PFAS
Per- and Polyfluoroalkyl Substances (PFAS) are a large, diverse group of synthetic chemicals that have been used in industry and consumer products worldwide since the 1940s. Known as “forever chemicals” due to their extreme persistence, they resist degradation and accumulate in the environment and human bodies.
Key Characteristics
- Persistence: Virtually indestructible in the natural environment; do not break down easily.
- Ubiquity: Found in soil, water, air, and living organisms globally.
- Applications: Historically used in non-stick cookware, stain-resistant fabrics, firefighting foams, and food packaging.
Health & Environmental Impact
- Bioaccumulation: Accumulate in humans and wildlife over time.
- Toxicity: Linked to various health issues including cancer, liver damage, and immune system suppression.
- Water Contamination: Major concern for drinking water supplies due to leaching from industrial sites and landfills.
Recent Research & Strategies
- Removal Technologies: Focus on advanced filtration and chemical breakdown methods to mitigate contamination Toxic PFAS in Water: Contamination, Health Risks, and Removal Strategies.
- Regulatory Trends: Increasing scrutiny and potential bans on specific PFAS compounds.
