Additional information
Conclusion on classification
Acute toxicity:
Fish are the most sensitive species to the toxic effects of PSOA with an acute LC50 of 0.75 mg/L. Based on the results obtained in the aquatic toxicity studies, PSOA is classified as acute category 1 according to Regulation (EC) No 1272/2008 (CLP/GHS) and is assigned with hazard statement H400 'Very toxic to aquatic life'.
Chronic toxicity:
Fish are the most sensitive species to the toxic effects of PSOA with an acute LC50 of 0.75 mg/L. Classification is based on acute tests as no long term tests are available. As PSOA is not ready biodegradable and so the substance is classified as chronic category 1 with N; R50/53 (Dangerous for the environment; Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment) according to Directive 67/548/EEC (DSD) and chronic env. tox. cat. 1 (H410 Very toxic to aquatic life with long lasting effects) according to Regulation (EC) No 1272/2008 (CLP/GHS).
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.
