Additional information
Two studies are available for the toxicity of Pigment Yellow 34 on fish.
1. In a study according to German standard DIN 38412 Leuciscus idus was exposed to C.I. Pigment Yellow 34 for 96 hours. The test solutions contained undissolved test material and was cloudy and coloured. No mortality or abnormalities were observed. Complete observation of symptoms was difficult due to the cloudiness of the solution. The LC50 was > 10000 mg/l (BASF AG, 1988, reliability 2).
2. In a study according to OECD TG 203 Pigment Yellow 34 was tested on Onchorhynchus mykiss (rainbow trout), under GLP. The test was carried out as a limit test. A suspension of 100 mg per liter was filtered (0.45 micrometer) to remove particles. There was no significant mortality, abnormal appearance or behaviour of rainbow trout exposed t the filterable portion of the nominal solution of 100 mg/L. Thus the 96h-LC50 of Pigment Yellow 34 is > 100 mg/l.
Measured concentrations of lead and chromium were 0.19 - 0.26 mg Pb/L and 0.20 - 0.16 mg Cr/L (0 - 96 h, respectively) (Stantec Ltd 2006, reliability 1).
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).
