The LC50 after 96 hours was 14.1 (10.0 - 20.0) mg/L (nominal test item concentration).
The acute toxicity of the test item to zebrafish was determined
according to the principles of the OECD-Guideline No. 203 and EU Method
C.1. It is therefore, given the reliability rating of 1 (reliable
An acute toxicity test under semi-static conditions with renewal of the
test media after 48 hours was conducted with the nominal test item
concentrations of 1.25, 2.50, 5.00, 10.0 and 20.0 mg/L (factor 2).
Duration of the test was 96 hours. Seven test organisms were exposed to
each test concentration and the control. Water quality parameters (i.e.
temperature, pH-value and oxygen- saturation) measured at 0, 24, 48, 72
and 96 hours were determined to be within the acceptable limits.
All validity criteria of the test guideline were met.
The test item was found to cause lethal effects to zebrafish after 96
hours at a nominal test item concentration of 20.0 mg/L. The LC0 and
LC100 after 96 hours was 10.0 mg/L and 20.0 mg/L (nominal test item
concentration). The LC50 after 96 hours was 14.1 (10.0 - 20.0) mg/L
(nominal test item concentration).
