Alarming Levels of Toxic 'Forever Chemicals' Detected in Blood of North Yorkshire Town Residents
Exclusive blood testing conducted in the small rural town of Bentham, North Yorkshire, has uncovered alarming levels of toxic per- and polyfluoroalkyl substances, commonly known as Pfas or forever chemicals, in the blood of residents and former factory workers. This discovery follows a previous investigation that revealed Bentham as the site of the highest recorded Pfas contamination in the United Kingdom.
Pfas are notorious for their persistence in the environment and have been linked to a wide range of serious health conditions, including certain cancers, reproductive problems, and other adverse effects. These chemicals are extensively used in various consumer products, with one of their most prolific applications being in firefighting foam.
Groundbreaking Investigation and Blood Test Results
In May 2024, an investigation by Ends Report and the Guardian exposed that groundwater in Bentham was contaminated with unprecedented levels of Pfas. This contamination was traced to land belonging to Angus Fire, a factory that legally produced Pfas-containing firefighting foam from 1976 to 2024. As part of a new ITV documentary, blood testing has now revealed that individuals in the area have disturbingly high concentrations of these chemicals in their bloodstreams.
In the United Kingdom, there are no established guidelines defining safe levels of Pfas in blood. However, in the United States, the National Academies of Sciences, Engineering, and Medicine has indicated that a sum of seven Pfas chemicals exceeding 2 nanograms per milliliter in blood poses a potential risk for adverse health effects. Shockingly, the highest Pfas level recorded in Bentham was 405 ng/ml, which is more than 200 times greater than this US risk threshold. This extreme level was found in a former Angus Fire worker who has chosen to remain anonymous.
Furthermore, if Pfas levels surpass 20 ng/ml, Nasem recommends that clinicians consider more frequent and targeted health screenings due to an increased risk of adverse effects. Among the 39 people tested in Bentham, almost a quarter, or 23%, fell into this highest risk category. One such individual is 34-year-old Stephen Illston, who has a Pfas level of 55 ng/ml. Illston has faced significant challenges in conceiving children, attributing his infertility issues to poor mental health and years of self-doubt. He expressed relief upon learning about his elevated Pfas levels, stating it provided an answer he had long sought.
Expert Analysis and Community Exposure Concerns
Dr. David Megson, a forensic environmental scientist and Pfas expert at Manchester Metropolitan University, conducted an analysis comparing the Bentham blood results to Pfas levels in the US population. He described the data as absolutely shocking and exceptionally high, with nearly all tested individuals above average and two-thirds in the top 5% of the background population. Dr. Shubhi Sharma from the environmental charity Chem Trust echoed these concerns, highlighting the alarming levels and their association with various adverse health outcomes, including cancers.
An internal Environment Agency report from 2024 suggested that aerial dispersal from foam testing at the Angus Fire factory could be a likely pathway for community exposure. The report noted that this could lead to Pfas contamination through the consumption of allotment produce and home-grown vegetables, with the probability considered likely. Dr. Tony Fletcher, an epidemiologist and world-leading Pfas expert, supported this, explaining that chemicals from test fires could become airborne, settle on the ground, and infiltrate water or food sources.
Resident Lindsay Young, who has a Pfas level of 30 ng/ml, described frequent test fires at the factory, accompanied by billowing black smoke that forced residents indoors without knowledge of its contents. In response, an Angus Fire spokesperson argued that the risk in the Environment Agency report was overstated, emphasizing that the company responsibly conducted routine fire tests and had ceased testing Pfas foams in Bentham by 2022. They also contended that former operations were not the sole source of Pfas in the area and criticized the blood data as unfounded due to the small test group and lack of international consensus on interpretation.
Regulatory Gaps and Potential Mitigation Strategies
The Environment Agency stated that fire testing was not regulated under the site's permit, placing responsibility on the local council. North Yorkshire council, however, cited exemptions under the Clean Air Act 1993 due to the company's firefighting connection, allowing the emissions. Dr. Fletcher, who advises the Jersey government on similar Pfas contamination from airport firefighting foams, recommended that individuals in Bentham with elevated levels discuss options like colesevelam, a cholesterol drug shown to lower Pfas, or bloodletting with physicians.
Angus Fire expressed regret for the inconvenience and worry caused, asserting that they have diligently worked with environmental consultants and the Environment Agency to address contamination and followed UK regulatory guidelines. The documentary, In Our Blood: The Forever Chemicals Scandal, will broadcast on ITV1 and ITVX, shedding further light on this pressing environmental and public health issue.
