About PFAS

• Chemicals with carbon-fluorine bonds are extremely strong and resistant to degradation.
 • These substances can withstand grease, oil, water, and heat.
 • Applications include use in cookware, food packaging, food processing equipment, fabrics, paints, and foams.
 • Impact: They remain in the environment indefinitely, earning the nickname 'Forever Chemicals', and they contaminate air, water, and soil, while also bioaccumulating in humans and animals.
