Fast Food Wrappers

Americans may be consuming fast food wrapped in paper treated with perfluorinated chemicals (PFCs) — the same chemicals used in stain-resistant products, firefighting materials and nonstick cookware, according to a new study published in the journal Environmental Science & Technology.

Researchers tested more than 400 samples of packaging materials, including hamburger and sandwich wrappers, pastry bags, beverage cups and French fry containers, and found evidence of fluorinated compounds called per- and polyfluoroalkyl substances (PFASs). Of the materials tested, these chemicals were found in 56 percent of dessert and bread wrappers, 38 percent of sandwich and burger wrappers and 20 percent of paperboard.

Previous studies have shown that these PFASs can migrate, contaminating the food and, when consumed, accumulating in the body.

“This is a really persistent chemical,” said Graham Peaslee, a professor of experimental nuclear physics in the College of Science at the University of Notre Dame, who tested the samples. “It gets in the bloodstream, it stays there and accumulates. There are diseases that correlate to it, so we really don’t want this class of chemicals out there.”

Peaslee used a novel specialized method called particle-induced gamma-ray emission (PIGE) spectroscopy, which he developed to analyze the total fluorine content of each piece of packaging. PIGE is an efficient and cost-effective way to measure the presence of chemicals like fluorine in solid samples.
