    OECD Work Related to Bees/Pollinators

    There have been reports these last years of declines in native and managed pollinators in several regions of the world. Potential factors associated with these declines are hypothesised to include habitat destruction, predators, certain agricultural practices, bee management practices, pathogens, climate change, nutrition and pesticides. There is uncertainty regarding the extent to which pesticides contribute to pollinator declines.

    Essai n° 405 : Effet irritant/corrosif aigu sur les yeux

    Cette méthode fournit des informations sur les dangers pour la santé qui peuvent résulter de l’application d’une substance d’essai (solide ou liquide et d’aérosols) sur les yeux. Cette Ligne directrice est utilisée préférablement avec des lapins albinos. La substance d’essai est appliquée en dose unique dans le sac conjonctif d’un œil. L’autre œil, non traité, servira de contrôle. L’essai initial emploie un animal ; le niveau de dose dépend de la nature de la substance à tester. Un essai de confirmation doit être fait si un effet corrosif n’est pas observé lors de l’essai initial, la réponse irritante ou négative doit être confirmée en utilisant deux animaux supplémentaires. Il est recommandé que ce soit fait de manière séquentielle, un animal à la fois, plutôt que d’exposer les deux simultanément. La durée de l’observation doit être suffisante pour évaluer pleinement l’ampleur et la réversibilité des effets observés. Les yeux doivent être observés 1, 24, 48 et 72 heures après l’application. Les scores d'irritation oculaire doivent être évalués en conjonction avec la nature et la sévérité des lésions et leur réversibilité ou leur absence de réversibilité. L’utilisation d’anesthésiques topiques et d’analgésiques systémiques pour réduire ou éviter la douleur et la détresse dans le cadre des essais de sécurité pour l'œil est décrite.

    Substitution of hazardous chemicals

    As the demand for safer chemicals grows, the field of alternatives assessment is becoming increasingly important in guiding the transition towards safer, less toxic alternatives. A major limitation that can hinder efforts is the lack of consistent criteria for defining “safer" alternatives. This guidance outlines key considerations for the identification and selection of safer alternatives.
