Scientists from Indiana University, the University of Washington and the nonprofit Toxic-Free Future said they were concerned after finding high levels of the chemical in everything from cosmetics to furniture. contained in the milk of mothers in the United States. This is up to 2000 times greater than what is claimed to be safe in drinking water.
New research shows that toxic chemicals were found in 100% of breast milk samples from mothers in the US. The researchers tested 50 samples and all tested positive for PFAS, a man-made chemical that doesn’t break down in the environment and is linked to a number of health problems.
PFAS are known as ‘permanent chemicals’, containing compounds that can contaminate soil and water sources and damage fertilizers. They can also stay in the body for days or even months before being eliminated, increasing the risk of serious disorders, birth defects and even cancer.
What’s more, the team says, in some cases, levels were 2,000 times higher than those deemed acceptable by US health and environmental agencies.
The new study looked at breast milk samples from 50 US mothers and found the chemical PFAS in 100% of the samples.
Co-author Erica Schreder, chief scientific officer of Toxic-Free Future, said: “Research shows that PFAS contamination in breast milk is potentially widespread in the US and that these toxic chemicals are harming something that’s not already present. should be nature’s perfect food.”
PFAS, or per- and polyfluoroalkyl, are man-made chemicals that have been used in several industries around the world since the 1940s. According to the Centers for Disease Control and Prevention, they are ubiquitous. , from cosmetics, waterproof clothing to grease removal products. PFAS can also be found in molded fiber bowls, which are served at many takeout locations and are responsible for a large amount of waste.
The team says this is the first study in 15 years to look at PFAS in breast milk samples. All samples were obtained from mothers in the United States, tested for 9 short-chain compounds and 30 long-chain compounds.
Short-chain PFAS compounds, which are thought to be less dangerous than long-chain compounds, can remain in the body for days or even months before being completely eliminated. In total, 16 compounds were detected. Some were found in about 4% of samples and others up to 100%.
PFAS levels were found in concentrations ranging from 50 parts per trillion (ppt) to 1,850 ppt with an average concentration of 121 ppt. There are currently no guidelines or appropriate thresholds for PFAS levels in breast milk. However, the Environmental Working Group, an advocacy organization, recommends no more than 1ppt in drinks. Additionally, the CDC’s Registry of Toxic Substances and Diseases, recommends a limit of 52 ppt for adults and 14 ppt for children.
Co-author Dr. Sheela Sathyanarayana, a pediatrician at the University of Washington, says that there are few studies looking at the effects of PFAS on infants. However, previous studies have found that these chemicals may affect older children by disrupting the hormone system.
