Products marketed toward them are often used to repel chemicals. According to ACS Environmental Science & Technology, some water- or stain-resistant products contain PFAS, but others are labeled green or nontoxic.
Exposure to PFAS through inhalation and ingestion has been linked to a host of health concerns, including the effect of vaccines on children, cancers, and high cholesterol, according to the United States Department of Health and Prevention. However, few studies have examined whether these compounds were readily available in apparel, bedding, and furnishings that were intended to be used by them.
Interestingly, 54 of the 93 items surveyed contained fluorine, an indicator of PFAS. Of the fluorine-containing products, 18, 18 had measurable levels of PFAS. A total of 19 were found to be water-resistant or leak-proof, but these were only found in foods that had previously been labeled for water- or stain resistance. These were also found in other categories, which claimed to be nontoxic. The team concludes that these findings suggest that these substances be removed to protect children.
