Additional information

Acute immobilisation in Daphnia has been investigated in a 48 hour test according to OECD test methods with a structurally similar trimellitate, tri(2 -ethylhexyl)trimellitate (TOTM).

Dissolution/dispersion agents were used to increase concentration of the substance in the test medium. The EC50 (48h) was determined to be >180 mg/L and the NOEC was 180 mg/L, the highest concentration investigated.

Adjusting for differences in molecular weight between the tested substance and the registered substance, these values equate to an EC50 (48h) of >194 mg/L and a NOEC of 194 mg/L.
