Description of key information
Additional information
For the aquatic toxicity of 2-{3-[(4-amino-2-methylpyrimidin-5-yl)methyl]-4-methyl-1,3-thiazol-3-ium-5-yl}ethyl hydrogen phosphate (CAS 10023-48-0) guideline studies performed under GLP standards are available for the short-term toxicity to all three trophic levels (fish, aquatic invertebrates and algae), for the long-term toxicity to one trophic level (aquatic algae) as well as for microorganisms of activated sludge.
The short-term toxicity tests for fish (OECD 203), aquatic invertebrates (OECD 202) and algae (OECD 201) showed no effects up to a nominal concentration of 100 mg/L. The long-term toxicity test with aquatic algae showed no long-term effects up to the nominal concentration of 100 mg/L. The respiration inhibition study (OECD 209) resulted in a NOAEC (3 h) of ≥ 1000 mg/L, indicating the substance is not toxic to activated sludge 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.
