Final answer:
Perfluorochemicals (PFCs) are man-made chemicals that contain carbon and fluorine atoms. They are persistent in the environment and can accumulate in living organisms, leading to biomagnification. Examples of PFCs include perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS).
Step-by-step explanation:
Perfluorochemicals (PFCs) are a group of man-made chemicals that are made up of carbon and fluorine atoms. They are used in a variety of industrial and commercial applications, including as surfactants, lubricants, and water and oil repellents. Due to their unique chemical properties, PFCs are persistent in the environment and can biomagnify in the food chain, meaning that they can accumulate in the bodies of living organisms over time. Some examples of PFCs include perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS).
