This PFA is for you: Surprising amount of ‘forever chemicals' found in some American beers, study finds
Beer drinkers should pay attention the next time they imbibe, as they may be consuming more than just alcohol, according to a new study from the American Chemical Society.
It reports that some U.S. beers contain higher than the Environmental Protection Agency's maximum safe levels of polyfluoroalkyl substances, which have come to be known as "forever chemicals" due to the fact that they don't naturally break down or pass through the body.
Other recent reports have found PFAS are present in drinking water across the globe, and the study's author decided to see if those same chemicals were making their way into beer.
"As an occasional beer drinker myself, I wondered whether PFAS in water supplies were making their way into our pints. I hope these findings inspire water treatment strategies and policies that help reduce the likelihood of PFAS in future pours," wrote lead researcher Jennifer Hoponick Redmon.
Breweries do use water filtration and treatment systems to ensure only quality water is being used in their brews, but those systems don't typically block PFAS from entering into the system.
Redmon and her team modified an EPA testing tool analyzing PFAS in drinking water and used it to test 23 U.S. beers.
They selected beers from areas where water-system contamination has already been documented, as well as beers from areas with unknown water systems.
According to the study's findings, some breweries in North Carolina, California, and Michigan had elevated levels of PFAS in their beers.
In 95 percent of the beer tested, PFAS with perfluorooctanesulfonate and perfluorooctanoic acid — both forever chemicals — were present.
Beers from outside the U.S. were also tested. One beer from Holland and two from Mexico were tested, and were found to be less likely to contain PFAS.
"Our findings indicate a strong link between PFAS in drinking water and beer, with beers brewed in areas with higher PFAS in local drinking water translating to higher levels of PFAS in beer, showing that drinking water is a primary route of PFAS contamination in beer," the research team determined.
Last fall, researchers from the University of Birmingham, Southern University of Science and Technology, Shenzhen, and Hainan University, Haikou, published a study that found that forever chemicals were present in water across the world.
PFAS can accumulate in the bodies of living organisms and have been linked to severe health conditions. They are used in different products like pesticides, non-stick cookware, food packaging and cosmetics, and can enter wastewater through many day-to-day activities. Government regulation has banned some, while the use of others is still widespread, with their toxic effects yet to be fully investigated.
They also revealed a wide range of PFAS contamination for target PFAS, beginning at 63 percent of bottled waters tested.

Winds push smoke from Canadian wildfires south into US and worsen air quality
Air quality in some parts of the United States is worsening as smoke from dozens of wildfires in Canada travels south, pushed by winds high in the atmosphere. Air quality in Arrowhead, Minnesota, is deemed unhealthy for people and animals sensitive to pollution and other airborne particles, according to the Environmental Protection Agency's AirNow page. Moderate air quality is being reported across other parts of northeastern Minnesota, northern Wisconsin, the Chicago area, southwestern Michigan and the state's eastern Upper Peninsula, northern Indiana and western Ohio. Over the next day or so, particulates from the burning trees, leaves and other vegetation could reach further south into Oklahoma, Tennessee and Arkansas, said Patrick Ayd, a meteorologist with the National Weather Service in Duluth, Minnesota. Murray Kinsey, owner of a houseboat company just outside of Babbitt, Minnesota, said the sky Friday was 'hazy," but anglers still were fishing on nearby Birch Lake. 'It's getting a little hard to breathe,' Kinsey said. 'But it's not terrible. We've had it before, but it's been way worse.' What is AQI and who is at risk? The Air Quality Index — AQI — measures how clean or polluted the air we breathe is on a daily basis. The index focuses on the health effects that might be experienced within a few hours or days after breathing polluted air. AQI is calculated based on ground-level ozone, particle pollution or particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in this country. The index ranges from green, where the air quality is satisfactory and air pollution poses little or no risk, to maroon, which is considered hazardous. That level comes with health warnings of emergency conditions where everyone is more likely to be affected, according to AirNow. On Friday morning, the AQI showed orange around the Arrowhead, Minnesota, area, which Ayd said is a concern for people with chronic conditions, the elderly and young children. 'They really should limit their time outdoors,' he added. The level below orange is yellow and considered moderate, where the air quality is acceptable. That is what is showing Friday for some other parts of the Midwest. But fine particle levels are expected to reach the red air quality index in northern Minnesota, a level that is unsafe for everyone, according to the Minnesota Pollution Control Agency. The North Dakota Department of Environmental Quality said it is monitoring air quality levels and advised individuals to limit prolonged outdoor activities. To limit exposure to unhealthy air quality, people should stay indoors with windows and doors closed. Avoid heavy exertion outdoors, using fans or swamp coolers that take air from outside, all wood-burning appliances, and lighting candles and incense. Where are the Canadian wildfires? Nearly two dozens wildfires were burning in the Canadian province of Manitoba, which is just north of Minnesota and North Dakota. So far this year, the province had had more than 100 wildfires. On Wednesday, Manitoba declared a state of emergency as the fires forced 17,000 people to evacuate homes in several communities. Canada's wildfire season runs May through September. Its worst-ever wildfire season was in 2023. It choked much of North America with dangerous smoke for months. 'We are getting the smoke,' said Kevin Doom, meteorologist with the National Weather Service in Chicago. 'The winds way up in the atmosphere — 10,000, 20,000 feet up — are blowing in from the north today. Minnesota is kind of taking the brunt at the moment.' 'The wind is going to drag that smoke down over the next day or two,' Doom added. Doom said a little haze was showing Friday morning over Chicago. 'It will keep moving with the wind,' he continued. 'But over time, it will continue to disperse, mix in with the air until it gets thinner and thinner until it fades away.' How did past wildfires impact air quality?

Two years ago, smoky air from wildfires in Canada also shrouded broad swaths of the U.S. and prompted warnings for people to stay inside. ___________________ Williams reported from Detroit.
