I get the liquid on my hands during my monthly chain lubing, and “that is the kind of product that can lead to a lot of exposure”, Schreder said. Research alerted me to their use in some types of parchment paper, which I used to roll tortillas, while the aluminum foil in which I wrapped leftovers raised a red flag with its “nonstick” label. The stations rarely, if ever, used foam, a known source of PFAS, to fight fires. More info. The results and uncertainty are, in a word, distressing. In the kitchen, we confirmed that the parchment paper and nonstick pan used on taco night contained PFAS. “We’re victims, too,” Victor told me. Tom Perkins tested dozens of household items, as well as blood samples from his cat, Ling Ling, for PFAS. Most items were checked twice – once by Galbraith Laboratory, a Knoxville lab that’s considered a leader in toxic chemical testing, and by Notre Dame’s Peaslee, a professor of experimental nuclear physics, chemistry and biochemistry. This site complies with the HONcode standard for trustworthy health information: verify here. Some experts who reviewed the results said they believe a case that I am being slowly poisoned could be made, but they also cautioned that PFAS’s presence in my blood doesn’t necessarily mean I’ll ever become sick. This story was produced by Type Investigations in partnership with Great Lakes Now/Detroit Public TV, Consumer Reports and The Guardian. After spending several months reporting on the PFAS crisis, I had an alarming realization: taco night might be poisoning me. It’s simply not clear how much the PFAS in each item is contributing to the levels in our blood. In fact, a study by scientists from EWG, published in October 2020, used state testing data to estimate that more than 200 million Americans could have PFAS … Saudi Arabia's de facto ruler approved an operation to capture or kill murdered journalist Jamal Khashoggi in 2018, according to U.S. intelligence released on Friday as the United States imposed sanctions on some of those involved but spared the crown prince himself in an effort to preserve relations with the kingdom. The California-based Vista Analytical Laboratory checked my and Ling Ling’s blood for 24 compounds. Advocates say the only solutions are to regulate PFAS as a class of chemicals instead of on an individual basis, and to enact a ban except for essential uses, as the European Union is proposing. Many PFAS are stable and long-lasting in the environment, acquiring the name "forever chemicals." Meanwhile, my couch and carpet may have been treated with Scotchgard or other stain guards that use PFAS to make products stain resistant. News-Medical speaks to Dr. Keiko Ishii about her research efforts during the COVID-19 pandemic and how speaking whilst infected can cause the virus to spread, and why wearing masks is so important. PFAS substances have unique characteristics-resistance to heat, water, oil and stains-that make them useful in a variety of industrial applications and popular in consumer goods. In the US, industry is replacing the older, longer compounds with a newer generation of PFAS that it claims are safer, though that claim is contradicted by a growing body of research. Society of Environmental Toxicology and Chemistry, Posted in: Life Sciences News | Biochemistry, Tags: Bases, Fish, heat, Research, Toxicology. Perkins swabs his shoes so samples can be tested for PFAS. Industrial use of some of these compounds has been halted; however, many derivatives are still in commerce and more are under development. Research shows that PFAS in food packaging can leach into food, and that increases with temperature, duration of contact and other factors, said Laurel Schaider, a PFAS researcher with the Silent Spring Institute. The opinions expressed here are the views of the writer and do not necessarily reflect the views and opinions of News Medical. PFAS were detected in breeding kittiwakes in Svalbard, Norway, and ducks in Australian estuaries. State regulators since 2018 have been monitoring drinking water supplies and my tap water test came back clean, but it’s possible that it has been contaminated in the past. Blood was liquid-liquid extracted and PFASs were determined by liquid chromatography coupled to tandem mass spectrometry. The lumbar pain spreads along the lower leg below the knee, in the calves and/or in the foot. People are dying – what will it take for the Premier to act? Khashoggi, a U.S. resident who wrote opinion … The PFAS and Scotchgard producer 3M acknowledges on its website “possible associations with certain biomarkers or health outcomes in people for PFOA and PFOS”, referring to two older PFAS. Labs detected or I was able to confirm the chemicals’ presence in 15 common products, and there are undoubtedly more in items that weren’t checked. Unless I plan to stop eating out and consuming animal products altogether, for example, then I’m generally going to be exposed to PFAS in food and its packaging. The chemicals’ use in food packaging is widespread. We use cookies to enhance your experience. PFAS applied to products like a carpet, couch or waterproof clothing continually break off and are breathed in, or attach to dust that gets on our hands and is ingested. Tom Perkins’ cat, Ling Ling, whose blood contained PFAS chemicals. Major vaccine developers are testing the efficacy of their vaccines against these and other variants. “It’s not just about keeping somebody from keeling over, it’s about reducing the overall burden of environmentally associated diseases in the US population, which is pretty big.”