They pose a serious threat.
Concerns about PFAS, also known as “forever chemicals,” in the food and water supply are valid, according to Dr. Leonardo Trasande, a leading expert in children’s environmental health. Dr. Trasande, a professor at NYU Grossman School of Medicine, emphasized the need for more serious action from governments to address the issue. PFAS (perfluoroalkyl and polyfluoroalkyl substances) are synthetic chemicals used in a variety of consumer products, and they are difficult to break down due to their strong carbon-fluorine bonds.
These chemicals have been widely used since the 1940s in products like nonstick cookware, fire-extinguishing foam, and water-resistant clothing. Unfortunately, PFAS have made their way into the human body through food and water, with nearly all Americans carrying some level of these chemicals in their bloodstream. PFAS contamination has also been detected in public water supplies, leading to significant health concerns, particularly for children.
Children are especially vulnerable to PFAS exposure because they consume more food, water, and air relative to their body size, and their developing organ systems are more sensitive to harmful chemicals. While the U.S. Environmental Protection Agency has set limits for PFAS in drinking water, Dr. Trasande believes stronger regulations are necessary. He highlighted how countries like France have taken more decisive steps, such as implementing a full ban on PFAS, and urged the U.S. to follow suit.
In the meantime, Dr. Trasande advises individuals to reduce their exposure to PFAS by avoiding nonstick cookware in favor of alternatives like cast iron or stainless steel, and by minimizing the use of plastics, especially in microwaves or dishwashers. Improving ventilation in homes can also help reduce the buildup of dust that may contain PFAS and related chemicals. These steps, combined with more robust government action, are crucial to minimizing the risks associated with PFAS.
