Exposure of rainbow trout (Oncorhynchus mykiss) to the read-across
substance TMR2 (Hydroxypropyl, 2-, trimethylammonium formate) in and an
OECD 203 test gave LC50 values based on the nominal concentration of
greater than 100 mg/L. The No Observed Effect Concentration was 100 mg/L.
An OECD 203 semi-static test in Oryzias latipes using the dissociation
product 2-ethylhexanoic acid derived a 96hour LC50 of >100 mg/L.
On this basis an LC50 of 100 mg/L. is assigned to TMR