. The more I dug into the chemicals’ myriad uses, the more I found that I’m potentially exposed to them in nearly every facet of daily life in my house. A normal blood pressure reading is less than 120/80. They were found in hens' eggs, soil, tadpoles, zebrafish, house crickets; the list goes on. Toxic Free Future’s Schreder said she visualizes the protective stain-resistant layer that PFAS form as a shag carpet. According to the Kaiser Family Foundation, the average annual cost of insulin for a Medicare beneficiary went from $862 in 2007 to nearly $4,000 in 2016, calculating for a 358% cost increase.While many factors play a part in rising healthcare costs, the rate of increase in insulin prices is anything but reasonable, giving that since 2007, the value of $1 has seen a rise of less … Fetal alcohol spectrum disorders (FASDs) are a group of conditions that can occur in a person whose mother drank alcohol during pregnancy. In another study published in this same issue, long-chain PFAS were found in eight fish species across ten European glacial lakes in the Alps region, and while correlated to urban areas, could not be attributed to a specific, nearby industry source. For dessert, I purchased cookies that a local bakery packed in the type of paper bags sometimes treated with PFAS, and the chemicals may have been in my tap water and fish. I couldn’t rave on about how much period underwear has changed my life without mentioning the elephant in the room: in 2020, PFAs were found in certain pairs of Thinx menstrual underwear. Ng said commercial labs didn’t have the ability or analytical standards to check our blood for more than about 40 PFAS compounds, but thousands exist. All products are registered Medical Devices in accordance with Directive 93/42/EEC; and are compliant with BS4376:Part 1:1991. We also found the chemicals in carryout packaging from several Detroit restaurants. Procter and Gamble also said in the statement that it tested its floss using a modified version of the EPA 537 method. The PFAS in these products can take several routes into my body, and may partly explain the elevated blood levels. Otherwise, there are very few meaningful steps that we can take, though a water filtration system is one good option. The Fire Research Division develops, verifies, and utilizes measurements and predictive methods to quantify the behavior of fire and means to reduce the impact of fire on people, property, and the environment. In Ling Ling and me, the test found PFOS and PFHxS, which are constituents of firefighting foam, and the former was in Scotchgard until 2003. Our test showed that fluorine composes 17% of Oral-B Glide floss. By contrast, our tests looked for the total level of fluorine, which is the common element in all PFAS, and gives labs a clearer idea of how much PFAS might be in a product. A pinched nerve in the lumbar area can be especially painful and debilitating. Most companies that I contacted for comment didn’t respond. PFAS were detected in breeding kittiwakes in Svalbard, Norway, and ducks in Australian estuaries. “Major improvements can simply be made by medical – as opposed to procedural – interventions, such as the adoption of healthier lifestyles, anti-cholesterol drugs, taking blood pressure and cutting out smoking.” Now we’ve added the premier model to our QSight family: the high performance 400 series. The levels for several compounds are what Graham Peaslee, a University of Notre Dame PFAS researcher, called “unusually high” and at quantities at which toxicologists say they start seeing links to health problems. When left unchecked, high blood pressure can lead to damage to your circulatory system, stroke, heart attack and other health problems.The Rx: See your doctor regularly to have your blood pressure checked. Food packaging was among the items Tom Perkins had tested for PFAS. I set out to answer that question by checking dozens of household items, my tap water and blood samples from my cat, Ling Ling, and me for the chemicals. The compound was commonly used to produce PTFE that was applied to a wide range of consumer products, including the pan I used to fry the fish, bike lube, plumber’s tape and dental floss. Carla Ng, a University of Pittsburgh researcher who models PFAS’s bioaccumulation in organisms, called the persistent cultural misconception that exposure to chemicals isn’t a problem if it doesn’t immediately harm us “old-fashioned”. (Abel, 2/5) The Washington Post: Companies Are Charging … Biochemical Tests for Microbial Identification, The Ethics of Animal Models in Preclinical Testing, DermaSensors: The Future of Skin Cancer Detection, UMD receives grant to explore nettle as a functional food for improving health, Scientists optimize wastewater disinfection process to minimize spread of antibiotic resistance, Aptamer Group Extends Collaboration With Leading Biopharmaceutical Company to Explore Next-Generation Drug Delivery Approaches, Researchers decipher how interspecies interactions arise, evolve and are maintained, CN