Executive summary:

The short-term toxicity of Trans-hex-2-en-1-ol to aquatic invertebrates was determined during a GLP-compliant study performed according to the OECD Testing Guideline 202.

The species was Daphnia magna.

A range-finding test was performed to determine the concentrations to be used during the definitive test.

The 48-hour EC50 was 163 mg/L. The substance did not meet the criteria for classification as toxic to the aquatic environment according to Regulation (EC) N°1272/2008.
