Conclusion on classification
In the absence of adequate aquatic chronic toxicity information from all three trophic levels, the classification was based on the results from short-term aquatic toxicity testing (algal growth inhibition test, acute daphnid immobilsation test and acute fish toxicity test). The lowest L(E)C50 from among the three trophic levels was the 48-h EC50 in daphnids, reported as 0.56 mg/L < EC50 < 1.0 mg/L for the short-term toxicity of dec-1-ene through read-across. Although the substance was not shown to be readily biodegradable, the substance exhibited inherent primary degradability and substantial mineralisation (i.e., 41-42 % in 28 days under the strictly controlled conditions of a ready biodegradability assay on alkenes C6-8, through read-across). Therefore, while the substance is not expected to be very persistent in the environment, it does exhibit the potential to be persistent. The reported experimentally-determined value for theoctanol-water partition coefficient (log Kow) for octene of 4.51 is above the criterion (log Kow≥ 4.0) for possible environmental classification. Therefore, food chain exposures and bioaccumulation of the substance are of potential concern. Thus, the substance was assigned a Category Acute 1 classification with an M-factor of 1 and a Category Chronic 1 classification with an M-factor of 1. Based upon its environmnetal classification, the substance is assigned Pictogram Code GHS09 (environment symbol), Signal Word Code Wng (“Warning”), Hazard Statement H400 (“Very toxic to aquatic life”) and H410 (“Very toxic to aquatic life with long-lasting effects”), and Precautionary Statements P273 (“Avoid release to the environment”), P391 (“Collect spillage”) and P501 (“Dispose of contents/container to…”).
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).
