We are all exposed to per- and polyfluoroalkyl substances (PFAS) in one way or another. These man-made chemicals have been used in a variety of industrial and consumer products for decades, and they are now found in the environment, our food, and even our bodies.

Sources of PFAS

PFAS can be found in a wide variety of products, including:

• Nonstick cookware: PFAS are used to create the slippery surface on nonstick cookware.
• Food packaging: PFAS are used to greaseproof and water-resistant food packaging.
• Stain-resistant carpets and upholstery: PFAS are used to make carpets and upholstery resistant to stains.
• Water-resistant clothing: PFAS are used to make clothing water-resistant and windproof.

PFAS in the Environment

PFAS can also be found in the environment, including:

• Air: PFAS can be released into the air from industrial emissions and from the use of PFAS-containing products.
• Water: PFAS can leach into groundwater and surface water from landfills, industrial sites, and wastewater treatment plants.
• Soil: PFAS can be deposited on soil from the air and from the use of PFAS-containing products.

PFAS in Our Bodies

PFAS can enter our bodies through:

• Ingestion: We can ingest PFAS by eating contaminated food or water.
• Inhalation: We can inhale PFAS from the air.
• Skin contact: We can absorb PFAS through our skin when we use PFAS-containing products.

Health Effects of PFAS

Exposure to PFAS can cause a variety of health problems, including:

• Cancer: PFAS have been linked to an increased risk of certain types of cancer, including kidney cancer, testicular cancer, and non-Hodgkin lymphoma.
• Reproductive problems: PFAS can interfere with the reproductive system, leading to problems such as infertility and birth defects.
• Developmental problems: PFAS can also cause developmental problems in children, such as learning disabilities and ADHD.
• Immune system problems: PFAS can suppress the immune system, making people more susceptible to infections.

How to Reduce Your Exposure to PFAS

There are a number of things you can do to reduce your exposure to PFAS, including:

• Avoid using PFAS-containing products: When possible, choose products that do not contain PFAS.
• Wash your hands frequently: PFAS can be absorbed through the skin, so wash your hands frequently with soap and water.
• Eat a healthy diet: Eating a healthy diet can help to reduce your exposure to PFAS. Choose fruits, vegetables, and whole grains, and limit your intake of processed foods.
• Drink filtered water: PFAS can be found in drinking water, so it is a good idea to drink filtered water whenever possible.

Conclusion

PFAS are a group of man-made chemicals that have been found in a wide variety of products and in the environment. Exposure to PFAS can cause a variety of health problems. There are a number of things you can do to reduce your exposure to PFAS, including avoiding PFAS-containing products, washing your hands frequently, eating a healthy diet, and drinking filtered water.
