Additional information
The toxicity of the test item OLEIC_DimerFA_TETA_PAA (batch no.: BB 100860 V1) to activated sludge was determined in accordance with OECD Test Guideline 209 at Akzo Nobel, Arnhem, The Netherlands.
The toxicity of OLEIC_DimerFA_TETA_PAA to activated sludge was determined at a contact time of 3 hours, using various concentrations of the test substance.
The EC50of OLEIC_DimerFA_TETA_PAA for activated sludge after 3 hours contact time is 421 mg/L. The EC10,EC20 and EC80valuesare 233, 285 and 621 mg/L, respectively.
OLEIC_DimerFA_TETA_PAA is therefore considered not harmful to activated sludge.
