Results and discussion
Effect concentrations
- Duration:
- 96 h
- Dose descriptor:
- NOEC
- Effect conc.:
- > 156 mg/L
- Nominal / measured:
- meas. (arithm. mean)
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Details on results:
- The 96-hour NOEC (highest concentration tested without toxic effects after the exposure period of 96 hours), and the 96-hour LC0 of YELLOW MGi 1301 ro Rainbow trout were determined to be at least 156 mg test substance/I. The NOEC and the LC 0 might even be higher than this concentration, but concentrations in excess of 156 mg test substance/l have not been tested. The 96-hour LOEC (lowest concentration with toxic effects), the 96-hour LC50 and the 96-hour LC100 were clearly higher than 156 mg test substance/I. These values could not be quantified due to the absence of toxicity of YELLOW MGi 1301 up to the tested concentration.
Applicant's summary and conclusion
- Conclusions:
- NOEC (96 h) = 156 mg/l, measured concentration
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
