요약 | The increase in the presence of pharmaceuticals and endocrine disrupting hormones (EDCs) in the environment has had a direct impact on aquatic organisms in the environment. Estrogen hormones, one class of EDCs, have been quantified in natural so |
요약 | The goals of this dissertation were to (1) determine an optimal estrogen extraction solvent that yielded the largest E1, E2, and EE2 recovery percentages, (2) optimize separation of ten estrogen and estrogenic compounds using different stationar |
요약 | For the first objective, four organic solvents and three solid phase extraction (SPE) loading ratios were evaluated in order to determine an optimal method to extract estrogens from an agricultural soil (1.09 %TOC). Solvents used to extract the |
요약 | For the second objective, standard solutions containing ten estrogenic compounds were separated using six different stationary phase and mobile phase combinations. Three stationary phases were evaluated, C18, biphenyl, and RP-Amide, and two mobi |
요약 | For the third objective, results indicated that sorption varied between E1, E2, and EE2 and between the three soils studied. Partition coefficient values, Kd and Kf, increased with an increase in soil organic carbon concentration and vice versa, |
요약 | Finally, E1, E2, and EE2 baseline data was established for the Penn State Living Filter wastewater irrigation site, and the Sinnemahoning Creek Watershed. At the Living Filter, all three compounds were detected in groundwater well samples. Howev |
