Zinc and its compounds
Information sheet
These substances were identified for action under the Chemicals Management Plan (CMP). This screening assessment focuses on the zinc moiety and therefore considers all zinc compounds on the Domestic Substances List (DSL) that may release zinc as well as zinc in its elemental form, and zinc released in the environment in dissolved, solid or particulate forms. It includes, but is not limited to the 75 substances identified in the table below.
