Description of key information

Respiration inhibition:NOEC - 1077 mg/L

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
1 077 mg/L

Additional information

A respiration inhibition test with activated sludge has been conducted on a structurally similar trimellitate, tri(2 -ethylhexyl)trimellitate (TOTM). A limit concentration of 1000 mg/L was investigated. No inhibition was observed and the NOEC was regarded as being 1000 mg/L. Adjusting for differences in molecular weight between the tested substance and the registered substance, this value equates to a NOEC of 1077 mg/L.

Potential nitrification inhibition by the registered substance itself has been determined using an activated sludge nitrification inhibition test. No inhibition of nitrification was observed in saturated solutions.
