Description of key information
Long-term toxicity to fish is not expected
Key value for chemical safety assessment
Additional information
Studies on the chronic toxicity of the substance to fish are not available. The substance is insoluble in water and the available short-term toxicity studies for fish, daphnia and algae indicate no aquatic toxicity of the substance to aquatic organisms. The available chronic data for aquatic invertebrates (OECD 211) and algae (OECD 201) determined no chronic effects of the substance. Since there is no indication in the short-term tests that invertebrates are less sensitive than fish, it is unlikely that a long-term test with fish will generate different results than the available long-term study with aquatic invertebrates. The available study on the bioaccumulation potential of the substance in fish determined BCF values clearly < 2000 L/kg. Based on these considerations and in order to avoid unnecessary vertebrate testing for animal welfare reasons, no further long-term test with fish was proposed.
In summary, the chemical safety assessment carried out according to Annex I of Regulation (EC) No 1907/2006 does not indicate the need to investigate further the long-term toxicity to fish. Thus, in accordance to Annex IX, column 2 no further long-term toxicity test to fish is proposed.
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.
