Results and discussion
Effect concentrations
- Duration:
- 96 h
- Dose descriptor:
- EC50
- Effect conc.:
- 548.6 mg/L
- Nominal / measured:
- meas. (not specified)
- Conc. based on:
- test mat.
- Basis for effect:
- not specified
- Remarks on result:
- other: The conduction ofan algae test with C.I. Pigment Violet 19 is problematic as the substance leads to a strong coloring of test solution and therefore to a reduction of light intensity.Therefore,assessment is made on the basis ofcomputer model estimation.
