Topic: Per- and Polyfluorinated Alkyl Substances (PFAS): A Review “From PFOS to GenX”DescriptionCNHHE is pleased to present Terry Obal, PhD, CChem, Chief Science Advisor, Bureau Veritas Laboratories to discuss the state of the science around PFAS chemicals.
Perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and related per- and polyfluorinated alkyl substances (PFAS) are recognized by environmental practitioners and regulatory bodies around the world as compounds of environmental concern. These persistent chemicals are found widely in the environment. The ubiquity of these compounds in a wide range of environmental and biological matrices, compounded with their chemical properties and studies suggesting human toxicity have resulted in increased public concern.
In April 2021, the Government of Canada published a notice of intent in the Canada Gazette considering activities that would address the broad class of PFAS.
This presentation will provide a brief overview of the science around PFAS including:
• PFAS as contaminants of emerging environmental concern
• Exposure and toxicity
• Sampling and analysis considerations – Soil, water, tissue and air
• Treatment and remediation – What are our options?
• The future of PFAS in the environmental marketplace
