What PFAS in rainwater implies for your health

Perfluoroalkyl substances (PFAS), sometimes known as “forever chemicals,” are a well-recognized threat to worldwide human health.

Because these manmade chemicals pollute the natural environment, including drinking water, research has linked PFAS exposure to a variety of health problems, including liver damage, infertility in women, gestational diabetes, and some malignancies.

According to a new study from Stockholm University, the amount of PFAS in rainfall exceeds the Lifetime Drinking Water Health Advisory thresholds set by the United States Environmental Protection Agency (EPA). Rainwater is frequently found to be over the Environmental Quality Standard for Inland European Union Surface Water, according to the researchers.

How PFAS get into drinking water

PFAS was first created in the 1940sReliable Source. Manufacturers used PFAS in a number of items ranging from nonstick cookware to cosmetics due to their unique features such as their ability to repel water and oil and to be temperature resistant.

When a factory manufactures or utilises PFAS, it can contaminate the natural water, land, and air surrounding it. PFAS-containing products in landfills can also leach toxins into the surrounding environment over time.

When this happens, the chemicals can damage food grown in the soil, streams and lakes that feed drinking water reservoirs, or the habitats of the fish we consume.

Furthermore, PFAS can travel through the air and become part of the world’s environment, as evidenced by study that discovered PFAS in Arctic ice and soil. When this happens, PFAS can enter rainwater and potentially contaminate water supplies all around the world.
