Relevant and reliable data that could be used for classification for short-term toxicity for freshwater fish were retrieved for 4 different species. The LC50s ranged from 1.5 mg Co/L for Onchorhynchus mykiss to 85 mg Co/L for Danio rerio. Test results were obtained in experiments that followed international accepted guidance and were based on measured levels of dissolved cobalt as cobalt dichloride. No relevant and reliable data that could be used for classification for short-term toxicity for marine fish were identified. Thus, no LC50 values were derived for short-term toxicity for marine fish.
high quality studies were included in the acute toxicity to aquatic fish
database for freshwater fish. Four different species were represented in
the studies, primarily distributed between the Danio rerio,
Oncorhynchus mykiss and Pimephales promelas species. Median
lethal concentration (LC50) values ranged from 1.5 mg Co/L (Oncorhynchus
mykiss, CDI, 2008a) to 85 mg Co/L (Danio rerio, CDI, 2008b).
one study was identified which examined the acute toxicity of cobalt to
marine fish species, Fundulus heteroclitus.
study was designated as category RL3 because the level of study
documentation was incomplete and the reported values were based on the
nominal (i.e., unmeasured) cobalt concentrations. Thus, no acute aquatic
fish tests were judged sufficient to carry forward in subsequent risk
