Additional information
The toxicity of the test item TOFA_DimerFA_TETA_PAA (batch no.: BB 001030 V1) to activated sludge was determined in accordance with OECD Test Guideline 209 at Akzo Nobel, Arnhem, The Netherlands.
The toxicity of TOFA_DimerFA_TETA_PAA to activated sludge was determined at a contact time of 3 hours, using various concentrations of the test substance.
The EC50of TOFA_DimerFA_TETA_PAA for activated sludge after 3 hours contact time is 384 mg/L. The EC10, EC20and EC80are 130, 188 and 781 mg/L, respectively.
TOFA_DimerFA_TETA_PAA is therefore considered not harmful to activated sludge.
