Conclusion on classification
The 96-hour LC50 for fish was > 120 mg/L, the 48-hour EC50 for crustacea was 1000 mg/L, and the 120-hour ErC50 for algae was 0.004 mg/L. The chronic NOEC for fish was 7.6 mg/L, for crustacea was 106 mg/L and for algae was 0.00052 mg/L. Additionally, the substance is considered not readily degradable. Based on all the available data, the test substance is classified as Acute Cat 1 (H400: Very toxic to aquatic life) and Chronic Cat 1 (H410: Very toxic to aquatic life with long lasting effects) according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
In accordance with article 10 of the CLP Regulation (EC) No 1272/2008, if an M-factor is not yet given in Part 3 of Annex VI to the CLP Regulation, an M-factor should be determined and a scientific justification provided, when classifying substances for Acute Category 1 or Chronic Category 1. For this substance, adequate acute aquatic data are available in fish, aquatic invertebrates, and algae. An Acute M-Factor is based on the lowest reported effects in the most sensitive species, algae. Therefore, the M factor is 100 based on the 120 h EC50 of 0.004 mg/L in algae.
In accordance with article 10 of the CLP Regulation (EC) No 1272/2008, if an M-factor is not yet given in Part 3 of Annex VI to the CLP Regulation, an M-factor should be determined and a scientific justification provided, when classifying substances for Acute Category 1 or Chronic Category 1. Chronic data were available in fish, invertebrates, and algae. The lowest reported effects in chronic data were the 120 h NOEC data of 0.00052 mg/L in algae. The test substance is Not biodegradable . Therefore, the M factor is 100.
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).
