1. What Are PFAS?
1-1. Definition and Basic Characteristics
PFAS (Per- and Polyfluoroalkyl Substances) are a group of synthetic chemicals used in manufacturing due to their water- and grease-resistant properties. They have been widely used since the 1940s in everyday products like non-stick cookware, water-resistant fabrics, and even firefighting foams.
However, their strength is also their biggest problem: PFAS do not break down in nature, earning them the nickname “forever chemicals.”
1-2. Where Can You Find PFAS?
PFAS are everywhere! They’re in:
- Non-stick pans (Teflon coating)
- Waterproof clothing (like raincoats)
- Fast-food wrappers (grease-resistant coatings)
- Firefighting foam (used at airports and military bases)
- Cosmetics (certain long-lasting makeup products)
Because they don’t easily degrade, they accumulate in soil, water, and even human bodies over time.
2. How Do PFAS Affect the Environment?
2-1. Water Contamination
PFAS can easily enter the environment through industrial waste, firefighting foam runoff, and landfill leaks. Once in the water system, they spread quickly and contaminate drinking water.
Many cities worldwide are now facing serious water contamination issues due to PFAS pollution. Even remote areas are not safe, as PFAS travel through rivers and groundwater.
2-2. Impact on Wildlife
Animals that consume PFAS-contaminated water also absorb these chemicals into their bodies. Studies show that PFAS exposure in wildlife can lead to:
- Reproductive issues
- Developmental problems in young animals
- Changes in immune system function
2-3. Soil and Air Pollution
PFAS can be found in the air and soil as well. When products containing PFAS degrade (such as clothing and packaging), these chemicals leach into the ground and eventually reach crops and livestock. This means that PFAS can even enter our food supply.
3. How Do PFAS Affect Human Health?
3-1. The Health Risks of PFAS Exposure
Research shows that prolonged exposure to PFAS can cause serious health problems, including:
- Cancer: Some PFAS chemicals are linked to kidney and testicular cancer.
- Hormonal Disruptions: PFAS interfere with the endocrine system, which regulates hormones.
- Immune System Weakening: Studies suggest that PFAS reduce the body’s ability to fight infections.
- Liver Damage: Long-term exposure can lead to liver disease.
- Developmental Issues: PFAS can affect children’s growth and development, leading to lower birth weights and delayed puberty.
3-2. How Do People Get Exposed?
People can absorb PFAS through:
- Drinking contaminated water
- Eating food grown in PFAS-contaminated soil
- Using household products containing PFAS
- Inhaling airborne PFAS particles
Since PFAS accumulate in the body over time, even small amounts can be harmful in the long run.
