Additional information

To determine the toxicity of the multi-constituent substance Tinuvin 292 to fish, a GLP study according to OECD Guideline 203 using Danio rerio as test organism was carried out. Based on the nominal concentration a LC50 (96 h) 0.9 mg/L was determined [BASF SE 2010]. This result is supported by non-GLP fish test performed with Lepomis macrochirus following the procedures of the OECD guideline 203. In this test a LC50 (96) of 0.97 mg/L (measured) was observed [Ciba-Geigy Ltd. 1984].
