National data and approaches are used for the national risk assessment, whereas the risk assessment on the roof level is based on the procedure described in this Chapter. In the national risk assessment additional substances beyond those described in this chapter may have been used. Therefore, results at the national level may differ from those given in the Roof report. (4.7.
