Description of key information
Short-term toxicity to fish
The acute toxicity of cyclohex-3 -ene-1 -carbaldehyde to fish was investigated in two acute toxicity studies (Bayer 1983, Deneer 1988).
The available studies for cyclohex-3-ene-1-carbaldehyde provide an approximation of the aquatic toxicty of the substance. The LC50 to the investigated fish lies between 1.1 mg/L (Deneer 1988) and 34 mg/L (Bayer 1983) and the lower value is chosen as key value as a worst case. However, the substance is registered in the tonnageband art. 18 1 - 1000 t/a and therefore no further assessment is stipulated.
Short-term toxicity to aquatic invertebrates
The acute toxicity of cyclohex-3-ene-1-carbaldehyde to aquatic invertebrates (Daphnia magna) was tested equivalent or similar to EU method C.2 'acute toxicity for Daphnia'. During 48 hours exposure, an EC50 of 40 mg/L was obtained.
Toxicity to microorganisms
The respiration inhibition on activated sludge whitin 3 hours was measured at EC 50 of 473 mg/L.
Additional information
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.