Bio awarded Innovate UK grant to develop single and multi-organ models for COVID-19 research. Though the amount of PFAS in our blood is minuscule, the levels for each compound (except one) are above US medians, and that could present a health threat, said Erika Schreder, a toxicologist with Toxic Free Future. Home / Blog. In order to manage PFAs in the environment, a lot of research has been directed at understanding their sources, fate and transport in the environment, and their potential effects on humans and wildlife. on this website is designed to support, not to replace the relationship Concerned, Graham Peaslee told me he has switched to waxed floss. Testing confirmed that my and Ling Ling’s blood is contaminated with PFAS. PTFE has also generally been considered a PFAS compound, and the EPA classifies it as such. They’re used in a range of personal care products from moisturizer to bar soap to cosmetics by a number of brands. Tasmania’s health system is in a perpetual crisis Ambulance crews doing fantastic job in extreme conditions People are dying waiting for ambulances while Peter Gutwein and Sarah Courtney fail to … The right stretch, however, can release the nerve from its bind. The chemicals it identified included PFHxS and PFOA, which were found in my blood. PFAS can slip through many filters, but researchers at Duke and North Carolina State universities found reverse osmosis and two-stage filters are the most effective. between patient and physician/doctor and the medical advice they may provide. The synthetic compounds are often used to make thousands of everyday products water, stain and grease resistant, and they’re popular with manufacturers across dozens of industries because they’re so effective. This unknown adds extra layers of anxiety and leaves me wondering if I should run to my doctor for a cancer screening or liver check. This test, however, doesn’t check for PTFE, or most of the 4,700 PFAS compounds. A tool developed by Carignan and Silent Spring shows how my and Ling Ling’s levels compare with those of adult humans living in the US. The pain is strong, continuous, with a burning sensation and numbness of the legs. Industry regularly questions whether any of this is cause for concern.

Blood tests revealed four types of PFAS compounds in my and Ling Ling’s blood. The Seattle-based non-profit studies PFAS contamination and pushes industry to find alternatives to the chemicals. I also got rid of my nonstick Teflon pots and pans, switched dental floss brands, bought a different bike lube (though I’m uncertain if it’s PFAS-free) and have stopped buying any products that I know contain PFAS. PFAS in the House was produced by Great Lakes Now/Detroit Public TV, in partnership with. Testing didn’t find those chemicals in my blood, but that doesn’t mean they aren’t in Ling Ling and me. “There’s the problem of a person’s exposure in their home, and then there’s the problem that [the chemicals were] ever made, and are getting into the environment … then can get into your fish later,” she said. Chemical companies have recently begun making that claim, and argue that it’s safer because it does not necessarily accumulate in the body in the same way as other such compounds. And while testing indicated the chemicals’ use in products throughout my home, it’s unclear how they contributed to my blood’s contamination, and the project often raised more questions than it answered. I sent the results to toxicologists and PFAS researchers who provided insight on what they mean and helped answer my question. Here’s what I learned from investigating my home, Last modified on Tue 23 Feb 2021 18.05 EST. My blood also contains PFNA, which is used in the production of nonstick and stain-resistant coatings. “It’s the fact that PFAS are so pervasive,” Ng said. Hypertension is what happens when the force of blood is consistently too high. Ideal for analyzing food, cannabis, and environmental samples, our robust and reliable QSight^® triple quad systems consistently deliver the throughput and productivity you need in your analytical testing lab. Owned and operated by AZoNetwork, © 2000-2021. In both of us it detected elevated levels of PFOA. Per- and polyfluoroalkyl substances (PFAS) are a class of man-made chemical compounds and a current, emerging concern to environmental health. When I spoke with Avalon International Breads about their cookie bags, Jackie Victor, a co-owner, said she was “shocked” to learn that they contained the chemicals, planned to immediately pull them, and would find an alternative that is PFAS-free. Just as it’s impossible to know how many cigarettes cause cancer, there’s no clear level of exposure to PFAS that will cause health problems. “They can go up into the air, so then they’re contaminating your indoor air in your home and you breathe them in,” she said. The pieces of shag repel water and stains, but, over time, the shag breaks off. Instead of sweeping with a broom, which kicks up dust and contaminants, I now use a vacuum that has a Hepa filter that traps them. It’s possible the chemicals are behind my high cholesterol, though the cookies and milkshakes that are part of my weekly diet could be driving it. The published research illustrates that PFAS are ubiquitous and raise more questions than answers about their potential toxicity to humans and wildlife. Procter and Gamble, which uses PTFE in its Oral B Glide dental floss, stated that Oral B tested negative for the presence of PFAS, and claimed PTFE isn’t PFAS. Symptoms can include an abnormal appearance, short height, low body weight, small head size, poor coordination, behavior problems, learning difficulties and problems with hearing or sight. The chemicals can then accumulate in our organs and could trigger disease. In this interview, News-Medical spoke to Professor Peter Stockley about his latest research that looked at what makes viruses infectious. I soon began to scan my home for products that potentially contained them and anxiously wondered: “Am I being poisoned by a steady drip of PFAS?”