Executive summary:

The EU risk assessment, as a secondary reference, cites data reported by WHO (1992) and CEC (1978) (secondary references).

LD 50 values were derived from studies in rats and mice using CdO administered orally or intra-gastrically but details on the primary studies reporting these values are not available. LD50 value was 63mg Cd/kg bw in the mouse.
