Additional information
Toxicity to microorganisms was assessed based on data on target substance, using data on Similar Substance 01 as supporting evidence. Details on the read across are reported in section 13.
An available study on target substance according to OECD guideline 209 was used as key study. Toxicity to microorganisms in terms of inhibition of respiration rate was recorded after 3 h of exposure.
Only a summary of results on Similar Substance 01 was available with no details on test procedure or duration of exposure. Such data was taken as a confirmatory evidence of toxicity to microorganisms.
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.
