Additional information
In a publication by Vidakovic-Cifrek, Z. et al. EFFECTS OF CACL2 AND CABR2 ON GROWTH, PHOTOSYNTHETIC PIGMENTS AND ION ACCUMULATION IN DUCKWEED, the two higher concentrations (0.075 and 0.1 mol/l) of all three tested samples caused disturbed water content in plants after 14 days of cultivation.
In a static test, alga, Skeletonema costatum, was incubated for 72 hours in the presence of sodium bromide solution at 5 different concentrations. While growth and growth rates were reduced in the presence of sodium bromide solution, the percentage inhibition in growth rate remained below 50% at all time points, even at the highest concentration of sodium bromide solution of 1000.0 mg/L, unlike the reference substance which gave 60.7 % growth inhibition after 48 hours at a concentration of 1.5 mg/L. All EC50 and NOEC values were determined to be above this 1000.0 mg/L sodium bromide solution threshold.
Read across from NaBr to CaBr2 is possible due to the full dissociation of both compounds in water. Na+ and Ca2+ are not toxic in the concentration ranges where Br- is toxic. Therefore only the Br- is responsible for the toxicity effects.
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.
