Per and Polyfluoroalkyl substances, known as PFAS constitute a class of 1,000s of man-made chemicals.  These chemicals are used in products such as food packaging, cleaning products, personal care products and many other consumer-based items.  PFAS can be found all over the world and have been linked to a variety of health effects.  People can be exposed to PFAS by breathing, drinking, eating or touching materials that contain these hazardous substances.  Studies have shown a link between PFAS and many types of cancers, pregnancy and reproductive problems, high cholesterol, and other health effects yet to be fully studied.

Tisch Environmental has been in the forefront of PFAS research and sampling methods in ambient air.

Our products have been used in several research studies to collect PFAS in ambient air samples.  Our line of polyurethane foam samplers (PUF samplers) can be used to collect volatile organic compounds using EPA method TO-13A.  This method has been found to be effective in the collection of PFAS in ambient air.
