Larger area of water in Jersey contaminated with chemicals
'Evolving science'
The high levels are linked to the historic use of firefighting foam at the airport.Deputy Steve Luce, the minister for the environment, is to review the findings and produce a full response by 12 June, "including details of how the Government will move remediation options forward".Luce welcomed the report and said: "PFAS is not just in Jersey, it's everywhere. But we're coming up with scientific, evidence-based solutions to deal with it. There are only a few other jurisdictions around the world who are doing as much as we are."We are following the evolving science. We commissioned this report to give us a better understanding of where PFAS is and what we can do about it. "It is a detailed report on a complex matter and its findings deserve proper consideration."

'Forever toxins' found in everything from cosmetics to waterproof clothing linked to weight struggle
Toxins found in everything from cosmetics to waterproof clothing could hinder weight loss, a study has shown. Researchers have discovered that levels of so-called 'forever' chemicals in the blood may, in the long term, lead to people piling the pounds back on after shedding them. Per- and polyfluoroalkyl substances (PFAS) are in hundreds of everyday products because of their durability. But last year a review of 500 studies found they were linked to 'serious health implications', including weakening the immune system and cancer. The Government is set to receive recommendations from a panel of experts later this year on how levels of PFAS can be reduced. Now researchers say the chemicals may also affect the body's metabolic process – which is how it converts food into nutrients. In the study, published in the Journal Of Obesity this week, researchers assessed 186 teenagers who had bariatric surgery – which works by making the stomach smaller and the patient feel fuller quicker. After the surgery, patients are at risk of slowly putting weight back on, and the researchers found people with high levels of PFAS were at a greater risk. They tested the participants' blood for levels of PFAS before the surgery and found that those with the highest levels of the chemicals put on twice as much weight in the five years after the surgery compared to those with the lowest levels. 'With the growing use of weight loss interventions around the world, it's critical for us to understand the association between PFAS and successful weight loss management, including what this means for long-term outcomes,' said Dr Brittney Baumert, a researcher at the University of Southern California's Keck School of Medicine who led the study. 'PFAS are a modifiable risk, which is why protective policies are so important to reduce exposure and safeguard public health – especially for vulnerable populations.' Experts say that while their research looked specifically at bariatric surgery, the findings may also be relevant for people on fat jabs. 'We're also interested in exploring whether PFAS exposure is relevant to other weight loss interventions, including GLP-1 medications such as Ozempic,' said Dr Baumert.

Exposure to some common Pfas changes gene activity, new study finds
New research suggests exposure to some common Pfas or 'forever chemical' compounds causes changes to gene activity, and those changes are linked to health problems including multiple cancers, neurological disorders and autoimmune disease. The findings are a major step toward determining the mechanism by which the chemicals cause disease and could help doctors identify, detect and treat health problems for those exposed to Pfas before the issues advance. The research may also point toward other diseases potentially caused by Pfas that have not yet been identified, the authors said. The study is among the first to examine how Pfas chemicals impact gene activity, called epigenetics. 'This gives us a hint as to which genes and which Pfas might be important,' said Melissa Furlong, a University of Arizona College of Public Health Pfas researcher and study lead author. Pfas are a class of about 15,000 compounds most frequently used to make products water-, stain- and grease-resistant. They have been linked to cancer, birth defects, decreased immunity, high cholesterol, kidney disease and a range of other serious health problems. They are dubbed 'forever chemicals' because they do not naturally break down in the environment The study checked the blood of about 300 firefighters from four departments across the country who were exposed to high levels of Pfas. The chemicals are the main ingredient in most firefighting foam, and are frequently used in 'turnout gear' worn by firefighters because of their heat repelling properties Furlong said she was surprised to find the number of genes and biological pathways that were impacted by Pfas, which suggests the chemicals may cause or contribute to a broad range of health problems. The study did not prove the chemicals cause certain diseases, but findings point to biological changes that might precede disease. Genes play a range of roles in developing or preventing disease, and Pfas essentially change the way the genes are supposed to act, Furlong said. A gene may act as tumor suppressor, but the Pfas interferes with how it expresses, which affects whether cancer develops, or the type of cancer. For example, PFOS, among the most common and dangerous Pfas compounds, reduces levels of miR-128-1-5p, a gene tied to cancer development. Branched forms of PFOS were linked to changes in five other genes, including some that regulate cancer development.

Not all compounds impacted gene expressions. The research found connections among Pfas-related gene changes and biological pathways involved in leukemia, as well as bladder, liver, thyroid and breast cancers. Other genes and biological pathways were involved in Alzheimer's disease, and autoimmune and infectious diseases such as lupus, asthma and tuberculosis. Furlong said it remains unclear at which step in the biological processes disease is triggered, but the picture is clear enough to point to possible treatments. Pharmaceutical companies are trying to develop drugs that could alter gene activity and potentially prevent Pfas-linked disease from developing.
