Perfluoroalkyls, which are chemicals used to keep grease from leaking through fast food wrappers, are being ingested by people through their food and showing up as contaminants in blood.
Perfluoroalkyls are stable, synthetic chemicals that repel oil, grease, and water. They are used in surface protection treatments and coatings for packages.
The specific chemicals studied were polyfluoroalkyl phosphate esters (PAPs), which are the breakdown products of the perfluorinated carboxylic acids used in coating the food wrappers.
Common Dreams reports:
"The researchers used the PAP concentrations previously observed in human blood together with the PAP and PFCA concentrations observed in the rats to calculate human exposure to the chemical perflurooctanoic acid, PFOA."
