PFASs are common environmental contaminants that have been used in products such as water and stain repellents, nonstick cookware, surfactants such as detergents and wetting agents, and polymers (plastics).

They tested an egg sample from each studied nest for PFAS concentrations and compared those results to how well the rest of the eggs hatched.<o:p></o:p></span></p><p style='line-height:140%'><span style='font-size:10.0pt;line-height:140%;font-family:"Georgia","serif";color:black'>The USGS-led study suggested that tree swallow hatching rates declined at high PFAS concentrations (as high as 150-200 nanograms per gram of wet weight), which are lower than the concentrations that have affected other bird species in laboratory studies. This difference may be due to behavioral effects or other factors not accounted for in the laboratory studies. It could also mean that tree swallows are especially sensitive to these toxins.<o:p></o:p></span></p><p style='line-height:140%'><span style='font-size:10.0pt;line-height:140%;font-family:"Georgia","serif";color:black'>PFASs can enter the environment through contaminated groundwater and surface water runoff from plants that manufacture or use PFAS products, from household waste water that passes through treatment plans, and from airborne chemicals settling on the ground.
