Ranking of chemicals is a process through which decision makers decide which chemicals need to be regulated. In this paper we have analyzed in detail two issues. One is the process of ranking itself. Our opinion is that indices are not suitable to identify hazardous contaminants since indices hide information. The second issue is that the criteria used to assess a chemical might not be the best possible. Therefore, in this paper we have used a different method, based on graph theory, to rank toxic contaminants. We have also developed a method to assess which criteria are critical in ranking toxic contaminants, which could be excluded or not even measured"--Management perspective.
