Description of key information
Additional information
Data on the aquatic toxicity of tefuryltrione is available for three different trophic levels (fish, aquatic invertebrates, algae). The most sensitive organisms in the available studies were green algae. In a study on Pseudokirchneriella subcapitata an ErC50 (72 h) of 5.3 mg/L (meas. arith. mean) was determined (NOErC: 1.6 mg/L meas. arith. mean). No acute effects were observed in the short-term toxicity studies with fish and aquatic invertebrates. The determined E(L)C50 values were > 100 mg/L based on the nominal test substance concentrations.
The available study on the toxicity to microorganisms determined no inhibition of the microbial respiration rate (EC10 (3h) > 1000 mg/L).
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.
