Description of key information
LD0 (28 d) ≥ 100 mg/kg diet.
Key value for chemical safety assessment
Additional information
One day old Japanese quails were allotted to a basis diet with 50 or 100 mg/kg of lanthanum chloride for four weeks. Feed and water was supplied ad libitum. The hatchlings were observed for mortality and changes in bofy weight and tibia mineralisation. The average percentage of mortality in the treatment and control groups during the whole period was 1.3% resulting in a LD0 ≥ 100 mg/kg diet. Furthermore the author stated that 100 mg/kg diet was the optimum concentration of lanthanum salts for increasing growth performance and for improving bone mineralization.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
