Assessments of the behavior and impact of chemicals in the environment typically require a multicriteria approach as a multitude of parameters has to be taken into account in order to disclose the full picture. In the present paper we demonstrate how selected partial order ranking tools can be applied as decision support. As an illustrative example a series of 14 chemicals, belonging to 4 different classes of chemicals, found in the river Main (Germany) have been assessed based on 3 parameters, i.e. volatilization, sedimentation and advection, determinative for their exposure behavior. In addition to ordinary partial order ranking more advanced tools as average ranks and dominance analysis have been applied leading to conclusions as to which class of chemicals should receive primary attention. Further, the analyses suggest directions for risk management such as pointing to specific sources for the most problematic pollutants.
Keywords: Partial Order Ranking, Hasse Diagram Technique, Average Rank, Dominance Analysis, Environmental Impact Assessment, EIA, River Main.
