Nominal / measured:

Conc. based on:
test mat.
Basis for effect:
other: mortality and sublethal effects
Remarks on result:
other: Due to the very poor solubility of the test item, quantitative analytical determination was precluded (below LOQ)
Duration:
96 h
Dose descriptor:
LC50
Effect conc.:

Nominal / measured:

Conc. based on:

Basis for effect:
mortality
Remarks on result:
other: Due to the very poor solubility of the test item, quantitative analytical determination was precluded (below LOQ)
Reported statistics and error estimates:
The concentration leading to 0 and 100 % mortality (LC0 and LC100) after 96 h were determined directly from the test results. LC50-values have not to be calculated in a limit test.
