This guidance document (Federal Contaminated Site Risk Assessment in Canada: Toxicological Reference Values (TRVs), Version 4.0) is a companion to Federal Contaminated Site Risk Assessment in Canada: Guidance on Human Health Preliminary Quantitative Risk Assessment (PQRA), and to Federal Contaminated Site Risk Assessment in Canada, Part V: Guidance on Human Health Detailed Quantitative Risk Assessment for Chemicals (DQRAchem). This guidance was prepared to provide guidance for custodians of federal contaminated sites.
Toxicological reference values (TRVs) are prescribed by a variety of national and international agencies for the purpose of characterizing risks associated with exposure to environmental contaminants. For the assessment of potential health risks posed by substances found at federal contaminated sites in Canada, the TRVs provided in this guidance should be employed.
The document was updated as identified in the Summary of Revisions section.
The Federal Contaminated Sites Action Plan (FCSAP) is a program of the Government of Canada designed to achieve improved and continuing federal environmental stewardship as it relates to contaminated sites located on federally owned or operated properties, or non-federal lands for which the federal government has accepted full responsibility.
