We have used the SRTC (1996) study as the key study for short tem
toxicity to fish, aquatic invertebrates and algae. It is also the key
study for these endpoints in the EU RAR (2008) for 2,4,4
-trimethylpentene. Since the EU RAR was produced, a long term toxicity
to aquatic invertebrates study has been conducted and this has been
selected as key. All studies selected as key are GLP compliant and
follow standard guidelines.
The most conservative value reported is a 96 hour LC50 of 0.58 mg/L for
acute toxicity to fish and a 0.16 mg/L 21 day NOEC for chronic toxicity
to aquatic invertebrates. This would result in a category 1 chronic
hazard to the environment and the hazard statement 'very toxic to
aquatic life with long lasting effects' in the classification and
