PFAS: What You Need to Know About These Toxic Chemicals

PFAS: What You Need to Know About These Toxic Chemicals

PFAS, or “forever chemicals,” are a group of man-made chemicals that have been used in various consumer products since the 1950s. These chemicals are known for their ability to resist heat, oil, and water, making them useful in a wide range of applications. However, their persistence in the environment and potential health risks have raised serious concerns.

What are PFAS?

PFAS stands for per- and polyfluoroalkyl substances. They are a large group of synthetic chemicals with a unique molecular structure that makes them very stable and resistant to breakdown. This stability is what earned them the nickname “forever chemicals” because they can persist in the environment for a very long time, potentially for thousands of years.

Where are PFAS Found?

PFAS are found in a wide variety of products, including:

• Non-stick cookware
• Food packaging
• Firefighting foam
• Clothing and carpets
• Paints and varnishes
• Cosmetics and personal care products

Due to their widespread use, PFAS have contaminated our environment, food, and water. They have been detected in soil, air, and drinking water sources across the globe.

Health Risks of PFAS

The Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) have linked PFAS exposure to a number of health risks, including:

• Cancer
• Liver damage
• Immune system suppression
• Hormonal changes
• Birth defects
• Decreased fertility
• Developmental problems in children

The extent of PFAS’s impact on human health is still being investigated, but the evidence suggests that even low levels of exposure can pose serious health risks.

What Can We Do?

There are several things we can do to reduce our exposure to PFAS:

• Choose products that are PFAS-free.
• Use reusable water bottles and containers.
• Avoid using non-stick cookware that is not labeled as PFAS-free.
• Support policies that limit the use and production of PFAS.

The EPA is working to regulate PFAS and reduce their presence in our environment. However, more research is needed to fully understand the health risks of these chemicals and develop effective strategies for reducing exposure.

Conclusion

PFAS are a group of persistent and potentially harmful chemicals that have contaminated our environment and food sources. Their widespread use has led to significant health concerns, and more research is needed to determine the full extent of their impact. By reducing our exposure to PFAS and supporting policies that limit their use, we can protect our health and the environment.
