Description of key information
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.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 173 mg/L
Additional information
One study, valid with restrictions, is available with p-TS Acid, as p-TSC is instantly hydrolysed to p-TS Acid, this study can be used here. Activated sludge of a predominantly domestic sewage was exposed for 3 hours to p-TS Acid, according to OECD guideline 209. 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).
