Toxic man-made chemicals that end up in the environment highlight regulation challenges Researchers at the University of New Hampshire have conducted two of the first studies in New England to collectively show that toxic man-made chemicals called PFAS (per-and polyfluoroalkyl substances), found in everything from rugs to product packaging, end up in the environment differently after being processed through wastewater treatment facilities making it more challenging to set acceptable screening levels. PFAS are persistent substances that are not easily broken down and have been linked to adverse health effects. They are found in a wide variety of industrial, commercial and medicinal products and can end up in the body, human waste and the environment. If not managed correctly, they can be further distributed around the environment in landfills, waterways and even stabilized biosolids could be applied to agricultural fields as fertilizers.
