Description of key information

The EC50 value is above solubility of the substance. Therefore we conclude, that Anthraquinone is not dangerous for aquatic organisms.

Key value for chemical safety assessment

Additional information

The highest observed reduction in reproductive output of Daphnia was 1.8 % in the preliminary test. Therefore exact values of EC50 could not be calculated and the values of EC50 are given in the form of a range. The average measured concentrations of the test substance were used for all evaluations and results.
