Description of key information
A reliable, nominal 48h-EC50 of 14.5 mg Ba/L has been reported by Biesinger and Christensen (1972), using the cladoceran Daphnia magna as test organism.

Additional information
The reported 48h-EC50 of 14.5 mg Ba/L by Biesinger and Christensen (1972) for Daphnia magna is based on nominal test concentrations, using the soluble BaCl2 as test substance. The followed test procedure in this 1972 -study was well described and test conditions (eg.g. test medium composition) were properly identified.
No reliable data were identified for the marine compartment
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
