Forever Chemicals Concept Map
A group of synthetic chemicals known as per- and polyfluoroalkyl substances (PFAS), also referred to as Forever Chemicals, are resistant to degradation and can persist in the environment for a long time. These chemicals are commonly used in various industrial and consumer products due to their water and grease-resistance properties. However, they have raised concerns due to their potential adverse effects on human health and the environment.
Summary
Forever Chemicals, also known as per- and polyfluoroalkyl substances (PFAS), are synthetic chemicals resistant to degradation, commonly used in various products for their water and grease resistance properties.
However, concerns arise due to their potential adverse effects on human health and the environment. The advantages of PFAS include their useful properties in industrial and consumer products, while the disadvantages stem from their persistence in the environment, leading to potential harm.
Proponents of PFAS include chemical manufacturers, while opponents consist of environmental activists and health organizations. PFAS have been found in various wildlife and even in the blood of Arctic polar bears, showcasing their far-reaching impact.
PFOS and PFOA are similar substances with differences in persistence and health risks. PFOS, for instance, is known for its environmental persistence and potential health effects, leading to restrictions in its use.
