Scientists have recently conducted a study that has drawn attention to potential risks associated with toxic chemicals known as per- and poly-fluoroalkyl substances (PFAS) in products used by individuals during menstruation. The presence of these substances, often referred to as “forever chemicals,” has raised concerns within the scientific community and the general public. The findings suggest that certain menstrual products might contain PFAS, which researchers believe could have been intentionally added.
The study has prompted discussions about the safety and transparency of ingredients in products designed to provide comfort and convenience during menstruation. Despite the purpose of these items, researchers note that labels often lack comprehensive information about their composition.
During the study, which is currently undergoing peer review, more than 100 menstrual products were analyzed for the presence of fluorinated compounds associated with harmful PFAS. These substances are commonly used in various household goods, such as non-stick cookware, stain repellents, and firefighting foam. PFAS are known for their resistance to breaking down in the environment and their capacity to accumulate in the human bloodstream, leading to them being termed “forever chemicals.”
Prior research has already highlighted potential health risks associated with exposure to PFAS, including concerns about their impact on cancer development.
The latest study uncovered the presence of PFAS chemicals in a range of menstrual products, including tampons, pads, and period underwear. Interestingly, researchers also detected PFAS in unexpected items such as school uniforms. The pathways through which these substances enter the body remain uncertain and warrant further investigation.
Graham Peaslee, a professor at the University of Notre Dame and lead researcher, emphasized that PFAS are known to have both human and environmental toxicity. He noted their persistent nature, their ability to accumulate over time, and their potential health impacts.
Notably, the study found that while some menstrual products did not contain detectable levels of PFAS, others exhibited high concentrations. Total fluorine, an indicator of PFAS, was identified in the wrappers of certain pads, specific types of tampons, and the outer layers of period underwear. Concentrations in some cases reached levels of up to several thousand parts per million total fluorine.
Researchers speculated that PFAS might have been intentionally incorporated into some products to provide moisture-resistant properties. This could serve to keep the products dry and prevent leakage. For instance, the outer layer of period underwear might utilize PFAS to contain blood and avoid staining outer clothing.
The study’s findings have sparked discussions about the necessity of using PFAS in menstrual products, particularly considering the availability of alternatives that do not rely on these compounds.
The full details of the study, including the range of products affected and the extent of PFAS presence, are expected to be unveiled at an upcoming American Chemical Society meeting in San Francisco. The study’s insights shed light on the importance of consumer awareness, ingredient transparency, and ongoing research to ensure the safety of products commonly used by individuals during menstruation.
