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 28-day effect values for 2,4,4 -trimethylpentene were 103.729 and 19.871 mg/kg soil dw for short-term (LL50) and long-term effects (NOELR), respectively.
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil dwelling arthropods:
- 103.729 mg/kg soil dw
- Long-term EC10, LC10 or NOEC for soil dwelling arthropods:
- 19.871 mg/kg soil dw
Additional information
This substance is considered to have a Soil Hazard Category 4 classification as it is considered persistent and has a log Kow of 5. Using the EPM method for deriving soil PNECs and following an exposure assessment the resulting RCRs are all <1 (see CSR in Section 13). However, A long-term terrestrial test is required to confirm that further terrestrial studies are not required.
