Selenium - Final screening assessment and risk management approach



Certain selenium-containing substances are among those identified as priorities for action for the second phase of the Chemicals Management Plan (CMP). The selection of these selenium-containing substances for action is based on the categorization process completed in 2006.

In December 2017, the Final Screening Assessment for Selenium and its compounds was released and the related notice was published in the Canada Gazette, Part I: Vol. 151, No. 50 – December 16, 2017. The final screening assessment focuses on the selenium moiety (selenium and its compounds), and therefore includes substances containing selenium in all oxidation states (selenite, selenate, elemental, selenide), organic selenium, and all forms of selenium found in the environment. The selenium assessment encompasses all 29 selenium-containing substances on the Domestic Substances List (DSL) including those that met categorization criteria. The final screening assessment concluded that selenium and its compounds, which includes but is not limited to the 29 selenium-containing substances on the DSL, are harmful to the environment and for certain subpopulations in Canada that have higher selenium intake; however, they are not considered harmful to the general population of Canada. The substances therefore meet the criteria under paragraph 64(a) and 64(c) of CEPA 1999. A proposed risk management approach document was also released at the same time for a 60-day public comment period.

Deadline for submission of public comments on the proposed risk management approach document: February 14, 2018