. Recently, Environmental Toxicology and Chemistry (ET&C) published a special issue dedicated to PFAS with 32 articles, providing a valuable summarization of risk assessment approaches for PFAS, which are needed for environmental managers and regulatory bodies to set appropriate drinking water standards and health advisory guidelines. By continuing to browse this site you agree to our use of cookies. They were found in hens' eggs, soil, tadpoles, zebrafish, house crickets; the list … Some restaurants probably use at least some packaging that contains them, and some restaurateurs probably aren’t aware. The non-profit studies the chemicals’ use in the food industry and in 2017 found PFAS in nearly 50% of fast food wrappers that it tested. For example, the authors of the article that investigated PFAS in Australian ducks did find a correlation between local sources of PFAS and bioaccumulation in ducks and noted that "Human health risk assessment showed that only ducks inhabiting wetlands near local sources of PFAS were likely to pose a risk to consumers," and continued, "Management of food consumption from these locations is an effective measure to limit exposure.". How can we protect ourselves? The PFAS have been replaced by stain guards free of the chemicals. Trying to identify the chemicals’ sources is a bit maddening and stressful. Exposure to pieces of furniture that I owned before my current couch, which I bought two years ago, could be behind some of the PFAS levels in my and Ling Ling’s blood, Schreder said. Public health advocates and researchers say there’s only one real way to protect ourselves – a virtual ban on PFAS production. The testing was performed by two independent laboratories that are among the few nationwide that can conduct such analyses. That also makes it difficult to draw a clear link between the compounds found in my blood and anything currently in my home, said Courtney Carignan, an environmental epidemiologist with Michigan State University. This work involves integration of laboratory … “What we ate yesterday can stay in our bodies for years,” Schaider said. That’s a problem because the class of about 4,700 compounds is linked to serious health problems like cancer, heart disease, birth defects, liver disease and decreased immunity. Research has found that PFAS might also be in my dental floss, waterproof boots, umbrella, mattress pad, bike chain lube, cellphone, clothing, camping gear and more. The extent of PFAS contamination is only now coming into focus – studies have found drinking water supplies for well over 100 million people across demographic lines may be contaminated by the chemicals. News-Medical speaks to Dr. Mahshid Dehghan about her latest research into diet, and how a diet high in carbohydrates could increase your risk of heart disease. Please note that medical information found Molded fiber products, for example, categorically contained the chemicals until last year. But PFAS, dubbed “forever chemicals” because they don’t naturally break down, aren’t only lurking in the kitchen. “It’s not just in electronics, healthcare products or consumer products – it’s in all of those things, which makes [the project] nearly impossible because they’re coming from so many places.”. “We’re understanding that a lot of the long-term chronic disease that people have can links back to these cumulative exposures over their lifetime,” Ng added. I learned that the type of nonstick pans that I used to fry the fish usually contain the toxic chemicals, also called per- and polyfluoroalkyl substances. It’s simply not clear how much the PFAS in each item is contributing to the levels in our blood. “Then you convert them in your body into these highly persistent compounds.”. While the lab results provide useful information, the chemicals’ nature, and sheer ubiquity, gaps in testing capabilities and industry data make it nearly impossible to get an accurate read of how much PFAS are in our bodies. Tom Perkins is a Detroit-based freelance journalist, The poison found in everyone, even unborn babies – and who is responsible for it | Rob Bilott. The series provided a great review of the state of the science of PFAs risk assessment and also identified data gaps and the work needed to fill them in order to devise an effective approach to manage PFAS. Labcold Blood Bank Refrigerators, Plasma Freezers, Platelet Agitators and Incubators are all manufactured in the UK in full compliance with ISO quality management specifications. The tests confirmed the presence of fluorine, which