Additional information
The toxicity of the test item DimerFA_PEPA_PAA (batch no.: BB 001694 V1) to activated sludge was determined in accordance with OECD Test Guideline 209 at Akzo Nobel, Arnhem, The Netherlands.
The toxicity of DimerFA_PEPA_PAAto activated sludge was determined at a contact time of 3 hours, using various concentrations of the test substance.
The EC50of DimerFA_PEPA_PAAfor activated sludge after 3 hours contact time is 314 mg/L. The EC10 and EC20valuesare 71 and 118 mg/L, respectively.
DimerFA_PEPA_PAAis therefore considered not harmful to activated sludge.
