Le paraquat était non génotoxique dans la plupart des test de mutagénicité réalisé. Certains essais étaient faiblement positifs mais la conclusion générale est que le paraquat est non mutagène. | |
Effets endocriniens peu probables

Rien dans la base de données n'indique que le paraquat puisse causer des effets endocriniens. | |

Il n'y avait aucune évidence de sensibilité accrue chez les petits des rats dans une étude sur la reproduction d'une durée de 2 générations. La dose sans effet pour la reproduction était plus élevée que la dose causant une toxicité systémique. | |

Dans quatre études effectuées sur des rats et des souris, il n'y avait pas de sensibilité accrue des fœtus comparativement aux mères après une exposition in utero. Même si aucune étude n'a été réalisée chez une autre espèce qu'un rongeur, l'ensemble des données suggère l'absence de risque sur le développement. | |

Puisque le paraquat n'est pas un inhibiteur des cholinestérases, il ne produit pas de signes toxiques ressemblant à un effet cholinergique et qu'il n'affecte pas les systèmes nerveux central et périphérique, aucune étude n'était requise.
