Answer: Highly persistent man-made chemicals that hardly degrade in natural environment
Notes: Researchers have developed a rapid lab-based method detecting Forever Chemicals (PFAS) in food packaging, water, and soil within three minutes. PFAS, a family of over 4,700 highly persistent synthetic chemicals, were first developed in the 1940s and are present in various consumer products. Known for their indestructible carbon-fluorine bonds, PFAS cause pollution during production, contaminating air, water, and soil.
