Description of key information
Short-term toxicity to fish
No data on toxicity to fish was available for the registration substance itself. Therefore, a read across from the structural analogue Yellow 22 (CAS 90268-98-7) is conducted.
In the 96-hour test according to OECD Guideline 203 on Danio rerio Yellow 22 (CAS 90268 -98 -7) had no toxic effect on fish at aquatic saturation (i.e. limit test concentration). Accordingly, the 96 -h NOEC was determined to be 0.040 mg/L and the LOEC > 0.040 mg/L (based on total product), equivalent to 100 mg/L and > 100 mg/L nominal loading rate respectively.
Short-term toxicity to aquatic invertebrates
In the acute 48-hour Daphnia magna immobilisation study performed with the WAF (according to OECD Series on Testing and Assessment No. 23) including a nominal loading rate of 100 mg/L (total product), the obtained results showed that the test item had not any significant toxic effect on the test system. The 48 -h NOEC was determined to be 0.2 mg/L (limit of detection, nominal 100 mg/L). The 48 -h LOEC was determined to be >0.2 mg/L (limit of detection, nominal >100 mg/L).
Toxicity to aquatic plants other than algae
Since the test item is a dye which is expected to stain the water, the test on aquatic algae was not performed. In a Growth Inhibition Test with Lemna sp. according to OECD Guideline 221 and Commission Regulation (EC) No 761/2009, Annex VI, C.26 the LOEC for growth rate and biomass were determined to be > 0.591 mg/L. The 7-d NOEC of the test item both for growth tate and biomass was determined to be 0.591 mg/L (geom.mean measured).
Toxicity to microorganisms
No data on toxicity to aquatic microorganisms were available for the registration substance itself. Therefore, a read across from the structural analogue Yellow 22 (CAS 90268-98-7) was conducted.
In an Activated Sludge, Respiration Inhibition Test according to OECD Guideline 209 with the read across substance Yellow 22 (CAS 90268-98-7), no influence on the specific respiration rates up to 1000 mg/L were shown. The EC50 (3h) was > 1000 mg/L and the NOEC (3h) was 1000 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.
