Description of key information
Low short-term toxicity to fish.
Key value for chemical safety assessment
Additional information
Short-term toxicity of the substance to fish was assessed in 2 experimental studies. Few details on experimental procedures and results were available, thus reliability of available data could not be ascertained. No data on substance solubility in test media and characteristics of test solutions was available. In all cases, effect levels were above the solubility limit in water.
In a study from 1973, following method FC 2.463 (1/5/1973) group of 8 fish were exposed to 20, 200 and 1000 mg/l for 48 h. Test sample was ca. 40 % dye and dispersing agents. Mortality was recorded starting at 200 mg/l; at 1000 mg/l all fishes were dead. Overall:
TL0 = 20 mg/l
TL50 = 340 mg/l, equivalent to 136 mg/l as a.i.
TL 100 = 1000 mg/l
In a study from 1986, conducted on Brachydanio rerio following indications in ETAD 103, no mortality was recorded after 96 h at dose of 100 mg/l using a test sample containing 35.4 % dye and remaining mainly as dispersants. Therefore, no LD50 could be determined and LD0 was identified as 100 mg/l, equivalent to 35.4 mg/l a.i..
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.
