Endpoint summary
Administrative data
Description of key information
Reliable toxicity studies in invertebrates and algae (both rated as Klimisch 1) have been conducted for butyl ethyl ether and are included in the dossier.
The lowest EC50 was determined for Daphnia magna Straus in a 48-hour study according to the OECD test guideline 202 (2004) with 75.7 mg/L (Knauer 2017).
Additional information
Toxicity to invertebrates:
A short-term toxicity study with Daphnia magna Straus was performed with butyl ethyl ether in a GLP-compliant test according to the OECD guideline 202 (2004) with a 48-hour-EC50 (mobility) of 75.7 mg/L. Consequently, this value will be taken as the short-term toxicity in invertebrates endpoint for butyl ethyl ether.
Toxicity to algae:
A short-term toxicity study with freshwater algae (Raphidocelis subcapitata) was performed with butyl ethyl ether in a GLP-compliant test according to the OECD guideline 201 (2006) with a 72-hour-EC50 (growth rate) of 175.2 mg/L and a 72 -hour-NOEC (growth rate) of < 52.7.mg/L. The ErC50 value of 175.2 mg/L will be taken as the short-term toxicity in freshwater algae endpoint for butyl ethyl ether.
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.
