The presence of indoor sources for certain PFAS can cause indoor air concentrations to be higher than outdoor air concentrations. It is hypothesized consumer products and building materials contribute to human exposure of PFAS either directly (e.g. hand-to-mouth transfer) or indirectly (e.g. inhalation of suspended particles). Particulate matter, either suspended or settled, and inhalation exposure to suspended contaminated particles from semi volatile organic chemicals (SVOCs) also plays an important role in human exposure. Better understanding the transport mechanisms of these emerging contaminants between sources, air, airborne particles, house dust, and interior surfaces in the indoor environment is essential to estimating indoor exposure and developing strategies that enlighten risk assessments and policy decisions to minimize exposures and protect human health. This project is to develop methods and generate exposure-related data for emerging contaminants in articles including consumer products and building materials. The research effort will include (1) developing air sampling and analytical methods for emerging contaminants, e.g. PFAS, in the indoor environment; (2) developing methods and indoor exposure testing protocols, include but not limited to the particle formation, source-to-dust transfer, and contaminants interaction with airborne particles and settled dust; and (3) investigating the fate and transport mechanisms, collect data, and provide input parameters that will be used to inform and refine estimates of human exposures to consumer products and building materials.</span><o:p></o:p></p></td></tr><tr><td style='border:solid #5B616B 1.0pt;border-top:none;background:#FFFFDB;padding:10.6pt 10.6pt 10.6pt 10.6pt'><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:.25in'><strong><span style='font-family:"Calibri",sans-serif;color:#212121'>Geographical location of position:</span></strong><o:p></o:p></p></td><td style='border-top:none;border-left:none;border-bottom:solid #5B616B 1.0pt;border-right:solid #5B616B 1.0pt;background:#FFFFDB;padding:10.6pt 10.6pt 10.6pt 10.6pt'><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:.25in'><span style='color:#212121'>Research Triangle Park, NC</span><o:p></o:p></p></td></tr><tr><td style='border:solid #5B616B 1.0pt;border-top:none;background:#FFFFDB;padding:10.6pt 10.6pt 10.6pt 10.6pt'><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:.25in'><strong><span style='font-family:"Calibri",sans-serif;color:#212121'>High priority research areas:</span></strong><o:p></o:p></p></td><td style='border-top:none;border-left:none;border-bottom:solid #5B616B 1.0pt;border-right:solid #5B616B 1.0pt;background:#FFFFDB;padding:10.6pt 10.6pt 10.6pt 10.6pt'><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:.25in'><span style='color:#212121'>Chemical Safety for Sustainability (CSS) (Rapid Exposure and Dosimetry); ExpoCast; Air and Energy Research Program Topics 1, 2, 3 </span><o:p></o:p></p></td></tr><tr><td style='border:solid #5B616B 1.0pt;border-top:none;background:#FFFFDB;padding:10.6pt 10.6pt 10.6pt 10.6pt'><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:.25in'><strong><span style='font-family:"Calibri",sans-serif;color:#212121'>Scientific project area:</span></strong><o:p></o:p></p></td><td style='border-top:none;border-left:none;border-bottom:solid #5B616B 1.0pt;border-right:solid #5B616B 1.0pt;background:#FFFFDB;padding:10.6pt 10.6pt 10.6pt 10.6pt'><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:.25in'><span style='color:#212121'>CSS Rapid Exposure and Dosimetry Project</span><o:p></o:p></p></td></tr><tr><td style='border:solid #5B616B 1.0pt;border-top:none;background:#FFFFDB;padding:10.6pt 10.6pt 10.6pt 10.6pt'><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:.25in'><strong><span style='font-family:"Calibri",sans-serif;color:#212121'>Educational requirements:</span></strong><o:p></o:p></p></td><td style='border-top:none;border-left:none;border-bottom:solid #5B616B 1.0pt;border-right:solid #5B616B 1.0pt;background:#FFFFDB;padding:10.6pt 10.6pt 10.6pt 10.6pt'><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:.25in'><span style='color:#212121'>Doctorate degree in a science, technology, engineering, or mathematics related discipline.
