Abstract: This seminar will focus on the assessment of PFAS by targeted and non-targeted analysis (NTA) methods using offline and online solid phase extraction approaches coupled to LC-MS/MS and high-resolution mass spectrometry (Q-Exactive Orbitrap MS), respectively, for a more comprehensive PFAS characterization in environmental samples from South Florida. We will provide insights on PFAS distribution in tap, surface water and biota and NTA method performance using different data processing methods (Compound Discoverer v.3.3 and FluoroMatch v2.1). The identification of non-traditionally monitored PFAS and some prospects for the semi-quantitation of the tentatively identified features using a global calibration curve will be discussed.

 Bio: Natalia Soares Quinete has a B.Sc. in chemical engineering and a PhD in environmental analytical chemistry from Brazil. She is an assistant professor at Florida International  University (FIU) in the Department of Chemistry and with the Institute of Environment. Her research focuses on understanding the sources, distribution and fate of emerging contaminants, such as PFAS and phthalates, in different environmental and biological compartments and their potential impacts to humans and animals. She has been working on the development of targeted and non-targeted analysis methods using mass spectrometry for the identification and prioritization of contaminants of concern in the environment.
