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 2 Daphnia species and the crab Barythelphusa guerini . The lowest short-term EC50 is observed on Daphnia pulex: 42 µg Cd/l (single measured value). The EC50 values ranged between 38 and 1900 µg Cd/l. Species geomean for Daphnia is 130 µg Cd/l.

Key value for chemical safety assessment
