PFAS, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals used in various industrial and consumer products. They are known for their ability to repel water and grease, making them popular in non-stick cookware, food packaging, and waterproof clothing. Because they are extremely stable, PFAS do not break down easily in the environment, leading to their nickname, 'forever chemicals.'
These substances matter for health because they have been linked to several health concerns. Studies suggest that exposure to PFAS can lead to serious conditions, including certain cancers, liver damage, and immune system effects. As they accumulate in the human body and the environment, understanding their impact is crucial for public health and safety.
In the body, PFAS can disrupt normal hormonal functions and may interfere with immune responses. The long-term presence of these chemicals can lead to potential health issues, but the exact mechanisms of how they affect human health are still being researched.
It is important to be aware of PFAS due to their widespread use and persistence in the environment. Efforts are being made to reduce their usage and find safer alternatives to protect public health and the environment.
