In an Anaerobic Aquatic Transformation study, four known metabolites of the compound under study were proposed for confirmation using HPLC-MS. This was based on retention time matches between reference standards and the metabolites found during the HPLC-RAM analyses. This study used sediments from two rivers, and two “compartments” (aqueous and sediment extract) from each sediment type were examined; providing a total of four compartments. These four compartments were used for identification of the metabolites. In the HPLC-RAM portion of the study, four metabolites were found at different levels in all the compartments. Two of the four metabolites, proposed for confirmation, were found in some compartments, whereas others required further investigation, resulting in the discovery of new metabolites. Examination of the data found these new metabolites at relative concentration levels consistent with the HPLC-RAM data. The analyses and identification of new metabolites will be presented in this poster
