What We Know About How 'Forever Chemicals' Affect Health
What Are Forever Chemicals?
Per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," are synthetic compounds widely used in non-stick cookware, water-resistant fabrics, food packaging, and firefighting foams. They are called "forever chemicals" due to their resistance to degradation in the environment and the human body.
Sources of PFAS Exposure
- Contaminated drinking water
- Processed and packaged foods
- Household products (e.g., stain-resistant carpets, non-stick cookware)
- Industrial emissions and occupational exposure
Health Effects of Forever Chemicals
Research suggests long-term exposure to PFAS is linked to several health issues, including:
Hormonal Disruption
- PFAS can interfere with endocrine function, impacting hormone regulation.
Increased Cancer Risk
- Studies indicate a potential link to kidney, liver, and testicular cancers.
Immune System Suppression
- PFAS exposure may reduce vaccine efficacy and weaken immune response.
Liver Damage
- Can cause liver enzyme abnormalities and contribute to liver disease.
Reproductive and Developmental Issues
- Linked to fertility problems, low birth weight, and developmental delays in children.
Metabolic and Cardiovascular Effects
- May increase cholesterol levels, risk of obesity, and high blood pressure.
Regulations and Efforts to Reduce Exposure
- The U.S. Environmental Protection Agency (EPA) has set drinking water limits for PFAS.
- Some countries have banned or restricted the use of certain PFAS compounds.
- Consumers can reduce exposure by using PFAS-free products and filtered drinking water.
Conclusion
While research on PFAS is ongoing, strong evidence suggests significant health risks associated with prolonged exposure. Regulatory actions, corporate responsibility, and public awareness are essential in mitigating these risks and reducing PFAS contamination in the environment.
