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.

Additional risk characterization document

The Additional Risk Characterization Document in Support of the Draft Screening Assessment for Zinc and its Compounds: Pulp and paper sector exposure and risk characterization was published on June 25, 2021. The document contains new information pertaining to releases of zinc from the pulp and paper sector identified since publication of the draft screening assessment.

The document has been published to provide the public with the opportunity to comment on the new information, prior to it being considered in the final screening assessment of zinc and its compounds, and if appropriate, the corresponding proposed risk management approach.

Comments or information submitted with respect to the risk characterization document must cite the title of the document, along with the date of publication, and can be provided to the Minister of the Environment until August 24, 2021, using one of the following methods:

In accordance with section 313 of the Canadian Environmental Protection Act, 1999, any person who provides information in response to this publication may submit with the information a request that it be treated as confidential.

Date Activity
June 2022 Anticipated publication of the final screening assessment and proposed risk management approach.
June 25, 2021 Publication and start of 60-day public comment period on the additional risk characterization document.
June 29, 2019 Publication and start of 60-day public comment period on the draft screening assessment and the risk management scope. The related notice was published in the Canada Gazette, Part I: Vol. 153, No. 26.
