Quick takeaways
Forever chemicals, which do not break down in the environment, are accumulating in water supplies and the human body, leading to negative health effects like cancers, complications in pregnancy, and altered liver function.
Approximately 50% of drinking water in the United States contains forever chemicals, highlighting the need for societal actions such as phasing out these chemicals and implementing suitable regulations to avoid constant exposure and significant health risks.
Deep dives
Forever chemicals and their impact on health and the environment
Forever chemicals, a class of industrial chemicals used in consumer products and military applications since the 1940s, have been a growing concern. These chemicals, known as forever chemicals due to their inability to break down in the environment, are now accumulating in water supplies and in the human body, leading to negative health effects. Studies have shown an increased incidence of cancers, complications in pregnancy and childbirth, reduced immune response and response to vaccines, elevated cholesterol, altered liver function, and potential effects on hormones and reproductive health. The manufacturers of these chemicals have been slow to address the hazards, and almost 50% of drinking water in the United States has been contaminated by these forever chemicals. Phasing out these chemicals and cleaning up contaminated areas are necessary steps to protect human health and the environment.
The ubiquity of forever chemicals and the challenges of avoidance
Forever chemicals are widely used in consumer products such as waterproof coatings, pizza boxes, microwave popcorn bags, and military applications. These chemicals are both water heating and oil hating, making them useful for various purposes. However, their pervasiveness makes it difficult for consumers to avoid exposure and make informed choices. A recent report estimated that around 20,000 consumer products and approximately 50% of drinking water in the United States contain forever chemicals. The constant exposure to low concentrations over time poses a significant health risk, and avoiding these chemicals requires actions at the societal level, including phasing them out and implementing suitable regulations.
Addressing forever chemicals through research and potential solutions
Researchers, such as Northwestern University Chemistry professor Will Dictel, are working toward solutions to combat forever chemicals. One approach focuses on developing new materials to purify water, specifically polymers made from corn byproducts that effectively remove these chemicals to undetectable levels. Another breakthrough involves a reaction that breaks down forever chemicals under mild conditions, yielding safe byproducts. While these methods show promise, they are partial solutions to be combined with removal steps from water and further decommissioning methods. The scale and effectiveness of these findings, along with other research exploration such as applying energy or chemicals to break down forever chemicals, highlight the need to both eliminate these pollutants and invest in clean-up efforts. Governmental interest and funding from agencies like the Environmental Protection Agency and the Department of Defense demonstrate recognition of the urgency and importance of addressing forever chemicals.
Northwestern Chemistry Professor Will Dichtel joins us for an eye opening discussion on the dangers and pervasive threat of "Forever Chemicals." We explore the chemicals’ adverse effects and the steps necessary to mitigate their presence especially in our drinking water. Get the facts first on Morning Wire.
