What exactly are PFAS chemicals?
PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals used in a variety of products due to their water and grease-resistant properties. These chemicals have been linked to serious health issues and are commonly found in everyday items like non-stick cookware, food packaging, and firefighting foam.

Why are PFAS chemicals harmful?
PFAS chemicals are harmful due to their persistence in the environment and the human body. These 'forever chemicals' do not break down easily and can accumulate over time, leading to potential health risks. Studies have shown that exposure to PFAS chemicals may result in various health issues, including cancer, immune system disorders, and developmental delays in children.

How do PFAS chemicals affect public health?
PFAS chemicals can enter the human body through contaminated drinking water, food, and consumer products. Once inside the body, these chemicals can build up and remain for long periods, increasing the risk of adverse health effects. The widespread presence of PFAS in the environment poses a significant threat to public health, prompting regulatory actions to limit exposure and protect communities.
-
What are the sources of PFAS contamination?
PFAS contamination can originate from various sources, including industrial discharges, firefighting activities, and the use of PFAS-containing products. These chemicals can leach into the soil and water, leading to widespread contamination of drinking water supplies and ecosystems. Efforts to identify and mitigate sources of PFAS pollution are essential to safeguard public health and the environment.

How can individuals reduce their exposure to PFAS chemicals?
Individuals can reduce their exposure to PFAS chemicals by avoiding products known to contain these substances, such as non-stick cookware, stain-resistant fabrics, and certain types of food packaging. Additionally, using water filters certified to remove PFAS from drinking water and supporting initiatives to regulate and monitor PFAS contamination can help minimize exposure risks.
