Description of key information
The toxicity of Pigment Red 112 to the unicellular freshwater green algae Desmodesmus subspicatus was determined according to the principles of OECD 201. In this study the test item was found not to inhibit the freshwater green algae Desmodesmus subspicatus after 72 h at the saturated solution (prepared with 1 mg/L). All effect levels are given based on the nominal concentration of Pigment Red 112.
The toxicity of Pigment Red 210 to the unicellular freshwater green alga Desmodesmus subspicatus was determined according to the principles of OECD 201 and compliant to GLP (reliability category 1). The aim of the study was to assess the effects on growth rate and yield over a period of 72 hours. Due to the test item being highly insoluble in water a saturated solution* with a nominal concentration of 1 mg/L was tested and no analytical determination was carried out since no suitable method for the determination of the test item could be established. In this study no inhibition on growth of the freshwater green alga Desmodesmus subspicatus was found after 72 hours exposure to the test item. The NOEC for inhibition of specific growth rate and yield after 72 hours was 1.00 mg/L.

Additional information
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.
