The test substance, Centralit, was tested in acute immobilisation test on Daphnia magna.The test was performed according to method C.2 – Daphnia sp. Acute Immobilisation Test, Council Regulation (EC) No. 440/2008, published in O.J.L 142, 2008.Since the test substance is poorly soluble in dilution water at concentrations needed for the test, the saturated solutions of the test substance in dilution water were prepared.The full test was performed in range of test substance nominal concentrations 10 - 49 mg.L-1. Samples for analytical determination were taken at the beginning and at the end of the test.
analytical results showed that the test substance Centralit was stable
in dilution water at conditions of the test, therefore the nominal
concentrations were used for all evaluations and results.
EC50 (48h) for daphnia magna was used for C&L and for Chemical Safety
