Additional information
The acute toxicity of ethyl methyl sulfide was evaluated with Danio rerio in a study performed in accordance with OECD testing guideline 203 and GLP. The fish were exposed to a concentration of 100 mg/L under semi-static conditions with a renewal of test solutions every 24h. No mortality was observed at this concentration. Validity criteria were fulfilled but the concentration of the substance was not maintained during the test. Therefore, average measured concentrations were used to express lethal concentrations. LC50_96h > 49.8 was obtained.
The acute toxicity of ethyl methyl sulphide was determined in Daphnia magna in accordance with OECD testing guideline 202 and GLP requirements (Thiébaud, 2000). 20 test organisms per concentration were exposed under static conditions to doses of 0, 1, 2.1, 4.7, 10.3, 22.7 and 50 mg/L (nominal concentrations). The final concentrations of methyl ethyl sulfide were maintained within the designated limit of 80% of the initial concentrations. Therefore, the effect concentrations and NOEC have been calculated using the initial measured concentrations. The validity criteria of the study were fulfilled. The calculated EC50_48h was 16 mg/L.
The determination of the growth inhibition of the fresh algaePseudokirchneriella subcapitataexposed to ethyl methyl sulphide for a duration of 72h was performed following the method OECD 201 and according to GLP (Thiébaud, 2001). Algae were exposed to the following nominal concentrations for 72h: 0, 76, 122, 195, 313 and 500 mg/L. The final concentrations of methyl ethyl sulfide were maintained within the designated limit of 80% of the initial concentrations in non inoculated flasks. Therefore, the effect concentrations and NOEC have been calculated using the nominal concentrations. The results show that ErC50 and NOECr (based on growth rate) are higher than 500 mg/L and 76 mg/L, respectively.
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.