indicates PFAS, in my bike chain lube, several types of food packaging, a small mat treated with Scotchgard, waterproof boots, cookware and Oral B Glide dental floss. “Unfortunately, we do see that typical levels can be tied to certain health issues, like reduced immunity, so that is definitely a concern,” Schreder said after reviewing my results. The extent of PFAS contamination is only now coming into focus. Our mission is to harness independent science and agroecological concepts to advocate for … The articles in the issue report that PFAS were found near defense bases, urban environments, treatment plants and waste disposal sites but also in remote, less inhabited areas. The regulatory approach as it’s currently designed is ineffective. While some of the chemicals are probably present in products in my home, Galbraith’s test tells us how much fluorine is in the items, but doesn’t identify individual PFAS compounds. Tom Perkins. “It’s fundamentally unfair that we have to deal with this for the convenience of not having eggs stick to the pan.”. The breadth of the published research illustrates that PFAS have dispersed in every medium in the environment (soil, water and wildlife). They’re among the most common used by industry, and three exceeded the median US blood levels for adult humans. PFAS are now found in many compartments of the environment. Ling Ling and I may still be exposed to the chemicals and I worry about what it could mean for us 10 or 20 years down the road. Researchers told me furniture, carpets and shoes treated with stain protectors like Scotchgard are a prevalent source of PFOS contamination in my house and Americans’ blood, and that PFAS compound was found in my blood. Silent Spring later analyzed federal PFAS data and found a significant correlation between people who eat out and higher levels of the chemicals in their blood. By some estimates, up to 90% of carpets on the market were treated with PFAS products until the industry shifted away from them last year. In my house, my waterproof Sorel boots and the small mat in my basement that had been treated with Scotchgard put me at potential risk for this type of exposure. Experts with whom I spoke say almost certainly, but this is where the picture gets especially fuzzy. It’s estimated that they’re present in 97% of Americans’ blood, and public health advocates are just starting to understand how widespread their use is in everyday products. Blood PFAS results can be received for free and a gift card of up to $55 will be offered. Experts with whom I spoke said it was also possible that the chemicals are in our food, especially fish, which Ling Ling and I regularly eat. The compounds used during the manufacturing process or when products containing PFAS are put in a landfill can eventually migrate to drinking water supplies and the food chain. Anyone living in those areas and wants to enroll in the study can call 855.322.3037. rying to identify the chemicals’ sources is a bit maddening and stressful. Sorel didn’t respond to requests for comment. It’s also difficult to connect the dots between the chemicals in my blood and home with any precision. “You worry because these are in your blood, and they may have been in your blood for a long time, so it’s hard to know if a health condition that develops is caused by PFAS exposure, but that will be in the back of your mind,” Ng she said. Indeed, Ling Ling had higher levels of two compounds than I did. Testing confirmed that my and Ling Ling’s blood is contaminated with PFAS. PFAS are also turning up in livestock and crops via pesticides, contaminated sewage sludge used as fertilizer, and contaminated water used on farms. What else? What about regulation? with these terms and conditions. Courtney Carignan, an environmental epidemiologist with Michigan State University, said these are good steps to take, but people who are “trying to buy their way out of a problem” may get a “false sense of security”. However, in a statement, a spokesperson said that the “weight of scientific evidence from decades of research does not show that PFOS or PFOA causes harm in people at current or historical levels”. But recent phase 2/3 data from both Novavax and Johnson & Johnson suggest reduced protection against the South African variant. But my research a decade ago showed, in many cases, these procedures are unnecessary or cause net harm,” says Abbott. Several experts who reviewed my tests were alarmed by the bike lube’s levels, which were the highest of any product in the house. Could a diet high in carbohydrates increase your risk of heart disease? But experts who spoke with me say there isn’t enough independent science to determine whether PTFE is safe or not. In some of the studies, the presence of PFAS was related to a nearby source while in others it was not determined. Welcome to Separation Science. That followed proposals to ban PFAS-treated carpets in several states and decisions by retailers like Home Depot and Lowe’s to stop selling Scotchgard-treated carpets. Studies have found pets like Ling Ling often have higher levels of PFAS in their blood than humans, partly because they’re smaller, and partly because “if you’re a toddler or a cat, then you spend a lot more time kind of interacting with house dust,” Schreder said.
