Additional information
The acute toxicity of ETU was evaluated with Poecilia reticulata in a study performed in accordance with OECD testing guideline 203 (GLP study : no data).
The fish were exposed to nominal test concentrations under semi-static conditions during 96 hours.
The LC50-96h was estimated using measured concentrations as being equal to 7500 mg/L.
Temperatures, pH range and dissolved oxygen concentration were not reported in this study, we consider the data were obtained based on the guideline requirements.
