Impact des eaux de ruissellement sur des communaut\u00e9s embl\u00e9matiques des lacs alpins : Que sait-on ? Peut-on agir ?<\/h3>\n\n\n\n

L\u2019omble chevalier, esp\u00e8ce embl\u00e9matique des lacs alpins reste \u00e0 un niveau bas depuis une dizaine d\u2019ann\u00e9es, malgr\u00e9 des efforts de repeuplement et d\u2019am\u00e9lioration de la qualit\u00e9 des eaux. Quelles sont les causes : L\u2019augmentation de la temp\u00e9rature de l\u2019eau des lacs du fait du changement climatique ? Une contamination des esp\u00e8ces par des mol\u00e9cules, seules ou en cocktail, provenant des eaux de ruissellement ?  <\/p>\n<\/div>\n\n\n\n

PCB, poussi\u00e8res de pneu, compos\u00e9es de caoutchouc et de nombreux additifs dont la 6PPDq rejoignent le s\u00e9diment des zones littorales lacustres et impactent les organismes aquatiques. Quel effet sur ces populations et leurs descendances ? La hausse de temp\u00e9ratures acc\u00e9l\u00e8re-t-elle le ph\u00e9nom\u00e8ne ?<\/p>\n\n\n\n

<\/div>\n\n\n\n

Partons \u00e0 la d\u00e9couverte des processus en cours<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n

3 actions de recherche ont \u00e9t\u00e9 conduites dans le contexte de la ZABR, par deux laboratoires des deux Savoies, le Carrtel et Edytem. Elles ont permis de :<\/p>\n\n\n\n

    \n
  • Montrer l\u2019impact de l\u2019exposition de l\u2019omble chevalier et sa descendance aux PCB<\/li>\n\n\n\n
  • Analyser les effets d\u2019une exposition pr\u00e9coce des \u0153ufs et alevins \u00e0 des particules d\u2019usure de pneus<\/li>\n\n\n\n
  • Comprendre les effets additifs -temp\u00e9rature<\/li>\n<\/ul>\n\n\n\n

    Elles interrogent sur les approches scientifiques \u00e0 encourager : \u00e9tude des impacts de mol\u00e9cule \u00e0 mol\u00e9cule, \u00e9tude des effets cocktail.<\/p>\n\n\n\n

    Elles apportent des connaissances pour envisager ensemble des solutions. <\/p>\n\n\n\n
