"Forever Chemicals" PFAS Contamination: What You Need to Know and How to Reduce Exposure

Per- and polyfluoroalkyl substances (PFAS) are a growing concern for public health. These man-made chemicals are incredibly persistent, meaning they don't break down easily in the environment and can accumulate in our bodies over time. PFAS are found in a wide range of products, from non-stick cookware to firefighting foam, leading to widespread exposure. This article explores PFAS contamination, potential health risks, and ways to reduce your exposure.

What are PFAS and How Are We Exposed?

PFAS are a group of human-made chemicals known for their water, oil, and heat resistance. This makes them desirable for a variety of consumer and industrial products, including:

• Firefighting foam

• Food packaging

• Nonstick cookware

• Stain repellents for carpets and clothing

• Waterproof clothing
  

These products can release PFAS into the environment, contaminating drinking water, soil, and air. We can then be exposed through:

• Drinking contaminated water: This is the most common way people are exposed to PFAS.

• Eating contaminated food: PFAS can get into food from packaging or from crops grown in contaminated soil.

• Breathing contaminated air: PFAS can be released into the air from manufacturing facilities or from using certain products.

• Breastmilk: PFAS can pass from mother to baby through breastmilk.
  

Health Concerns Linked to PFAS Exposure

Studies are ongoing, but research suggests a link between PFAS exposure and several health problems, including:

• Decreased immune response in adults and children

• High cholesterol and other lipid abnormalities

• Reduced birth weight and developmental delays

• Increased risk of kidney cancer

• Possible increased risk of other cancers, liver problems, thyroid issues, and ulcerative colitis
  

Should I Get Tested for PFAS?

Currently, there's no routine recommendation for PFAS blood testing for everyone. However, the National Academies of Sciences suggests testing may be beneficial for those with:

• Occupational exposure: Firefighters and others who work with PFAS-containing materials.

• Residential exposure: People living in communities with documented PFAS contamination in their drinking water.

• Proximity to contamination: Those living near PFAS manufacturing facilities or waste sites.
  

PFAS Blood Test Results and Next Steps

The National Academies of Sciences report proposes a possible approach based on blood test results:

• Below 2 ng/mL: No adverse effects expected.

• 2-20 ng/mL: Potential adverse effects, especially for pregnant women. Clinicians should advise reducing exposure and screen for conditions like high cholesterol and high blood pressure.

• Above 20 ng/mL: Higher risk of adverse effects. In addition to the above recommendations, consider thyroid function tests and monitoring for signs of kidney and testicular cancer and ulcerative colitis.
  

Keep in mind:

• There's currently no way to remove or speed up the excretion of PFAS from the body.

• PFAS blood tests may not be covered by insurance.
  

Reducing Your PFAS Exposure

While we can't completely eliminate PFAS exposure, there are steps you can take to reduce it:

• Drink clean water: If you're concerned about PFAS in your drinking water, consider using a filter certified to remove PFAS. You can also get your water tested.

• Minimize processed foods: Processed foods are more likely to contain PFAS from packaging materials. Opt for fresh fruits and vegetables whenever possible.

• Cook with alternative cookware: Avoid using non-stick cookware that may contain PFAS. Opt for stainless steel or cast iron alternatives.

• Read labels: Look for products labeled "PFAS-free" when possible.

• Reduce use of stain repellents: Consider using stain-resistant fabrics that don't require additional repellents.
  

By staying informed and taking steps to limit exposure, you can help protect your health from PFAS contamination.
