RECHERCHE / S-T ACTUELLE

Évaluation des effets des contaminants sur des populations de poissons, la structure des communautés et l'état reproductif du poisson

  • Effets des effluents d'eaux usées urbaines dans les milieux récepteurs du Canada
  • Effets physiologiques nuisibles des hormones naturelles et synthétiques ainsi que des produits pharmaceutiques à l'origine de perturbations du système endocrinien chez des poissons à l'état sauvage
  • Échantillonnages sur le terrain visant à déterminer les répercussions sur des populations de poissons exposés aux effluents de sables bitumineux dans le nord de l'Alberta, aux effluents d'usines de pâtes et papiers et au ruissellement agricole
  • Liens entre une altération de la santé des poissons et des changements dans la structure de leurs communautés
  • Assesment de la santé des poissons à côté de l'exploitation des sables bitumineux
  • Évaluation des effets cumulatifs à l'échelle des bassins versants
