Description of key information

The good quality short-term data that were available for all Cd-substances were considered together, since the toxicity of the Cd++ ion is key to this analysis.  
Data were available on 7 fish species. The lowest short-term EC50 is observed on Salmo Salar: 34 µg Cd/l (single measured value). The EC50 values ranged between 34 and 6470 µg Cd/l.

Key value for chemical safety assessment

Additional information

All good quality short-term data that were available for all Cd-substances were considered together, since the toxicity of the Cd++ ion is key to the hazard assessment of Cd in water.

Data were available on 7 fish species. The lowest short-term EC50 is observed on Salmo Salar: 34 µg Cd/l (single measured value). The EC50 values ranged between 34 and 6470 µg Cd/l. Toxicity was generally low with EC50 in 6 out of 7 species > 700µg Cd/l.. The results were obtained in a pH range of 6.5 -7.8. The toxicity was in general highest at lower hardness.
