Description of key information

In an experimental study, a 96hr LC50  for freshwater fish in the species Pimephales promelas of 2400mg/l was established. 
No symptoms of toxicity were observed at 1000 mg/l (NOEC).
The substance 2-(2-(2-butoxyethoxy)ethoxy)ethanol is an analogue of the test substance used in the study of Dawson GW, Jennings AL, Drozdowski D et al 1975. Correcting for molecular weight, a conservative LC50 of 2181.5 mg/l can be derived. (1250 x 206.28) / 118.2=2181.5mg/l for marine water fish (SW).

Key value for chemical safety assessment

LC50 for freshwater fish:
2 400 mg/L
LC50 for marine water fish:
2 181.5 mg/L
