Additional information
The lowest acute effect concentration for the test substance is the 96-hour EC50 of 154.9 for algae. Since a full base set of acute aquatic test data is available, an assessment factor of 1000 is appropriate for calculation of a PNEC aqua-freshwater. The Predicted No Effect Concentration for surface water is PNECwater= 0.155 mg/L.
The PNEC aqua-marine water was derived from the freshwater base set of test using an AF of 10,000. The Predicted No Effect Concentration for marine water is PNECaqua - marine water= 0.016 mg/L.
The PNECs for freshwater sediment, marine sediment, and soil were derived from the appropriate PNEC values, the Koc value for the dominant non-aqueous-phase constituent in the test substance (Koc = 7.8 mL/g) and appropriate equilibrium partitioning equations.
The PNECSTPwas derived from the Pseudomonas study endpoint of > 1600 mg/L in conjunction with an AF of 10.
Based on a log Kow < 3.0, limited potential for exposure and bioaccumulation and lack of classification for toxicological effects in mammals, it was not considered useful to derive a PNECoral.
Conclusion on classification
Conclusive but insufficient for classification
