Description of key information
Expected to be toxic for aquatic life
Additional information
No experimental data is available on target substance.
An experimental data is available on a structural analogue, i.e. 1,4-dihydroxyanthraquinone (CAS 81-64-1, EC 201-368-7); based on the structural similarity, it is considered as representative of the target substance. In particular, toxicity to alagae in a 72 -hour test shows EC50 = 0.044 mg/l.
Short-term and chronic toxicity of target substance to aquatic species, i.e. fish, daphnid and green algae, was additionally evaluated by means of ECOSAR v2.0 tool. The target substance was attributed to two ECOSAR classes, based on the molecular structure: phenol, poly class. In all cases, the ECOSAR analysis indicates the target substance to have a high potential for aquatic toxicity (EC50 below 1). This result is in line with the outcomes obtained for the similar substance.
Based on available information, the target substance is classified for aquatic toxicity Acute 1 and Chronic 1 according to the the CLP Regulation (EC 1272/2008).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
