QUE SIGNIFIE DIELDRIN EN ANGLAIS
Dieldrine
La dieldrine est un hydrocarbure chloré produit initialement en 1948 par J. Hyman \u0026 amp; Co, Denver, comme insecticide. La dieldrine est étroitement liée à l'aldrine, qui réagit davantage pour former de la dieldrine. L'aldrine n'est pas toxique pour les insectes; Il est oxydé dans l'insecte pour former de la dieldrine qui est le composé actif. La dieldrine et l'aldrine sont appelées d'après la réaction de Diels-Alder qui est utilisée pour former de l'aldrine à partir d'un mélange de norbornadiène et d'hexachlorocyclopentadiène. À l'origine développé dans les années 1940 comme alternative au DDT, la dieldrine s'est révélée être un insecticide très efficace et a été largement utilisé pendant les années 1950 au début des années 1970. L'endrine est un stéréoisomère de dieldrine. Cependant, c'est un polluant organique extrêmement persistant; Il ne se décompose pas facilement. En outre, il a tendance à biomagnifier en passant par la chaîne alimentaire. L'exposition à long terme s'est révélée toxique pour une très large gamme d'animaux, y compris les humains, beaucoup plus grands que les cibles d'insectes originales. Pour cette raison, il est maintenant interdit dans la plupart des pays du monde. Il a été lié à des problèmes de santé tels que la maladie de Parkinson, le cancer du sein et les dégâts immunitaires, reproductifs et du système nerveux.
