Manganese and its compounds
These substances were identified for action under the Chemicals Management Plan (CMP). The draft assessment focuses on the manganese moiety and therefore considers manganese in its elemental form, manganese substances, and manganese released in dissolved or particulate form. As such, the draft assessment considers all manganese-containing substances beyond the 11 identified as priorities for assessment, listed in the table below.
