Description of key information

The 96 hour LC50 was greater than 100 % v/v saturated solution. The No Observed Effect Concentration was superior or equal to 100 % v/v saturated solution.

Key value for chemical safety assessment

Additional information

The acute toxicity of the test material to Oncorhynchus mykiss was investigated in accordance with the standardised guidelines OECD 203 and EU Method C.1 under GLP conditions. It was assigned a reliability score of 1 in accordance with the criteria set forth in Klimisch (1997).

In a limit test, seven fish were exposed to an aqueous solution of the test material at a single concentration of 100 % v/v saturated solution for a period of 96 hours at a temperature of 14 to 15 °C under semi-static test conditions. The number of mortalities and any sub-lethal effects of exposure in each test and control vessel were determined 3 and 6 hours after the start of exposure and then daily throughout the test until termination after 96 hours. No mortality or sub-lethal effects were seen throughout the duration of the exposure.

Under the conditions of this study, the 96 hour LC50 was greater than 100 % v/v saturated solution. The No Observed Effect Concentration was superior or equal to 100 % v/v saturated solution.
