PFAS Explained: Risks, Sources, and What You Need to Know

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been used in a wide range of industrial and consumer products since the 1940s. They are resistant to heat, water, and oil, which makes them useful for a variety of applications, including:

* Non-stick cookware

* Food packaging

* Waterproof clothing

* Carpets and furniture

* Firefighting foam

* Industrial solvents

* Personal care products

PFAS have been found to be persistent in the environment and can accumulate in the human body. They have been linked to a number of health problems, including:

* Cancer

* Birth defects

* Immune system dysfunction

* Thyroid disease

* Liver damage

* Kidney damage

PFAS contamination is a serious public health concern. The U.S. Environmental Protection Agency (EPA) is taking steps to address PFAS contamination, including:

* Setting health advisories for PFAS in drinking water

* Conducting research on the health effects of PFAS

* Cleaning up PFAS contamination at Superfund sites

* Working with other countries to address PFAS contamination

You can help to reduce your exposure to PFAS by:

* Avoiding products that contain PFAS, such as non-stick cookware and food packaging

* Filtering your water if you are concerned about PFAS contamination

* Eating a healthy diet, including plenty of fruits, vegetables, and whole grains

* Getting regular exercise

* Avoiding contact with firefighting foam

If you are concerned about PFAS exposure, talk to your doctor.
