Additional information

One study is available investigating the short-term toxicity to the freshwater fish Oncorhynchus mykiss according to the OECD Guideline 203 (Sayers, 2009). The test species were exposed to nominal test concentrations of 6.3, 13, 25, 50 and 100 mg/L under flow-through conditions. After the study period of 96 h a LC50 of 35 mg/L resulted based on the mean measured concentrations.
