Key value for chemical safety assessment

Fresh water fish

Fresh water fish
Effect concentration:
1 µg/L

Additional information

Although this study was performed above water solubility level, under the study conditions no toxicity to the organisms was detected and no visible effects occurred during the 96-hour test period.

In the study, the water solubility value was taken as LC50 due to technical difficulties in detection of the actual concentration of the substance in the water. In a recent water solubility study for FR-245 (2005) the water solubility of the substance was under the limit of detection in the study and was determine to be less than 1ug/l due to the same technical difficulties. The value of 1ug/l is taken as the actual water solubility value of the substance.

The substance water solubility value of 1ug/l is taken as a worst case scenario for PNEC calculation
