Key value for chemical safety assessment
Additional information
A key study was performed to determine the toxicity of Acid Violet 054 in activated sludge for 3-hours respiration inhibition test according to OECD Guideline No. 209 (Huntsman, 1994)
The test was performed in compliance with the Good Laboratory Practice (GLP) Regulations of Switzerland.
The test substance concentrations tested were 320,100, 32 and 10 mg/l.
The reference substance, 3, 5-Dichlorophenol was tested in concentrations of 32, 10 and 3.2 mg/l.
Results:
IC50 (3 h) = 100.0 mg/l
IC20 (3 h) = 18.5 mg/l
IC50 (3 h) of the reference substance 3,5-Dichlorophenol: 12.0 mg/l
In several supporting studies (Huntsman, 1982, FAT - 21'020/B; Huntsman, 1976, FAT - 21'020/A ) the BST values were determined as >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.
