Additional information

Conclusion on classification

For the substance acute aquatic toxicity data are available for three trophic levels (fish, aquatic invertebrates and algae). The lowest acute toxicity value is a 96 -h LC50 of 38 mg/L in fish (O. mykiss). A chronic aquatic endpoint is available only for freshwater algae (P. subcapitata). In this species a 72 -h NOErC of 115 mg/L was determined. Additionally, the substance is not readily biodegradable. Based on all these data, the substance needs to be classified as Chronic Toxicity Category 3, H412 (harmful to aquatic life with long lasting effects) according to the CLP Regulations (EC) No 1272/2008. According to the Dangerous Substance Directive 67/548/EC, the available ecotoxicological information warrants classification as N; R52/53 (Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment).
