ABSTRACT
As focus expands beyond water and soil, laboratories face an urgent need to monitor volatile PFAS in air and consumer products, driving demand for robust, flexible analytical workflows capable of addressing an increasingly broad range of volatile and semi-volatile fluorinated compounds in air. This presentation will highlight learnings from standard method implementation and research projects that utilise TD-GC-MS for the identification of volatile PFAS.
Case studies will include industrial applications such as the characterisation of products of incomplete destruction (PIDs) associated with PFAS remediation and thermal treatment processes, aligned with US EPA OTM-50 methodologies, stack emissions and landfill gas. In addition, ambient air monitoring for environmental impact assessment will be discussed with relation to developing CEN practices.
Indoor air applications will also be covered in the context of human health concerns, with reference to ASTM D8560 and ASTM D8591, demonstrating approaches for assessing PFAS emissions in occupied spaces. Additional examples will explore PFAS emissions from consumer materials within the home and food contact materials.
