Applicant's summary and conclusion
- Interpretation of results:
- Category 3 based on GHS criteria
- Conclusions:
- La partie organique de la substance à enregistrer (2,4-pentanedione) apparait comme nocive (CL50 par inhalation comprise entre 2.0 et 10.0 mg/L d'air pour les vapeurs) pour les rats Wistar dans les conditions de test utilisées.
- Executive summary:
Des groupes de 5 rats albinos Hilltop-Wistar mâles et 5 femelles [HLA (WI) BR] ont été exposés pendant quatre heures à des vapeurs générées dynamiquement de 2,4-pentanedione. Les concentrations testées étaient de 628, 919, 1231 et 1508 ppm (correspondant à 2619, 3823, 5133 et 6288 mg / m³, respectivement), analysées simultanément pendant chaque exposition de 4 heures par chromatographie en phase gazeuse. Les résultats de ces tests indiquent que la CL50 dynamique de 4 heures pour la partie organique de la substance à enregistrer (2,4-pentanedione) est de 1224 ppm (correspondant à 5.104mg / L) màles et femelles combinés.
