Applicant's summary and conclusion

Interpretation of results:
Category 3 based on GHS criteria
Conclusions:
La partie inorganique de la substance à enregistrer (Cobalt II) apparait comme nocive (DL50 par voie orale comprise entre 50 et 300 mg/kg de poids corporel) pour les rats Wistar dans les conditions de test utilisées.
Executive summary:

Du cobalt II (chlorure de cobalt dihydratö) a été administrée à des groupes de rats Wistar mâles et femelles par intubation gastrique. Une DL50 de 418 mg/kg de poids corporel a été établie pour le chlorure de cobalt (anhydre). Ceci correspond à une DL50 de 190 mg/kg de poids corporel pour le cobalt divalent, les calculs étant basés sur les masses moléculaires.
