Yes, there is evidence to support that per- and polyfluoroalkyl substances (PFAS) can lead to adverse health outcomes in humans like: low infant birth weights, negative effects on the immune system, cancer, and thyroid hormone dysfunction. Although, we no longer make these dangerous substances in the USA anymore, other countries do & we import their products containing PFAS.
“People can also be exposed to PFAS chemicals if they are released during normal use, biodegradation, or disposal of consumer products that contain PFAS. People may be exposed to PFAS used in commercially-treated products to make them stain- and water-repellent or nonstick. These goods include carpets, leather and apparel, textiles, paper and packaging materials, and non-stick cookware.... Drinking water can be a source of exposure in communities where these chemicals have contaminated water supplies.”
Once exposed, PFAS accumulates in the body, leading to negative effects on health. Not only should we monitor PFAS levels in land, air & water and develop safety standards, we also need to develop testing to determine human exposure. We need to work on ways to decrease exposure, including denying trade of goods with PFAS.
