Answer:
Explanation:Hello :) I hope the explanation helps, PFAS chemicals are called "forever chemicals" because they do not break down easily in the environment and can persist for a very long time. The term "forever chemicals" is used to describe PFAS because they have very strong carbon-fluorine bonds that are difficult to break down through natural processes such as biodegradation, photolysis, or hydrolysis. This makes them highly resistant to degradation and therefore they can persist in the environment for decades or even centuries. In addition to their long lifespan, PFAS chemicals are also highly mobile and can travel long distances in the environment. They can enter the soil, water, and air and accumulate in the food chain. They have been detected in wildlife, human blood, and breast milk. The longevity and persistence of PFAS chemicals make them a concern for human and environmental health. They have been linked to a range of health effects including cancer, immune system dysfunction, and developmental delays, among others. Due to their ability to accumulate in the environment and in living organisms, they are a subject of increasing regulatory scrutiny and efforts to reduce their use and release into the environment. You are welcome to ask me any questions :)
