#KnowledgeBit: #Polyfluoroalkyl substances or "forever chemicals," PFAS for short are chemicals that are widespread in the environment due to human production and release of these chemicals.

These are so durable that they are referred to as "#ForeverChemicals"; and have detrimental health concerns not yet fully understood.

Tribes addressing the ‘#forever #chemical’ problem

Two years after the Environmental Protection Agency found high levels of #Perfluoroalkyl and #Polyfluoroalkyl Substances

#PFAS #contamination in the drinking water at the K-12 tribal school on the Leech Lake Reservation,
💥students and staff are still forced to consume only water brought in from outside the building.

Leech Lake is one place tribes are having to respond to the presence of PFAS -- a class of man-made chemicals used in fire suppressing foam, water repellents on textiles, and older nonstick cookware.

⚠️High PFAS exposure is connected to some health problems including cancer and thyroid disease.

🔥Nearly 100% of Americans have PFAS in their body. Information specific to #Native #Americans is limited.

Join Native America Calling to talk with some tribes that are trying to address PFAS in their water and explore what can be done.

#FloorWaxing could be an important source of #PFAS #contamination, with increased #occupational health risks for #workers

May 25, 2022

"There’s a special satisfaction that comes from walking on perfectly shined floors — but is it worth the potential risk to floor waxing workers?

"A study published earlier this year measured per- and #polyfluoroalkyl substances (PFAS) in #dust and airborne #ParticulateMatter [which means it's going into the air that everyone breathes -- just not humans] during professional floor stripping and waxing. After estimating PFAS emission rates generated from the process, researchers concluded that significantly higher levels of PFAS were present during floor waxing.

"The study was led by Jiaqi Zhou, PhD, a postdoctoral researcher in the Department of Environmental Sciences and Engineering at the UNC-Chapel Hill Gillings School of Global Public Health. Collaborators include Karsten Baumann; Naomi Chang; Glenn Morrison; Wanda Bodnar; Zhenfa Zhang; Jason Surratt; and Barbara J. Turpin — all with the Gillings School — and Joanna M. Atkin, with UNC’s Department of Chemistry.

"PFAS are human-produced chemicals commonly used in industry and consumer products. Most PFAS do not break down over time, so they remain in the environment and in the bodies of exposed human and #animals long after initial use. Scientific studies have shown that exposure to PFAS may be linked to harmful health effects, which was the impetus for this study.

"Published in Atmospheric Environment, the paper reports that floor waxing floor waxing workers could have increased occupational health risks due to PFAS exposures.

“Assessment of occupational exposure due to floor maintenance is important because PFAS exposures can lead to increased risk of #cancer, #immunotoxicity and #neurodevelopmental problems, the co-authors write."

This article goes on to talk about how to limit #PFAS exposure. Too bad animals can't read news articles. But seriously, I wonder how many animals suffer from cancer as a result of PFAS? I mean, it's in the RAIN! Kinda hard to avoid rainwater -- especially if you live in nature and don't have water filters. smh

Study finds concerning contributing factor to childhood #cancer: ‘These findings have important public health implications’

Story by Laurelle Stelle

"One of the most tragic and mystifying conditions a human being can experience is childhood leukemia. This potentially deadly cancer occurs at an incredibly young age before the patient has even been exposed to most of the risk factors usually associated with cancer.

"However, Environmental Health News (EHN) reports that a recent large study published in the Journal of the National Cancer Institute links childhood leukemia to a frighteningly common type of chemical: PFAS.

"PFAS (#perfluoroalkyl and #polyfluoroalkyl substances), also known as 'forever chemicals,' are a class of chemicals used in as many as 88% of #HouseholdProducts, especially those with #nonstick, #StainResistant, and #WaterResistant treatments. They’re called forever chemicals because they take an astronomically long time to break down, building up in the #environment instead as more are released.

"Unfortunately, PFAS have been found in water sources all over the world, including #raindrops, and they have been suspected as a likely cause of cancer."
