Additional information
One study addressing short-term toxicity to aquatic invertebrates is presented in the dossier.
Short-term toxicity to aquatic invertebrates.001 – daphnia -1983 – key: Acute toxicity to Daphnia magna was assessed in a manner similar to OECD guideline 202 (Daphnia sp. Acute Immobilisation Test) not according to GLP (pre-dates GLP requirements). The study was conducted in triplicate closed glass flasks containing nominal concentrations of 0, 46, 99, 210, 460, or 1000 mg/L. Immobility was recorded at 24 and 48 hours and probit analysis was used to calculate the EC50. The 48-hour EC50 for Immobility was determined to be 190 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
