Site Prioritization for Risk Assessment

One of the primary goals of the POPs toolkit is to provide countries with the capacity to perform simple Human Health Risk Assessments. When it comes to cleaning up multiple sites in a country the questions arise: where to begin?  Which sites should be a priority for a risk assessment? 

In this section, two semi-quantitative tools are presented that allow the user to determine which sites should be assessed and then to prioritize sites based on their potential for causing unacceptable risks to humans and/or the natural environment.

The purpose of the site prioritization is to classify contaminated sites based on their need for further action. Further action usually means risk assessment.  The tools provided ask the user a series of questions regarding: contaminant characteristics, off-site migration potential, exposure and socio-economic factors. Then, based on the answers provided, calculates a total score for that site.

POPs Toolkit users who are looking to prioritize and manage their pesticide stockpiles should view more information about the FAO's obsolete pesticide programme.

The site prioritization tools are based on principals derived from the Canadian National Classification Tool for contaminated sites (CCME 2008). While the tools are applicable to any contaminated site, a greater emphasis has been put on POP’s related contaminant issues.
