Conclusion on classification

Short-term aquatic toxicity data are available for three trophic levels. The lowest observed acute effect concentration is a 48-h EC50 value of 4.53 mg/L as derived from a study with aquatic invertebrates (D. magna). Long-term aquatic toxicity data are available from an algae study in which a 72 -h NOEC value of 0.536 mg/L was derived. The substance is qualified as not readily biodegradable. Based on all this information, the substance needs to be classified as Aquatic Chronic Category 2, H411 (Toxic to aquatic life with long lasting effects) according to regulation EC/1272/2008 (CLP). According to the Dangerous Substance Directive 67/548/EC, the available ecotoxicological and environmental fate data warrants classification as R51/53 (Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment).
