Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The 96 hour LC50 of methyl ethyl sulphide to Danio rerio is greater than 49.8 mg/L as there was no mortality or visible abnormalities at the highest concentration tested (100 mg/L nominal, equal to 49.8 mg/L average exposure after 96 hours).
Key value for chemical safety assessment

Additional information
The toxicity of diethyl sulphide to fish has been read across from methyl ethyl sulphide. These substances are sulphides characterised by a sulphur atom in a carbon chain with the same structure over very similar carbon chain lengths (C4 for diethyl sulphide and C3 for methyl ethyl sulphide). Similarities between the available data for acute toxicity to Daphnia and algae show the similarity of the ecotoxicological properties of the two substances.
Gancet (2006) is a GLP-compliant, semi-static study which follows OECD guidelines 202. The study fulfils the validity criteria and is considered reliable and suitable for use for this endpoint. No mortality or visible abnormality was observed at the highest concentration tested and so the LC50 was determined to be above the highest concentration tested.
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.
