PFAS

A new study has found that toxic “forever chemicals” are absorbed by the skin.

A study found that PFAS or “forever chemical” can pass through the skin barrier. Experts had previously believed this was not an important source of exposure.

The study looked at 17 PFAS chemicals that are found in products which come into contact with skin. These include fabrics, rain gear and waterproof mascaras, foundations, etc.

Oddny Ragnarsdottir is a chemist who was the lead author in this study.

It’s typically products that are advertised as water-repellent or stain-repellent.

Ragnarsdottir stated that different PFAS chemicals have different effects on the body and the environment. However, there are some similarities between the group.

She said, “They are both oil and water soluble.” They have unique properties that make them exciting for manufacturers.

These properties can also be harmful to people’s health.

Ragnarsdottir stated that “we can eliminate them with time”. “But it could take a very long time”, he said.

According to the U.S. Environmental Protection Agency, PFAS (per- and polyfluoroalkyl compounds) are a group of chemicals that includes nearly 15,000 substances. They have been used since the 1940s in consumer and industrial products. Only a fraction of the PFAS chemicals have been thoroughly studied.

As companies are not required by law to label their products, it is difficult to determine which products contain PFAS.

Ragnarsdottir explained that people are likely to be exposed to toxic chemicals in their diets and water. However, skin contact with PFAS over time can accumulate. <a class="Link" data-cms-ai="0" href="https://pubs.acs.org/doi/10.1021/acs.est.2c02111%22%20/l%20%22:~:text=Total%20targeted%20PFAS%20levels%20in,100%25%20cotton%20than%20synthetic%20blends." A 2022 study found that school uniforms in the U.S., Canada and other countries contained high levels of PFAS.

Ragnarsdottir explained, “It is clothes that children wear for eight hours every day.” “Even if the absorption will be small, exposure, or the time spent wearing the clothing, is so long. Over time, the accumulation will increase.

Although PFAS chemicals are not found in nature, they are manufactured and can be found in many products, including food packaging, carpets, non-stick cookware, drinking water and soil.

According to the EPA, these chemicals can cause a variety of health problems including obesity, increased cholesterol, decreased fertility and vaccine efficacy. They may also reduce immune response against infections and lead to prostate, kidney, and testicular tumors.

Ragnarsdottir stated that some companies are now advertising they are PFAS free.

Ragnarsdottir advises: “Be aware of the products you use on your skin.” “If you use it every day, the accumulation can be quite large.”
