Impact/Purpose:
Industrial producers and users of per- and polyfluorinated alkyl substances (PFAS) have been a major source of chemical contamination due to historical releases of legacy PFAS. Following the general phase-out of legacy PFAS such as PFOA/PFOS, industrial usage has shifted to alternative PFAS and it has been the domain of non-targeted analysis (NTA) to identify replacement species. As such, over the last several years the office of research and development has applied non-targeted analytical approaches to the analysis of industrial effluent and contaminated environmental media (e.g. groundwater) provided by our state and regional partners to investigate the identity and quantities of legacy and emerging PFAS chemistries. This talk will provide an overview of NTA approaches for PFAS monitoring and identification of emerging PFAS contaminants along with some example case studies.
Description:
Recent advances in analytical technologies (such as high-resolution mass spectrometry) have enabled the development of emerging workflows for non-targeted analysis (NTA) in a number of important application areas. This session will focus on presenting current efforts in federal government laboratories (NIST, FDA, EPA, and CDC) to incorporate NTA methods for the enhanced screening of samples to identify and monitor new target analytes in a proactive manner.
