Description of key information
There are two studies available for two separate genus of freshwater fish. Difficulties were encountered in solubilising the test substance. The LC50 values of >18.5 mg/L and >18.7 mg/L are based on the results of the limit tests. In both cases a NOEC is based at the highest concentration of the limit tests of 18.5 mg/L and 18.7 mg/L.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 18.5 mg/L
Additional information
In two separate studies the acute toxicity of the test substance to the rainbow trout (Salmo gairdneri) and fathead minnow (Pimephales promelas) was determined. Spec ifically regarding 96-hour, static, aquatic effects on the two genus of fresh water fish. Both studies experienced difficulty solubilising the test substance and completed a limit test, to a higher dose level that more closely approximated the aqueous solubility of the test substance. Tests were completed in duplicate and the limit test LC50 (96h) was >18.5mg/L and NOEC (96h) >18.5 mg/Lin both studies.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
