R. Dixon Associates - Management Resources for Health, Safety and Environment

A number of Canadian organizations, health risk analysts and health scientists, including the Toronto-based International Institute of Concern for Public Health, have been striving for years to expose the serious flaws inherent in the currently applied methodology for Human Health Risk Assessments.

Among the many weaknesses of the methodology is its inability to assess the short, medium and long-term health impact of concurrent exposures to multiple chemicals and other health stressors.

A recent critique - year 2010- carried out by COMMHEALTH - R. Dixon Associates of the Human Health Risk Assessment produced by Total E & P Canada Ltd. for its proposed new Tar Sands Upgrader in Fort Saskatchewan, Alberta, Canada, see http://www.commhealth.net/health-risk-assessment-reports/ reveals that authorities - in this case the Alberta Energy Resources Conservation Board - still refuse to accept that there are fundamental implausibilities inherent in the currently adopted HHRA methodology.

We reflect upon the presentation made 10 years ago, to the Government of Canada, by Dr. Rosalie Bertell. The document can be downloaded below.
