Additional information

The study conducted by SRTC (1996) was GLP compliant and followed standard guidelines. This study reported 96 hour LC50 for Oncorhynchus mykiss was 0.58 mg/L. Suitable precautions were implemented to take into account the volatility of 2,4,4 -trimethylpentene.

The short-term aquatic toxicity to this substance was estimated using the Target Lipid Model based on methologies described by Mcgrath et al. (2004). The estimated LL50 for this substance is 0.778 mg/L.
