Emerging Contaminants: Perfluorinated Alkylated Substances PFAS
PFAS are a class of synthetic fluorinated chemicals used in many industrial and consumer products, including defense‐related applications. They are persistent, found at low levels in the environment, and bio‐accumulate.
The sources which can release significant quantities of PFAS to the environment are various, it could be, industrial and municipal wastewater treatment plants (e.g. from textile industry, chrome‐plating industry, among others), landfill leachate treatment plants, fire‐fighting incidents and fire‐fighting training areas (e.g., at airports, fuel production, and storage facilities) and landfills. Human exposure to PFAS is mainly by ingestion of contaminated food or water. These compounds are not metabolized, bind to proteins (not to fats) and are mainly detected in blood, liver, and kidneys. Elimination of PFOS, PFHxS and PFOA from the human body takes some years, whereas elimination of shorter chain PFAS is in the range of days, that is why EPA is primarily concern with long chain PFAS compounds. Concern around the environmental effects of PFAS use began in the late 1990s when it was realized that, due to their resistance to biodegradation, PFOS and PFOA were ubiquitous in various biological (wildlife and humans) and environmental (water bodies) matrices. For determination, solid phase extraction and liquid chromatography/tandem mass spectrometry (LC/MS/MS) is used for the majority of PFAS compounds. Specific precautions have to be taken in the sampling of environmental media since PFAS adsorb strongly to glass. Teflon‐containing materials can lead to increased background level. Currently, the most appropriate material for sampling seems to be polyethylene or polypropylene.
Dr. Harry Behzadi is currently Vice President of Business Development for SGS‐EHS North America. Most recently he was the Vice President of Operations, for TestAmerica Inc Eastern region and prior to that responsible for the west. Before joining SGS. He was VP of operations, and Corporate Technical Director for Accutest Laboratories, Inc. Since 1994, Dr. Behzadi had spearheaded growth and expansion of Accutest Corporation in the Southeast and beyond to the West Coast. He started Southeast division in 1995 and developed the lab from a handful of employees to one of the largest environmental laboratory in the South with staff 90+ strong. He began his career over 30 years in the pharmaceutical industry and since then he has been responsible for laboratory management, analytical method development, professional training and QA/QC in both the environmental and pharmaceutical industries. He has navigated multiple laboratories through certification and NELAP accreditation process, Dept. of Defense and Various Fortune 500 companies. His expertise encompasses all aspects of the environmental testing business including technical and operations management, new method development, acquisitions, operations integration, sales and business development.
