Event Title
Ecological Screening Assessment of Selected Surfactants under the Government of Canada’s Chemicals Management Plan
Presentation Abstract
Under the Chemicals Management Plan (CMP), the Government of Canada is assessing and managing, where appropriate, the human health and ecological risks of substances. Building on the first 2 phases of the CMP (2006-2015), 1550 substances have been identified for the third phases of the CMP. These substances will be assessed over the coming five years.
Surfactants known as the alkyl aryl sulfonates/linear alkyl benzene sulfonates (LABS) and derivatives, are among those identified as priorities for action in the third phase of the CMP (starting 2016). The selection of these substances is based on the categorization process completed in 2006. A screening assessment for these substances will be conducted under the Canadian Environmental Protection Act, 1999 (CEPA). the Government of Canada will apply wight of evidence and precaution in decision-making to determine whether the substance may be toxic as defined in Section 64 of the Act.
For the ecological risk assessment, all available data for various media will be considered, including chemical analogues for "read-across" purposes and computer models. Where data is limited, conservative assumptions will be applied in the ecological risk assessment for factors such as the potential for theses substances to degrade or metabolize; the potential for these substances to bioaccumulate; and the potential for these substances to cause harm to biota in the environment.
A 60-day public comment period will follow the publication of the draft screening assessment for these substances.
This poster provides a description of the ecological assessment process for the alkyl aryl sulfonates/LABS and derivatives under the CMP.
