Additional information
A summary of an outdated test is available: the short-term toxicity to fish (Oncorhyncus mykiss) was investigated, according to an internal method. Due to insufficient documentation for assessment, the reliability of the data cannot be judged. Rainbow trout were exposed to concentrations of test item ranging from 20 to 200 mg/l for 48 hours, and were monitored for mortality.The LC50value after 48 hours was indicated to be 120 mg/l, based on nominal concentrations of test item.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
