Salmon officials confirm first application of rotenone in Miramichi watershed

After years of protest, a pesticide has been released in the Miramichi watershed as part of a project to eradicate the invasive smallmouth bass. Salmon conservation groups confirm Sept. 8 marked the first application of Noxfish II, a chemical that includes rotenone. It was released in Lake Brook and approximately 15 kilometres of the Southwest Miramichi River.

QUÉBEC, Jan. 15 2020 /CNW Telbec/ - Atrazine is one of the most widely used pesticides in North America. Researchers at the Institut National de la Recherche Scientifique (INRS) have developed a new method to degrade it that combines a new nanostructured material and sunlight.  Atrazine is found throughout the environment, even in the drinking water of millions of people across the country. Conventional water treatments are not effective in degrading this pesticide. Newer processes are more effective, but use chemicals that can leave toxic by-products in the environment.
