Additional information
The toxicity of the test item (Pigment Yellow 74) to the unicellular freshwater green alga Desmodesmus subspicatus was determined according to the principles of OECD-Guideline 201. A limit test with a saturated solution was carried out.
No inhibiting effects on specific growth rate and yield were found in the saturated solution of 2 mg/L. The EC50-values for specific growth rate inhibition (ErC50) and inhibition of yield (EyC50) after 72 h were higher than the saturation level of the test item.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).
