Additional information
In accordance with the GHS criteria for classification of substances for acute aquatic toxicity, Acute aquatic toxicity values should be as follows: 96-hr LC50 (for fish) ≤ 1 mg/l and/or 48 hr EC50 (for crustacea) ≤ 1 mg/l and/or 72 or 96 hr ErC50 (for algae or other aquatic plants) ≤ 1 mg/l.
Classification for chronic aquatic toxicity will be relevant for not rapidly degradable substances with BCF ≥ 500 (or log Kow ≥ 4), or for substances with BCF ≥ 500 (or log Kow ≥ 4), and with chronic toxicity values (NOEC) ≤ 1 mg/l.
Based on the acute aquatic toxicity data summarised here, butylbenzene is not classified for acute aquatic toxicity.
Based on the chronic aquatic toxicity data summarised here, butylbenzene is classified for chronic aquatic toxicity as follows: Aquatic Chronic 2; H411: Toxic to aquatic life with long lasting effects.
Conclusion on classification
For effects on environment, butylbenzenes are classified as Aquatic Chronic 2; H411: Toxic to aquatic life with long lasting effects.
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.
