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.
