Applicant's summary and conclusion
- Conclusions:
- La partie organique de la substance à enregistrer ne montre pas d'effet négatifs sur les organes reproducteurs de rats mâles et femelles.
- Executive summary:
Dans une étude d'inhalation subchronique menée chez des rats mâles et femelles F344 après exposition à 0, 100, 300 et 650 ppm (concentrations nominales, correspondant à 0, 417, 1 217 et 2 711 mg/m3), aucun signe d'effets pathologique n'ont été observé dans les testicules et l'épididyme des mâles ainsi que dans l'utérus, le col et les ovaires des femelles en
comparaison avec des animaux témoins non traités immédiatement après la fin de l'étude et après une période de récupération de 4 semaines, respectivement, révélant ainsi aucun effet négatif sur les organes reproducteurs de rats mâles et femelles. Une NOAEL de 417 mg/m3 a été établie pour la partie organique de la substance à enregistrer: la 2,4 -pentanedione.
