Description of key information
The test item is not toxic to aquatic organism.
Additional information
FAT40810/A has been tested for acute toxicity towards fish, invertebrates (daphnia), aquatic plants (algae) and sewage sludge bacteria and was found not being toxic to any of these trophic levels.
The results in detail were as follows:
LC50 (zebra-fish, 96h): >100 mg/l
EC50 (daphnia, 48h): >100 mg/l
EC50 (scenedesmus subspicatus, 72h): >100 mg/l
IC50 (sewage sludge bacteria, 3h): >1000 mg/l
In addition a daphnia reproduction test has been performed which showed no effects on reproduction up to 50 mg/L. At 100 mg/L however, parental animals were immobilised which was observed as of day 5. Thus, the NOEC in this study was set to 50 mg/L for mortality and reproduction. FAT 40571/A has shown no signs of toxicity when tested in acute tests at three trophic levels (fish, algae and daphnia) at limit concentrations of 100 mg/l. Furthermore, it is known that FAT 40810 hydrolyses considerably under environmental conditions (pH 7 and 9) in the aquatic environment with a half-life of less than one day. Therefore, the substance can be regarded as rapidly degradable in the aquatic environment (according to CLP/GHS criteria) and is not expected to be present in the aquatic system for a longer time. Furthermore, an exposure assessment for the environment (surface water, sediment, soil) was carried out and shows that there is no risk for the aquatic environment (RCR <1). Thus, the chemical safety assessment does not indicate the need to investigate further the effects on aquatic organisms.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
