L’industrie minière au Québec : situation, tendances et enjeux

For several decades, Northern Québec has been exploited by mining companies for its mineral resources, yet, research documenting the effects of toxic stress on fish health in subarctic environments remains limited. In this study, one lake directly affected by mining activities in the Schefferville area, two lakes close to mining facilities in the Fermont and Schefferville areas, and one reference lake were sampled for water, sediment and fish. Our results suggest that manganese bioaccumulation induced an oxidative stress in Catostominæ, as demonstrated by the positive relationships between manganese concentrations and catalase activity and 8-hydroxy-2’deoxyguanosine concentrations, as well as the negative relationship with glutathione peroxidase activity (both catalase and glutathione peroxidase activities being biomarkers of antioxidant capacities and 8-hydroxy-2’deoxyguanosine an indicator of DNA oxidative damage). Similarly, selenium bioaccumulation was positively correlated with 8-hydroxy-2’deoxyguanosine concentrations in Salmoninæ. These results suggest a prooxidant role of excess selenium and manganese, and highlight the interspecific variability of fish responses to contaminated areas around historical and current iron ore mining operations.

Accès à l’information : un enjeu de la participation citoyenne au Québec face aux projets miniers en région éloignée

Dans le contexte québécois, bien que le Bureau d’audiences publiques en environnement (Bape) jouisse d’une bonne crédibilité en tant qu’institution de participation citoyenne (Gauthier & Simard, 2011), son efficacité fait curieusement défaut dans le cas de l’industrie minière où, malgré certains cas de forte opposition citoyenne, aucun projet d’exploitation n’a été refusé par le gouvernement (Deneault & Sacher, 2012). Cet article pose un regard critique sur les conditions de la participation citoyenne en regard de l’examen de projets miniers au Québec, particulièrement en région éloignée en analysant la mobilisation citoyenne découlant de l’annonce en 2017 du projet Authier Lithium de la minière Sayona Québec Inc. (SQI) en Abitibi.
