LC50 for freshwater fish:
100 mg/L

Additional information

The acute toxicity to fish of the test substance was tested according to German Industrial Standards DIN 38 412, part 15 in a static freshwater test with Golden orfe (Leuciscus idus) as test organisms (BASF AG, 1989). Based on a range-finding test, the nominal test concentrations in the definitive test were: 4.64, 10.0, 21.5, 46.4 and 100.0 mg/L. Furthermore, a control and a reference substance (Chloroacetamide) were included. 10 organisms were introduced to each vessel, thus a biomass loading rate of 3.5 g/L was reported. A 16 h dark and 8 h light cycle was introduced. Physico-chemical parameters (i.e. temperature, dissolved oxygen and pH) were recorded after 1, 24, 48, 72, and 96 h. Tumbling was observed at the test concentration of 100 mg/L after 4 h of exposure. No mortality occurred, thus the LC50(96h) is reported as > 100 mg/L and Butylaminoethanol can be considered as non-toxic to freshwater fish.
