Copper and its compounds

These substances were identified for action under the Chemicals Management Plan (CMP). This screening assessment focuses on the copper moiety and therefore considers copper in its elemental form, copper-containing substances, and copper released in dissolved, solid, or particulate form. It includes, but is not limited to the 37 substances identified in the table below.

The draft SAR for copper and its compounds uses the draft Federal Environmental Quality Guidelines (FEQGs) for copper as the predicted no-effect concentration for freshwater.  The draft FEQGs for copper are simultaneously published for public review in the Canada Gazette on May 18, 2019.
