These substances were identified for action under the Chemicals Management Plan (CMP). The assessment focused on the thallium moiety and therefore considers all thallium-containing substances that may release thallium, as well as thallium in its elemental form and thallium released to the environment in dissolved, solid or particulate forms. This includes 5 thallium-containing substances identified as priorities for assessment, which are listed in the table below.
