Detailed Description
USGS scientists and partners have found that tree swallow eggs exposed to elevated levels of products known as perfluoroalkyl substances are associated with a decreased chance of hatching. PFASs are common environmental contaminants that have been used in products such as water and stain repellents, nonstick cookware, surfactants, polymers and wetting agents.
