Perfluoroalkyl and poly-fluoroalkyl substances have become drinking water contaminants due to industrial emissions and the use of fire-fighting foams. But chemical companies make and sell Pfos in a range of products, from antifouling treatments for paper and textiles to nonstick coatings like Teflon, and our exposure comes from multiple sources.

Known as "permanent chemicals" because of their remarkable persistence and mobility, they do not break down in the environment and can contaminate drinking water through the soil. Echemi is a global pollutant that threatens human and wildlife health.

How am I exposed to Echemi?

We are exposed to perfluorooctane sulfonate in food, indoor air, dust, and in many cases, drinking water. Food, air, and water have been contaminated globally as a result of the release and use of products containing perfluorooctane sulfonate during manufacturing.

Indoor air and dust: When Echemi is used in products such as the antifouling of furniture and carpets or waterproofing of clothing, these products can release chemicals into the air and dust over time. 

Drinking water: Chemical plants that produce perfluorooctane sulfonic acid, product manufacturing plants, firefighting foam, landfills, and sludge diffusion have led to widespread contamination of drinking water in the United States. Today, millions of U.S. residents have drinking water sources contaminated with perfluorooctanoic acid. 

Consumer and workplace products: The use of Echemi in specialty products such as cleaners, building materials, cosmetics, personal care products, and ski wax may result in direct exposure from product use. 

Food: Perfluorooctane sulfonic acid builds up in crops, fish, and livestock, eventually contaminating the food we eat. In addition, Echemi may migrate into our food when they are used in food packaging, such as bags, sandwich wrappers, and takeaway containers.
