Recently Dr Sarah Richards, Principal Geoenvironmental Engineer, presented at the 39th SETAC North America conference held in Sacramento from the 4 -8 November.  

Sarah’s presentation “Observed distribution of PFOS in biota in a tropical environment” looked at the human health and ecological risk assessment of per- and poly fluoroalkyl substances stream from legacy AFFF use.

She presented her key observations from biota testing conducted across aquatic, riparian and terrestrial settings. She discussed the trends in compound contributions and total concentrations in various plants and animals throughout the environment and how that describes the way that PFAS compounds are transported through the environmental food web. The results of the biota testing have been used in ecological risk assessments to validate food web relationships, identify the most significant pathways and provide a baseline for future reference.
