Description of key information
Additional information
For all trophic levels short-term studies are available. At neutral pH p-TSC is not toxic to aquatic organisms:
Short-term toxicity to fish: The 96h-LC50 for p-TSC is greater than 100 mg/L.
Short-term toxicity to invertebrates: The 48h-EC50 for p-TSC is greater than 334 mg/L.
Short-term toxicity to algae: The 72h-ErC50 is greater than 100 mg/L.
For algae a long-term endpoint is available as well. The NOErC is 2.6 mg/L at neutral pH.
For toxicity to microorganisms one study is available. The 3h-EC10 for respiration rate was ca. 156 mg/L, based on nominal active ingredient p-TS Acid, which is equivalent to 173 mg/L p-TSC.
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.
