Description of key information

The 96h-LC50 obtained after exposure of Danio rerio to the test substance according to OECD 203 testing guideline is 1.65 mg/L.

Key value for chemical safety assessment

LC50 for freshwater fish:
1.65 mg/L

Additional information

Zebrafish (Danio rerio) were exposed for 96 hours under flow-through conditions to five mean measured concentrations of tricyclodecane dimethanol, esters with acrylic acid ranging from 0.42 to 2.12 mg/L according to OECD 203 testing guideline. Based on the mean measured concentrations, the 96‑hour LC50 value was 1.65 mg/L, with a 95% confidence interval of 1.51 to 1.79 mg/L. The slope of the concentration-response curve was 12.6. The NOEC was 0.63 mg/L based solely on the mortality data.
