This is in the form of fluorinated chemicals(PFASs). These are usually favored for their grease repellant properties but can be harmful to our health according to the study.
According to a news release that accompanied the report, PFASs are also used to give water-repellent, stain-resistant, and non-stick properties to consumer products such as furniture, carpets, outdoor gear, clothing, cosmetics, and cookware.
The dangers they pose are grave and the studies that have observed the chemicals, have linked them to kidney and testicular cancer, elevated cholesterol, decreased fertility, thyroid problems and changes in hormone functioning as well as adverse developmental effects and decreased immune response in children.
Previous studies have shown that the chemicals can migrate from the packaging into the food you eat. According to Laurel Schaider, a research scientist at Silent Spring Institute, the extent of the migration depends on the temperature of the food, the type of food and how long the food is in contact with the paper.
"And it depends on which particular chemical is in the packaging," Schaider says.
Although these long-term PFASs have been phased out over time, what has remained is the shorter chain compounds, which are thought to not last long in the human body.
The only problem is that these shorter chain compounds have not been studied and consumers are exposed to them frequently.
