Description of key information
Additional information
Two key studies were performed to assess toxicity of FAT 40865/A TE following GLP and OECD test guideline 221 and 202 on freshwater plant Lemna gibba and freshwater invertebrate Daphnia magna respectively.
The EC50 of FAT 40865/A TE in Daphnia magna observed for a period of 48 hours was calculated as 34.58 mg/L with upper confidence limits of 60.32 mg/L and lower confidence limits of 21.20 mg/L and regression equation Y = 1.3269 + 2.387 log (x).
Lemna gibba (Duckweed) were exposed to the test item (FAT 40865/A TE) at different test concentrations viz.,0.3, 0.96, 3.07, 9.83, 31.46 and 100.66 mg/L . At the end of 7 days the following endpoints were recorded:
ErC50 of FAT 40865/A TE based upon the frond numbers observed for a period of ‘7’ days for Lemna gibba was calculated as 25.03 mg/L with upper confidence limits of 26.80 mg/L and lower confidence limits of 23.37 mg/L.
EyC50 of FAT 40865/A TE based upon the frond numbers observed for a period of ‘7’ days for Lemna gibba was calculated as 7.65 mg/L with upper confidence limits of 8.13 mg/L and lower confidence limits of 7.19 mg/L.
ErC50 of FAT 40865/A TE based upon the frond dry weight observed for a period of ‘7’ days for Lemna gibba was calculated as 19.43 mg/L with upper confidence limits of 21.04 mg/L and lower confidence limits of 17.94 mg/L.
EyC50 of FAT 40865/A TE based upon the frond dry weight observed for a period of ‘7’ days for Lemna gibba was calculated as 5.02 mg/L with upper confidence limits of 5.33 mg/L and lower confidence limits of 4.72 mg/L.
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.
