Description of key information
LC50>180 mg/l
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 180 mg/L
Additional information
The available literature study on Direct Red 81 was used as a key study and an LC50 value of > 180 mg/l was derived.
In the Clariant study of 2002 a similar substance was tested on freshwater fish at the limit dose of 100 mg/L. At this concentration no adverse effects were observed, so an LC50 value >100 mg/L was derived.
In Synthesia study of 2001 another similar substance was tested and based on the test conditions an LC50 value of > 100 mg/l was derived.
The conclusion that DRED81 is not toxic to fish is confirmed by the key study and by the supporting studies available.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
