Description of key information

LC50 (96 h) = 24.3 mg/L for Brachydanio rerio Hamilton-Buchanan, Teleostei, Cyprinidae (OECD TG 203), study Röderer (1990)

Key value for chemical safety assessment

LC50 for freshwater fish:
24.3 mg/L

Additional information

The value for the key parameter is based on the lowest observed value in a study considered to be reliable (key study: Röderer, 1990) using zebrafish Brachydanio rerio Hamilton-Buchanan, Teleostei, Cyprinidae. The second study (Buccafusco, 1981) using bluegill support the key parameter by reporting a similar LC50 (96 h) of 27 mg/L for CTC.
