Pregnancy is a joyous journey filled with anticipation and preparation. But amidst the excitement, it's crucial to be aware of potential environmental threats that can impact your unborn child's health. Per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals," are a growing concern due to their widespread presence and potential risks during pregnancy. 

This article explores how these man-made compounds can affect your baby's development and offers practical steps you can take to minimize exposure.

PFAS and Pregnancy - Understanding the Risks

PFAS are a growing concern for pregnant women due to their widespread presence in the environment and their potential to harm a developing fetus. These man-made chemicals are incredibly persistent, resisting breakdown in the environment and accumulating in our bodies over time.

A recent Emory University study provided groundbreaking insights into the risks of PFAS exposure during pregnancy. The study, the first of its kind, detected these compounds in the blood of newborns. It linked prenatal exposure to an increased likelihood of preterm or early-term births. 

Mothers with higher PFAS levels were 1.5 times more likely to deliver a baby born three weeks or more before their due date and 1-2 weeks early.

This research also achieved a significant first by finding measurable levels of PFAS in newborn blood samples. This confirms that babies are exposed to these chemicals while still in the womb, likely by crossing the placenta from the mother's bloodstream. 

Furthermore, the study identified biological markers in newborns that suggest PFAS exposure may disrupt critical processes like tissue growth and hormone function. Future research aims to determine if detecting these markers in pregnant women's blood could predict the risk of preterm birth.

These findings highlight the vulnerability of developing babies to PFAS and the potential consequences for their health. By understanding these risks, pregnant women can take steps to minimize their exposure and create a healthier environment for their unborn child.

Sources of PFAS Contamination

Pregnant women may encounter these compounds through various sources, raising concerns about potential health impacts on their unborn children. Understanding these sources is crucial for minimizing exposure.

Contaminated drinking water 

One of the primary sources of exposure is contaminated drinking water. PFAS can infiltrate municipal water systems and private wells, often originating from industrial discharge, firefighting foam (AFFF), and waste sites. 

According to The Guardian, PFAS contamination in the Great Lakes basin’s water highlights the pervasive nature of these chemicals. In this region, which contains nearly 95% of the nation’s freshwater, these compounds are present in the air, rain, and water. Precipitation, including rain, is a significant contributor to the lakes’ contamination, suggesting that similar mechanisms could affect water sources elsewhere.

Certain Food Packaging Materials

PFAS are commonly used in food packaging materials to make them resistant to grease and water. This includes products such as microwave popcorn bags and greaseproof liners found in fast food packaging. The chemicals can leach into food, leading to potential ingestion.

Stain and Water-Resistant Treatments 

Many household items, including clothing, carpets, and furniture, are treated with PFAS-based stain and water-resistant coatings. These treatments can release these compounds into the air and household dust over time.

Household Dust

PFAS can accumulate in household dust from treated surfaces, leading to incidental ingestion or inhalation. This dust can be a significant source of exposure, particularly in homes with older or treated products.

Contaminated Beef and Dairy 

These chemicals can enter the food chain through contaminated land. According to Michigan Advance, sewage sludge with PFAS used as fertilizer can contaminate pasture grass, which cattle consume. This contamination can be transferred to beef and dairy products. 

Additionally, free-range chickens might ingest these compounds through the soil, affecting egg PFAS levels. PFAS levels in milk and eggs can decrease once exposure sources are removed.

AFFF - A Significant Source of PFAS Contamination

Aqueous Film-Forming Foam (AFFF) is a significant source of contamination in some communities. This firefighting foam, used extensively since the 1960s, releases “forever chemicals” into the environment during training exercises and real-world fire situations. This legacy of AFFF use has resulted in PFAS infiltrating soil and water supplies, impacting nearby residents including pregnant women.

Recently, there has been a notable increase in AFFF lawsuits against its manufacturers such as 3M and DuPont. These lawsuits claim that these companies were aware of the dangers of PFAS for decades but did not alert users or the public. 

According to Forbes, this situation arises from two main issues. First, public awareness of the health risks associated with PFAS was delayed. The Environmental Protection Agency (EPA) only publicly acknowledged these risks in 2009.

Second, internal documents have shown that manufacturers might have known about the toxicity of AFFF as far back as the 1960s. This prior knowledge has enabled plaintiffs to argue that the manufacturers were negligent and liable for the health issues linked to AFFF exposure.

TruLaw notes that as of June 2024, over 8,270 AFFF lawsuit filings were reported. These ongoing legal battles aim to provide compensation for those who may have suffered health consequences due to AFFF exposure. 

Understanding the connection between AFFF and PFAS contamination empowers expecting mothers and communities to advocate for environmental remediation efforts.

Minimizing PFAS Exposure - Protecting Your Pregnancy

Minimizing exposure to these compounds is crucial for protecting health, particularly during pregnancy. Here are practical steps to reduce exposure:

Using Water Filters

Look for filters specifically designed to address PFAS contamination, such as activated carbon filters or reverse osmosis systems. These filters can significantly reduce contamination levels in drinking water, providing safer water for consumption and cooking.

Avoiding PFAS-Containing Products

Be mindful of products known to contain PFAS, such as non-stick cookware, stain-resistant fabrics, and certain cleaning agents. Opt for alternatives made from natural materials or those explicitly labeled as PFAS-free. This includes choosing cookware made from stainless steel or cast iron.

Reducing Processed Food Consumption

Limit intake of processed foods, which may be packaged in materials treated with PFAS to repel grease and water. Opt for fresh, unpackaged foods whenever possible, and store food in glass or stainless steel containers rather than those with non-stick coatings.

Minimizing AFFF Exposure

Stay away from areas with known AFFF contamination, such as near fire stations or industrial sites where firefighting foam has been used. If you live near such areas, consider testing your water and soil for PFAS contamination. If contamination is detected, take steps to mitigate exposure, such as using bottled water or installing filtration systems. 

Frequently Asked Questions

Can PFAS cause miscarriage?

Research suggests that high levels of PFAS exposure may be associated with an increased risk of miscarriage. These compounds can impact hormonal balance and fetal development, potentially leading to adverse pregnancy outcomes.

How to remove PFAS from the body?

Removing PFAS from the body involves reducing exposure and supporting natural detoxification processes. While there are no specific treatments, consuming a healthy diet rich in antioxidants may help minimize exposure levels and support overall health.

What supplements remove PFAS from the body?

Studies suggest that folate may help reduce PFAS accumulation in blood serum, potentially minimizing adverse effects. Folate, a B vitamin found in many foods, supports overall health and may aid in reducing exposure levels. However, more research is needed to confirm its effectiveness in detoxifying PFAS specifically.

This article explored the dangers of PFAS and provided actionable steps to empower you to create a safer environment for your baby. By understanding the sources of contamination, adopting mindful practices, and creating a cleaner home environment, you can significantly reduce your exposure.

Remember, knowledge is power. Stay informed about PFAS in your community and advocate for safer practices. Taking charge and implementing these strategies, will help you contribute to a healthier pregnancy and a brighter future for your little one.
