubility.
