- Details on results:
- MORTALITY
No mortality was observed in the control and 100 mg/L test concentration. At the test concentration of 215 mg/L 2 fish (20%) were dead after 24 hours exposure and 3 fish (30%) were dead after 96 hours. At the test concentration of 464 mg/L all 10 fish were dead after 4 hours. At the highest tested concentration all fish had died within 1 hour exposure. See 'Any other information on results incl. tables'.
SYMPTOMS:
No symptoms of toxicity were observed in any of the test concentrations. - Results with reference substance (positive control):
- - LC50 after 48h: about 31 mg/L (determined 30 Nov 1987), this lethal concentration corresponds to the normal sensitivity
- Results with reference substance were valid - Reported statistics and error estimates:
- Determination or calculation of the median lethal concentration (LC 50) and, if possible the LC 5 and the LC 95 using the probit analysis.
- Sublethal observations / clinical signs:

Reference
Description of key information
The 96-h LC50 value for Basacryl-brilliantrot x 4G is ca. 250 mg/L in freshwater fish (Leuciscus Idus L.).
Key value for chemical safety assessment
Additional information
The short-term toxicity of Basacryl-brilliantrot x 4G to freshwater fish was determined in a study according to DIN 38 412. In this study, groups of 10 Golden Orfe (L. idus) were exposed to nominal test substance concentrations of 0 (control), 100, 215, 464 and 1000 mg/L for 96 hours under static conditions. Test concentrations were not analytically verified. Incidences of mortality and clinical effects were recorded after 1, 4, 24, 48, 72 and 96 hours exposure. No clinical effects were observed. No mortality was observed in the control and 100 mg/L test concentration. At the test concentration of 215 mg/L 2 fish (20%) were dead after 24 hours exposure and 3 fish (30%) were dead after 96 hours. At the test concentration of 464 mg/L all 10 fish (100%) were dead after 4 hours. At the highest tested concentration all fish had died within 1 hour exposure. Based on these findings the 96-h LC50 is determined at ca. 250 mg/L.
