Description of key information
Short-term aquatic invertebrates: OECD 202; Daphnia magna 48h EC50 was 66.2 mg a.i./L.
Freshwater Algae: OECD 201; Raphidocelis subcapitata 72h EC50 and EC10 values for growth rate were determined to be 53 and 18 mg/L, respectively. The 72h NOEC was 11 mg/L.
Additional information
Two aquatic toxicity studies are available for substance BTFB: a 72-h growth inhibition study with freshwater alga Raphidocelis subcapitata and a 48-h immobility study with Daphnia magna. Due to the test substance volatility in both tests, rigorous precautions were taken to minimize losses through evaporation. Both studies were conducted under closed-system conditions with minimized headspace. Additionally, special precautions were taken during collection and analysis of samples to avoid losses through volatilization. Despite the special handling and precautions, the measured concentrations resulted in concentrations well below the nominal concentrations. The severe effect of volatilization was especially noted during the analytical treatment of D. magna samples where the analytical concentrations were only 3.2 to 13% of the nominal concentrations, therefore nominal concentrations are more representative of exposure to the test system. Based on the rapid volatilization of BTFB from aqueous media, BTFB is not expected to produce adverse effects in aquatic species.
Based on its aquatic toxicity and lack of biodegradability, BTFB is classified as Aquatic Chronic 3.
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.
