Disruptores endocrinos en el medio ambiente: caso del 17-α-etinil-estradiol
Abstract
In last years endocrine disruption constitutes one of the most important research lines on Ecotoxicology. Associations between reproductive disorders in aquatic organisms and exposure to anthropogenic substances (household, agricultural or industrial origin), which reach the aquatic compartment, have been established. At the present work, endocrine disruption caused in aquatic organisms by the synthetic oestrogen 17-α-ethynyl-estradiol, which is conducted towards aquatic environment by sewage treatment plant effluents, is shown.La disruption endocrine est une des lignes de recherches les plus importantes dans les dernières années dans le domaine de l’Ecotoxicologie. Il n’y a pas mal d’évidences de bouleversements de la reproduction chez les organismes aquatiques associée à une exposition préalable aux substances d’origine anthropogénique (domestique, agricole ou même industriel) qui atteindrent le compartiment aquatique. Dans ce travaille on aborde la disruption endocrine causé dans les organismes aquatiques par l’oestrogène synthétique 17-α-ethynyl-estradiol, qui est véhiculé dans l’environnement aquatique à travers des effluents des stations d’épuration des eaux résiduelles.
