The objectives of this research project are to: (1) develop sensitive and selective analytical methods for determining toxic and estrogenic sewage-derived organic contaminants in the marine environment; and (2) use the developed methods to conduct a comprehensive study of the fate and distribution of these compounds in impacted environments.
High performance liquid chromatography-electrospray mass spectrometry methods will be developed for the determination of the three classes of contaminants to be studied: nonylphenol ethoxylates, quaternary ammonium surfactants, and steroid hormones (E1, E2, EE2). Full method development will include optimization of extraction and cleanup techniques, determination of chromatographic conditions, and exploration of matrix effects on signal response in the electrospray process. The developed methods will be used to study the fate of specified analytes in a sewage-impacted, urban estuary. Specifically, levels of contaminants will be quantified in surface sediments, dated sediment cores, sewage effluent, suspended particles, and surface waters. From this survey, sources and sinks will be quantified, and the distribution and behavior of the pollutants within the estuary will be determined spatially and temporally.
