Additional information

A GLP-compliant OECD 202 guideline study with Daphnia magna is available for Albrite CIX(N) (Tobor-Kaplon, 2017). The batch of ALBRITE CIX(N) tested was an amber liquid with a purity of 32.06% w/w and completely soluble in test medium at the concentrations tested. A correction (factor 3.12) was made for the purity of the test item. Concentrations are expressed as pure item (p.i.).

Twenty daphnids per group (5 per replicate, quadruplicate) were exposed to an untreated control and to 100 mg p.i./L in the limit test. In addition, ten daphnids per group (5 per replicate, duplicate) were exposed to 0.10, 1.0 and 10 mg p.i./L in the combined range-finding test. The total exposure period was 48 hours and samples for analytical confirmation of exposure concentrations were taken at the start and at the end of the test. Samples taken from the limit concentration were analysed. The measured concentrations in the 100 mg p.i./L test group were 102 and 97 mg p.i./L at the start and at the end of the test, respectively. Results were therefore based on analytically confirmed nominal concentrations. The study met the acceptability criteria prescribed by the study plan and was considered valid. The 48h-EC50 exceeded 100 mg p.i./L, based on analytically confirmed nominal exposure concentrations.
