Schematic diagram illustrating the routes of human PFAS exposure. Following production, PFAS are used in consumer products such as food packaging, cookware, water repellent clothing and non-stick fry pans. PFAS are also a main component in firefighting foam, which can leach into the environment, or are otherwise disposed of as industrial waste. Human exposure may occur through use of consumer products or from contaminated water supplies. Accordingly, environmental exposure can occur as a result of waste products contaminating waterways and soil through leaching of firefighting foam and waste from industry and consumers.
