OVERVIEW
PFAS are man made chemicals that don’t break down easily in the environment or in our bodies. Because of this, they build up over time and can cause serious problems. PFAS have been linked to health issues like cancer, liver damage, weakened immune systems, and problems in child development. They also pollute oceans, rivers, and soil, harming animals, especially marine life, and throwing off the natural balance of ecosystems. Their long-lasting nature and widespread use makes PFAS a serious concern for both people and the planet.
Research Questions
In what ways are people most commonly exposed to PFAS?
PFAS can be harmful to people because they stay in the body for a long time and can affect how it works. Over time, being exposed to PFAS may raise the risk of cancer, hurt the liver, mess with hormones, weaken the immune system, and cause growth problems in kids. Since these chemicals don’t break down easily, even small amounts can add up and become a problem, especially if they’re in drinking water, food, or everyday products.
What makes PFAS harmful to human health?
People usually come into contact with PFAS by drinking water that's been polluted, eating fish from dirty water, or using things like non stick pans, waterproof clothes, or fast food wrappers. PFAS can also be in household dust or in products like makeup and lotion. These chemicals don’t leave the body easily, so even small amounts can build up over time.
How do PFAS end up in oceans and other bodies of water?
PFAS get into oceans and other waters when they wash off from factories, landfills, or things we use at home and go down drains or into rivers. They can also come from firefighting foam used at places like airports. Because these chemicals don’t break down, they spread and stay in the water for a long time.
