Description of key information
Determination of the acute toxicity of FAT 41024/B for Zebra-fish.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 1.5 mg/L
Additional information
FAT 41024/B was tested for its acute toxicity to Zebra-fish in a 96 hours static test.
Results:
Due to the very low water solubility of the test substance in water the actual concentrations of dissolved test substance in the analysed
test media were below the analytical detection limit of 1.5 mg/l. The test solution was prepared according to the "OECD_Guidance
document on aquatic toxicity testing of difficult substances" (Draft June 1998] and the "Guidance on the aquatic toxicity testing of
difficult substances" (Department of the Environment, London, United Kingdom, May 1996) to ensure that the fish were exposed to
the maximum achievable dissolved concentration of the test substance in the test medium (= saturation concentration).
LC-values after 24, 48, 72 and 96 hours:
- LC50 > saturation concentration (> 100 mg/l nominal, < 1.5 mg/l actual concentration) (95% confidence limit n.d.)
- LC0 saturation concentration (100 mg/l nominal, < 1.5 mg/l actual concentration)
- LC100 > saturation concentration (> 100 mg/l nominal, < 1.5 mg/l actual concentration)
n.d. for the present data, this value could not be determined
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
