Federal Contaminated Site Risk Assessment in Canada: Supplemental Guidance on Human Health Risk Assessment of Indoor Settled Dust
This guidance document entitled Federal Contaminated Site Risk Assessment in Canada: Supplemental Guidance on Human Health Risk Assessment of Indoor Settled Dust was prepared to provide guidance to custodians of federal contaminated sites.
While Health Canada has used Human Health Risk Assessment principles to develop guidance documents and risk-based decisions for many years, there are no standard assumptions and methods for risk assessment of indoor settled dust at federal contaminated sites in Canada. This document is intended to provide custodians with guidance on the key issues and methods used to assess potential health risks associated with chemicals from contaminated sites that may impact indoor settled dust in view that indoor settled dust can be an important environmental media for exposure to contaminants.
This document provides standardized methodology, exposure parameters and equations that can be used to derive human health-based dust screening concentrations and to assess indoor dust contaminants at federal contaminated sites. It gives more technical information than Health Canada's Human Health Detailed Quantitative Risk Assessment guidance document and reflects the results from extensive internal and external consultation.
The Federal Contaminated Sites Action Plan (FCSAP) is a program of the Government of Canada designed to achieve improved and continued 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.
