Per- and Polyfluoroalkyl Substances (PFAS)

Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, are a group of synthetic chemicals that have been used in many everyday products since the 1940s. These include things like firefighting foam, non-stick pans, water and stain-resistant fabrics, fast food packaging, and personal care products. PFAS don’t break down easily, which makes them useful, but also means they stick around in our environment for a long time, earning them the nickname “forever chemicals.” Long term exposure to PFAS compounds has been associated with a variety of health impacts, including reproductive effects and cancer risk.

Neonicotinoids

Neonicotinoids, or neonics, are commonly used pesticides in agricultural and urban environments. They can be used in a variety of ways, such as seed treatments, soil treatments, foliar sprays, and topical applications. They impact a wide range of insects and other invertebrates, while being comparatively non-toxic to humans and other mammals. Recent research has shown that neonics have spread throughout our environment beyond their area of application, impacting our ecosystems and raising concerns about possible health impacts.

If you are interested in learning more about neonics, or want to help create educational resources to raise awareness about neonic research or best use and practices, please check out the Wisconsin Neonicotinoid Workgroup. The goal of this group is to support effective decision-making by fostering collaboration among researchers, conservation groups, agricultural operators and professionals, and the general public.
