Description of key information
OECD 209 Activated sludge respiration inhibition 3 hour EC50 402 mg/L, EC10 134 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 402 mg/L
- EC10 or NOEC for microorganisms:
- 134 mg/L
Additional information
The toxicity of the test itemMonoFA_DimerFA_TETA_TEPA_PAA (batch no.: BB 001148 V1) to activated sludge was determined in accordance with OECD Test Guideline 209 at Akzo Nobel, Arnhem, The Netherlands.
The toxicity of MonoFA_DimerFA_TETA_TEPA_PAAto activated sludge was determined at a contact time of 3 hours, using various concentrations of the test substance.
The EC50of MonoFA_DimerFA_TETA_TEPA_PAAfor activated sludge after 3 hours contact time is 402 mg/L. The EC10and EC20 are 134 and 195 mg/L, respectively.
MonoFA_DimerFA_TETA_TEPA_PAAis therefore considered not harmful to activated sludge.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
