Description of key information
ACID YELLOW 104 can be considered as not harmful to the aquatic ecosystem.
Additional information
Short term toxicity tests are available for all the three tropic levels (fish, invertebrates and aquatic plants).
The 48h TL50 of ACID YELLOW 104 to fish was determined to be greater than 1000 mg/L.
Exposure to freshwater invertebrate Daphnia magna to FAT 20041/D TE has been investigated and gave the following results:
48h EC50 = 60 mg/L (95 % Confidence Limits = 50-72 mg/L); NOEC (48h) = 18 mg/L; LOEC (48h) = 32 mg/L.
Further in a GLP-compliant OECD Guideline 221 study, Lemna gibba (Duckweed) were exposed to the test item FAT 20041 for 7 days. In this study, ErC50 and ErC50 based upon the frond number was greater than 100 mg/L, and ErC50 and EyC50 based upon the frond dry weight is also greater than 100 mg/L.
In an activated sludge respiration inhibition test, the IC50 value for ACID YELLOW 104 was determined to be greater than 300 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.
