Impact of Persistent Organic Pollutants (PFAS) on Human Health Explored Through 5 Key Points

Impact of Persistent Organic Pollutants (PFAS) on Human Health Explored Through 5 Key Points

In a call to action, Dr. David Shewmon, an endocrinologist, encourages the public to be more mindful of the endocrine-disrupting chemicals (EDCs) found in everyday products, particularly those containing PFAS (per- and polyfluoroalkyl substances).

First introduced by manufacturers in the 1940s, PFAS chemicals were engineered to be strong and durable, resisting heat, oil, stains, grease, and water. Although American companies no longer manufacture PFOA and PFOS chemicals, they continue to exist in the environment and companies still produce other PFAS chemicals. The U.S. Environmental Protection Agency (EPA) has declared perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) to be dangerous substances.

Exposure to PFAS chemicals is linked to a range of potential adverse health effects. High exposure can cause problems in the body over time, including problematic thyroid function (hyperthyroidism or hypothyroidism), increased risk of various cancers (childhood acute lymphoblastic leukemia, kidney cancer, non-Hodgkin lymphoma, ovarian cancer, prostate cancer, testicular cancer, thyroid cancer), and reduced immune function.

Exposure during pregnancy can lead to reduced birth weights, lower sperm quality and count, increased risk of obesity, early onset of puberty, bone issues, behavioral changes in children.

Key health effects associated with PFAS exposure are:

• Increased cancer risk: Exposure, especially via contaminated drinking water, is linked to cancers of the kidney, prostate, digestive system (colon, esophagus, liver, gallbladder), lung, thyroid, bladder, brain, skin, and soft tissue.
• Immune system impacts: PFAS can lower immunity, reducing vaccine effectiveness, disrupting trained immunity, and altering immune cell development even prenatally.
• Pregnancy-related effects: Higher PFAS exposure is associated with increased risk of preeclampsia (high blood pressure during pregnancy) and may decrease fertility in women.
• Other chronic health issues: PFAS exposure may increase cholesterol levels and the risk of thyroid disease.

PFAS are persistent in the environment and bioaccumulate, meaning even low-level exposure can potentially have lasting health impacts. Blood tests can measure PFAS exposure but cannot predict health outcomes.

These findings are based on a combination of human epidemiological studies and animal research, with ongoing investigation to clarify mechanisms and risks at lower exposure levels.

Given their widespread presence and persistence, it's crucial for individuals to take steps to reduce their exposure. Americans are exposed to PFAS chemicals through everyday products such as clothing, cosmetics, firefighting foam, nonstick cookware, rugs, upholstery, and food packaging.

Simple ways to reduce exposure include asking local water utilities to test the water for PFAS, avoiding nonstick cookware, avoiding stain-resistant coatings on furniture and rugs, bringing glass containers for to-go food, and paying attention to local health advisories about agricultural products and drinking water.

While the health effects of PFAS typically occur slowly and subtly over time and with repeated exposure, it's essential to be proactive in minimizing exposure to protect one's health.

1. Within the realm of health and wellness, a significant concern is the endocrine-disrupting chemicals (EDCs), especially those found in products containing PFAS.
2. PFAS, or per- and polyfluoroalkyl substances, were initially introduced by manufacturers in the 1940s, known for their resistance to heat, oil, stains, grease, and water.
3. Despite American companies ceasing the manufacturing of PFOA and PFOS chemicals, these substances continue to exist in the environment, and other PFAS chemicals are still produced.
4. The U.S. Environmental Protection Agency (EPA) has identified perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) as hazardous substances.
5. Exposure to PFAS chemicals is associated with various potential health issues, including problems with thyroid function and increased cancer risk.
6. High exposure to these substances can lead to an increased risk of various cancers, such as childhood acute lymphoblastic leukemia, kidney cancer, non-Hodgkin lymphoma, ovarian cancer, prostate cancer, testicular cancer, and thyroid cancer.
7. PFAS exposure can also reduce immune function and increase the risk of chronic diseases, such as obesity, early onset of puberty, bone issues, and behavioral changes in children.
8. Exposure during pregnancy can result in reduced birth weights, lower sperm quality and count, increased risk of obesity, early onset of puberty, and other significant health issues for the child.
9. The key health effects linked to PFAS exposure are increased cancer risk, immune system impacts, pregnancy-related effects, and other chronic health issues.
10. Exposure to PFAS, particularly via contaminated drinking water, can potentially cause cancers of the kidney, prostate, digestive system, lung, thyroid, bladder, brain, skin, and soft tissue.
11. PFAS can lower immunity, reduce vaccine effectiveness, disrupt trained immunity, and alter immune cell development even prenatally.
12. Higher PFAS exposure is associated with an increased risk of preeclampsia during pregnancy and potentially decreased female fertility.
13. PFAS exposure may increase cholesterol levels and the risk of thyroid disease.
14. Given their longevity in the environment and ability to bioaccumulate, even low-level exposure to PFAS can have lasting health impacts.
15. Blood tests can detect PFAS exposure but cannot predict health outcomes.
16. Ongoing research aims to clarify mechanisms and risks associated with PFAS at lower exposure levels.
17. As PFAS chemicals are ubiquitous in everyday products, it is crucial for individuals to take measures to reduce their exposure.
18. Partial exposure methods include asking local water utilities to test the water for PFAS, avoiding nonstick cookware, eschewing stain-resistant coatings on furniture and rugs, using glass containers for to-go food, and heeding local health advisories about agricultural products and drinking water.
19. Adopting a proactive approach to minimize exposure to PFAS is essential to protect one's health, considering the slow and subtle nature of health effects that occur over time with repeated exposure.
20. The implications of PFAS exposure are not confined to health; they also extend to the manufacturing industry and environmental science.
21. Finance and retail sectors must address the presence of PFAS in their supply chains, ensuring they adopt sustainable practices and promote environmentally friendly alternatives.
22. In order to counter those persistent chemicals, new industries have emerged, like the CBD (cannabidiol) industry, offering potential therapies and treatments for various health conditions.
23. The fashion and beauty industry can incorporate organic and natural ingredients in skin-care products to mitigate the use of harmful substances like PFAS.
24. Healthcare providers in the workplace-wellness sector must educate their employees on the dangers of EDCs, promoting a culture of mindfulness and proactive preventive care.
25. Climate change contributes to the proliferation of PFAS in the environment, making it imperative for the environmental science sector to address this issue in conservation and restoration efforts.
26. In the context of energy, steps must be taken to ensure the safe production and disposal of energy resources, as they can also contribute to PFAS contamination in the environment.
27. The transportation sector should prioritize reducing emissions and implementing faster and cleaner technologies to minimize its impact on climate change and the associated increase in PFAS exposure.
28. The lifestyle, food and drink, and personal finance industries should encourage responsible consumption and educate consumers about the implications of their choices on their health and the environment.
29. Investing in businesses that prioritize environmental, social, and governance (ESG) factors and support the development of sustainable technologies is essential for wealth management, banking, and insurance.
30. In conclusion, addressing the presence of PFAS in our daily lives requires collective action, involving various industries, policymakers, and concerned citizens, fostering a sustainable and healthy future for all.
