Additional information

One experimental study is available investigating the short-term effects of the substance to aquatic invertebrates (Börschig & Härtel, 2016). The study was performed according to the OECD guideline 202 and GLP with the water flea Daphnia magna, as test species. Concentrations of nominal 0.54, 0.70, 0.91, 1.18, 1.54, 2.0 mg/L including a test medium control were tested under static conditions. Verification of test concentrations was performed using liquid chromatography.The recovery rate at test end after 48 hours was almost 100%.Therefore, all reported results refer to nominal concentrations. Immobilisation of Daphnia magna was observed after 24 and 48 h resulting in an EC50 (48 h) of 1.29 mg/L (95% CI: 1.20 – 1.38 mg/L). All validity criteria were met.
