Description of key information
The TLM-EqP modeling has been validated as a suitable method for predicting effect values in sediment and soil organisms. The TLM-EqP predicted effect values for 2,4,4 -trimethylpentene were 184.459 and 35.337 mg/kg soil dw for short-term (28-day LL50) and long-term effects (56-day NOELR), respectively.
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil macroorganisms:
- 184.459 mg/kg soil dw
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 35.337 mg/kg soil dw
Additional information
This substance is considered to have a Soil Hazard Category 4 classification because no biodegradation was observed during the test and the has an EC50< 1 mg/L. Therefore, we are required to conduct a conduct long-term toxicity tests according to the standard information requirements Annex X (invertebrates and plants), and choose the lowest value for derivation of PNECsoil according to ECHA (2017) Guidance on information requirements and chemical safety assessment, chapter R7c: endpoint specific guidance.
