Study Reveals PFAS Contamination in Wisconsin Bald Eagles
by Samuel Garduño, age 16
Per- and polyfluoroalkyl chemical compounds, more commonly known as PFAS or forever chemicals, are odorless and tasteless compounds known to be produced in the US since the 1940s. What many people don’t realize, however, is that they are significantly more common than speculated. They are found in our air and water; stain-resistant materials, clothing, carpets, nonstick cookware, food packaging, firefighting foam; and so many other everyday essentials. Although PFAS are extremely common, scientists are still learning all of their effects.
Wildlife isn’t exempt from the threat of PFAS. Although testing has prioritized bald eagles, Wisconsin has also examined other wildlife, including fish, deer, waterfowl, and small mammals. Bald eagles are a prime candidate, as they are an apex predator of the food chain and a prized, almost sacred, animal amongst the American public. Since bald eagles are at the top of the food chain, their blood will show a presence of PFAS, metals, pesticides, and contaminants that amass through indirect and direct exposure. What happens in the environment parallels what affects humans. [Read More]
