Passive air samplers are well-suited for monitoring persistent organic pollutants (POPs) in ambient air. While the presence of POPs had been documented in Australian air, no data existed on structurally similar, halogenated natural products (HNPs), although these were frequently found in marine biota samples from Australia at levels exceeding those of anthropogenic POPs. This study reports quantitative data of the HNP 2,4,6-tr...

Per- and polyfluoroalkyl substances (PFAS) are a focus of biomonitoring studies globally. In Australia, population PFAS serum concentrations have been determined since 2002 using pooled de-identified serum samples ( n = 4800) collected from the population bi-annually, as a component of the Australian Human Biomonitoring (HBM) project. Locations of environmental PFAS contamination (‘PFAS hotspots’) are known to exist in Austral...

Purpose of Review Per- and poly-fluoroalkyl substances (PFAS) are prevalent environmental contaminants detected in materials such as soils, biosolids, and wastes. Understanding PFAS leaching is crucial for assessing risks associated with leaving impacted material in place, reuse, or disposal. However, there is limited guidance on laboratory methods to measure extent and rate of leaching. This review aims to identify the best m...
