Description of key information

Key value for chemical safety assessment

Additional information

The terrestrial chemical safety assessment has been conducted using the Equilibrium Partitioning method (EQPM). It is recognised that the aquatic PNEC used in the EQPM does not take into account any indicator for effects in aquatic microorganisms. However, the OECD 209 activated sludge respiration inhibition test recorded a 3 hour EC10 of =100 mg/l (nominal) and no inhibition was observed in the test (Desmares-Koopmans 2009, see Section 6.1.7). Therefore it is unlikely that the PNECterrestrial based on aquatic ecotoxicity test results would not be protective for terrestrial microorganisms. The chemical safety assessment using EQPM does not suggest any unacceptable risks for the terrestrial compartment.
