Additional information

One study, valid without restrictions, is available according to OECD guideline 202. The test substance is not toxic to Daphnia magna as can be seen from the preliminary test with adjusted pH. No animals were immobilized upto 334 mg/L. Therefore the 48h-EC50 for p-TSC is greater than 334 mg/L.
