Federal contaminated site risk assessment in Canada: Interim Guidance on Human Health Risk Assessment of Non-cancer Effects Resulting from Less-Than-Chronic Exposures at Federal Contaminated Sites

This guidance document entitled "Federal Contaminated Site Risk Assessment in Canada: Interim Guidance on Human Health Risk Assessment of Non-cancer Effects Resulting from Less-Than-Chronic Exposures at Federal Contaminated Sites" was prepared to provide guidance to custodians of federal contaminated sites.

This guidance includes a tiered assessment framework, which outlines several key principles, scientific rationale, and steps for assessing human health risks to contaminants with non-cancer endpoints at federal contaminated sites in Canada where less-than-chronic or intermittent exposure is identified.

The information in this document will help to standardize risk assessments and provide guidance to risk assessors on relevant data required in human health risk assessment reports to enable technical review.

This document supplements previous guidance presented in the Health Canada Federal Contaminated Sites Risk Assessment in Canada: Part V- Guidance on Human Health Detailed Quantitative Risk Assessment for Chemicals (DQRAChem).

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.
